Transcontinental Railroad Pictures and Exhibits  

NSDL National Science Digital Library

While it's impossible to take a transcontinental ride across the United States on the Union Pacific (the railroad doesn't exist anymore), visitors can get a sense of what such a ride would have been like via this fine set of digital exhibits. The Central Pacific Railroad Museum has been online since 1999, and it has grown from a few modest galleries of photographs to include thousands of stereoviews, photographs, engravings, maps, and ephemera. The different sections of the site include "steam locomotives", "Sierra Grade Construction Views", and "railroad maps". The materials on the site are a bit difficult to search, so it can be a challenge to find material quickly. Visitors shouldn't miss Nelson's 1871 Central Pacific Railroad (CPRR) guidebook, which contains a set of lovely renderings of the way west along the rails. The site is rounded out by a FAQ section.

History of transcontinental railroads and coal mining on the Northern Plains to 1920  

SciTech Connect

This history examines the symbiotic relationship between three transcontinental railroads-the Union Pacific, Northern Pacific, and Great Northern-and coal mining in Montana, North Dakota, and Wyoming through 1920. Throughout their dual existence, American railroads and the coal industry enjoyed a mutually beneficial association. On the Northern Plains, however, this partnership assumed new dimensions. There, the coal and rails exerted unique influences upon one another. The location of deposits determined many of the transcontinentals' early decisions, especially route selection. The native fuel also was used to promote settlement on railroad lands. Two of the roads, the Union Pacific and Northern Pacific, held land grants containing valuable deposits. The Great Northern, having no such subsidy, acquired coal lands in northern Montana. On these properties, the three railroads pioneered the region's commercial coal mining industry. Eventually, each formed subsidiaries to direct their coal operations. While much of their production supplied steam locomotives, some was sold to the public. Furthermore, the policies of the Northern Pacific and Great Northern especially enabled their coal to stimulate non-railroad enterprises. In addition, all three provided the transportation which made exploitation by others economically feasible.

Transcontinental hydrometeorological extremes and streamflow generation in the Pacific Coast  

NASA Astrophysics Data System (ADS)

Streamflow is a key integrative variable of the hydrologic cycle at the basin scale. In regions along the Pacific coast of the Americas, the role of streamflow varies according to varying physical, biological, and socioeconomical contexts. Improving our understanding of the relationships between those components is a key element to improving the predictability of water availability to sustain food and energy security. However, it is still unclear how large-scale phenomena such as El Niño - Southern Oscillation affect streamflow generation along the Pacific Coast. The present work aims (a) to understand the temporal variability and spatial distribution of hydrometeorological extremes in different basins along the Pacific Coast and (b) how hydrometeorological extreme events contribute to the water year. We hypothesize that hydrometeorologic extreme contributions are to some extent regulated by ENSO, increasing their effect on streamflow generation during extreme-wet and -dry years. Hydrometeorological extreme events are estimated through the use of percentiles of precipitation and streamflow based on a GEV distribution. We assess the Sacramento River Basin (USA), Yaqui and Grijalva River Basins (Mexico) and Chillon River Basin (Perú). Preliminary results show important effects of ENSO negative phase (La Niña) on large streamflow generation in the Grijalva River Basin (Mexico), while in the Sacramento River Basin (USA), the effect is more conspicuous during El Niño, affecting the sustainability of hydropower generation and agricultural activities.

A.J. Russell Photographs of the Construction of the Union Pacific Railroad  

NSDL National Science Digital Library

Born in 1828 in Nunda, New York, Andrew J. Russell worked as a portrait and landscape painter as a young man. In 1862, he organized a local militia unit for service in the Civil War and he learned the craft of photography along the way. Several years later in 1868, he began a project to document the construction of the Union Pacific railroad during its long march to its meeting point with the Central Pacific in Promontory Point, Utah. Russell made three trips west in 1868 and 1869, and he made several hundred plate negatives as part of his extensive work. The Yale Collection of Western Americana has a great deal of his work, and this digital collection brings together a diverse set of these materials for consideration by the public. On the site, visitors can browse through these images, which include bridge construction photographs, shots of the surrounding landscapes, and men at work.

Union Pacific: History and Photos  

NSDL National Science Digital Library

Created in 1862 to construct half of the first transcontinental railroad, Union Pacific (UP) became one of America's leading railroads, hauling passengers and freight through some of the most rugged and scenic regions of America. Anyone with an interest in American railroads, from hardcore trainspotters to the mildly curious will enjoy this site, which celebrates UP's long history with short texts and a plethora of photos and images. Users can read about the caboose and passenger trains, learn about historic UP yards and shops, and review several chronologies. The heart of the site, however, is the photo gallery, which features images of historic advertisements, structures and yards, nineteenth-century stereo views, scenic locations, and a large number of trains (steam and diesel) in action. Take a ride on the rails.

Transcontinental Tidal Gravity Profile across the United States.  

PubMed

Data obtained from a transcontinental tidal gravity profile across the United States were analyzed. Results for the principal tidal constituents M(2) and O(1) have shed light on the long-standing problem of the indirect influence of ocean tides on the solid-earth tide. The profile consists of nine observational stations distributed almost evenly around latitudes 39 to 41 degrees north across the United States. The observed values of the gravimetric factor and the phase were found to depend on the tidal characteristics of the Atlantic and Pacific oceans. There is no observable correlation between tidal gravity parameters and the regional geology. When the influence of ocean tides is taken into account, it is possible for the first time to bring the gravimetric factors and phases for all the stations of a transcontinental network into a consistent system within the framework of the earth tidal theory.

First demonstration of transcontinental SQUID magnetometry (Invited)  

NASA Astrophysics Data System (ADS)

We present the first simultaneous measurements from an ultra-sensitive dual-node transcontinental SQUID magnetometer network, available in real time on the internet. A three-axis low temperature SQUID sensor at LSBB Underground Research Laboratory, Rustrel, France (43.841 N, 5.484 E) and a two-axis high temperature SQUID sensor at SANSA Space Science in Hermanus, South Africa (34.424 S, 19.223 E), form the sensitive nodes of the network. Data are measured and GPS time stamped continuously at 125 Hz. The low-Tc SQUID at LSBB URL (known as a [SQUID]2 system) is inside a shielded steel capsule underneath 500 meters of karstic rock, which allows a low magnetic noise floor. The less sensitive high-Tc SQUID at SANSA Space Science is completely unshielded, and housed only in a magnetically neutral hut, 50 metres from a calibrated fluxgate node of the INTERMAGNET network, to protect it against the weather. The network, which is more sensitive than observatory fluxgate magnetometers, detects Earth's magnetosphere pulsations, Schumann waves, mesopause resonance, breathing modes of the Earth and oceanic swell. Our goal is further to extract directional or polarization information if earthquake precursors are observed again, as with the Sichuan-Wenchuan earthquake on 12 May 2008. In the medium term, we are exploring the possibility to extend the network with more spatially distributed SQUID sensors, such as at the South African National Antarctic Expedition's SANAE IV base in Antarctica.

Railroading Powder River style: bigger investments and bigger trains  

SciTech Connect

The Joint Line, co-owned and operated by Union Pacific and Burlington Norfolk Santa Fe (BNSF) railroads, carried a record 354 million tons of coal from Wyoming's Powder River Basin, on 15,000 to 17,000 ton trains. The average haul is almost 1,000 miles. Torrential rainfall and coal dust caused derailment and buckling problems in 2005. The article reports progress in repairing the track and expanding railroad capacity since then. Many are anxious about the railroad's ability to move ever increasing amounts of coal. 3 photos.

The Butte, Anaconda & Pacific Railway (BA&P) was a standard gauge common carrier short line railroad within the state of Montana. A subsidiary of the Anaconda Copper Mining Company, the BA&P was built to carry ore from mines at Butte, Montana to Anaconda, twenty-six miles away, for concentrating and smelting. Other freight and passenger business was of secondary importance. In 1912, when General Electric contracted to convert the BA&P from steam to electric operation, the short line became a proving ground for main line railroad electrification, and the center of attention from advocates for electric power. Electric operation was demonstrated to be mechanically superior to the use of steam locomotives on the BA&P. Immediately after the BA&P proved the technological feasibility of high voltage direct current for moving heavy freight trains, the Chicago Milwaukee & St. Paul (CM&St.P) electrified over 600 miles of transcontinental main line using the basic technology demonstrated on the BA&P. However, on long distances of track with relatively few trains such as the CM&St.P, the capital cost of the electric distribution system exceeded the operational savings obtained by use of electric locomotives. Steam locomotives remained the primary form of railroad motive power in the United States until the 1950's, when the diesel-electric locomotive combined the mechanical efficiency of electric motors with an on-board diesel generating plant, eliminating the need for expensive electric power supply and distribution wires of conventional electrics. The BA&P purchased three diesels in the early 1950's, but relied primarily on its electric locomotives until 1967, when diesel operation became less costly than continued use of electric motive power. The BA&P offers a microcosmic view of the transformation of one industry in response to technological and economic forces as the United States moved from reliance on coal-burning steam power to electric power and internal combustion. The differing equipment needs of mining companies and railroad companies are also examined in the history of the BA&P.

Transcontinental Arch — a pattern formed by rejuvenation of local features across central North America  

NASA Astrophysics Data System (ADS)

The Transcontinental Arch has been described by many authors as a feature having significant tectonic influence during the Phanerozoic, although the location, magnitude, and even the timing defining the arch vary greatly among authors. The general trend usually suggested for the Transcontinental Arch is northeast-southwest across the western midcontinent of North America. A series of isopachous and paleogeologic maps was compiled for this study that defines a number of smaller tectonic features — commonly trending northwest-southeast. Six persistent highs and six persistent lows (or sags) are defined that are largely basement controlled and were rejuvenated at various times during the Phanerozoic. These smaller northwest-trending features, when taken collectively and enhanced by the relative downwarping of the adjacent Williston and Anadarko basins, create a platform-like feature — the Transcontinental Arch of the literature. The concept of a Transcontinental Arch is an important reference trend in the geologic history of North America. In both regional and local studies, however, the smaller-scale, transverse features may have had significant control on both tectonic patterns and depositional influence.

Railroads: The Transformation of Capitalism  

NSDL National Science Digital Library

During the 19th and early 20th century, the railroad was the reigning king of American industry. A range of short and long haul railroads built and used over 240,000 miles of track from north to south and east to west. This fascinating online exhibit from Harvard Business School's Baker Library looks at how these companies transformed American business, and makes some comparisons with European railroad companies. The materials here are divided into ten sections, including British Railroads, Mass Distribution, Finance, and Management. Each section includes primary documents such as receipts, maps, and internal memos that illustrate how these various companies interacted with each other and the government. The Finance section is utterly engaging, as it discusses (in brief) how railroads were able to corral large amounts of capital for construction and operations across a vast "playing field" of operations.

Railroad and Locomotive Technology Roadmap  

NSDL National Science Digital Library

The Transportation Technology Research and Development Center at Argonne National Laboratory produced this roadmap in December 2002. The 70-page document mainly focuses on energy saving techniques to increase the fuel efficiency of diesel engines. A research objective identified in the report is to improve "total railroad average fuel efficiency by 50% by 2020," and ways to accomplish this goal are outlined. Alternative fuels, electric locomotives, and other power technologies are also discussed. The roadmap analyzes almost every system and factor involved in railroad design -- including motors, rolling resistance, and aerodynamics -- to determine how to approach the energy savings problem.

The Paleo-Lena River - 200 My of Transcontinental Zircon Transport in Siberia  

NASA Astrophysics Data System (ADS)

An immense wedge of Carboniferous to Jurassic siliciclastic deltaic and marine strata accumulated on the Verkhoyansk passive margin of the Siberian craton. U-Pb ages of detrital zircons from Pennsylvanian to Middle Jurassic sandstones are remarkably consistent and show a systematic change in the proportion of zircon age populations through the stratigraphic section that reflects the evolution of the ancient drainage system. Most zircons originated from the orogenic belts along the southern margin of Siberia and were transported thousands of kilometers to the Verkhoyansk margin by a major transcontinental river system, the paleo-Lena, that existed for about 200 m.y. Specific sources for zircons are the Angara-Vitim batholith of Transbaikalia (315 and 291-288 Ma age peaks), plutons of the Altay-Sayan region of the Central Asia foldbelt (494-482 Ma), Proterozoic granitoids of northern Transbaikalia and the East Sayan Range (1888-1832 Ma), and minor contributions from the Siberian Platform and Aldan Shield (2900-2300 Ma). The long sedimentary transport documented for the paleo-Lena River system was comparable to Permian and Jurassic transcontinental rivers that transported sand from the Appalachians to the Colorado Plateau region (Dickinson and Gehrels, 2003). This contrasts with sands of the modern Amazon where the population of far-traveled zircon decreases with increasing distance from the headwaters and eventually becomes overwhelmed by more proximally derived zircon (Rino et al., 2004; Mapes et al., 2005). The paleo-Lena met its demise when the Verkhoyansk margin was deformed in the Late Jurassic and Cretaceous, and sediment was diverted north to the Arctic Ocean. Thus, the life span of major transcontinental drainage systems can be comparable to that of the plate boundaries that surround them.

Underground Railroad: Connections to Freedom and Science  

NSDL National Science Digital Library

This 34-minute video is the result of a collaboration between the National Park Service and NASA. It tells the story of the Underground Railroad, the South/North escape routes used by freedom-seeking slaves during the 19th century. Slaves traveling the Underground Railroad, usually on foot, depended on celestial navigation to find their way northward. They continually looked to the Big Dipper and the North Star for direction. The purpose of this video is to increase student awareness of the Underground Railroad and the role celestial navigation played in the Railroad's success. The video also highlights the importance of modern GIS technology in reconstructing historical topographies and finding the exact route of the Railroad. The video combines historical facts, such as the use of handmade quilts for communication, with topics including mathematics, remote-sensing technology, Earth system science, and astronomy.

Current nitrogen dioxide exposures among railroad workers  

SciTech Connect

As part of a series of epidemiologic studies of the mortality patterns of railroad workers, various air contaminants were measured to characterize the workers' current exposures to diesel exhaust. Nitrogen dioxide (NO{sub 2}), which is a constituent of diesel exhaust, was examined as one possible marker of diesel exposure. An adaptation of the Palmes personal passive sampler was used to measure the NO{sub 2} exposures of 477 U.S. railroad workers at four railroads. The range of NO{sub 2} exposures expressed as the arithmetic average +/- two standard errors for the five career job groups were as follows: signal maintainers, 16-24 parts per billion (ppb); clerks/dispatchers/station agents, 23-43 ppb; engineers/firers, 26-38 ppb; brakers/conductors, 50-74 ppb; and locomotive shop workers, 95-127 ppb. Variations among railroads and across seasons were not significant for most job groups.

Conyza canadensis suppresses plant diversity in its nonnative ranges but not at home: a transcontinental comparison.  

PubMed

The impact of invasive species across their native and nonnative ranges is poorly quantified and this impedes a complete understanding of biological invasions. We compared the impact of the native North American plant, Conyza canadensis, which is invasive to Eurasia, on species richness at home and in a number of introduced regions through well replicated transcontinental field studies, glasshouse experiments and individual-based models. Our results demonstrated mostly negative relationships between C. canadensis abundance and native species richness in nonnative ranges, but either positive or no relationships in its native North American range. In glasshouse experiments, the total biomass of Conyza was suppressed more by species from its native range than by species from regions where it is nonnative, but the effects of Conyza on other species did not show a consistent biogeographical pattern. Finally, individual-based models led to the exclusion of Conyza from North American scenarios but to high abundances in scenarios with species from the nonnative ranges of Conyza. We illustrate biogeographical differences in the impact of an invader across regional scales and suggest that inherent differences in one specific aspect of competitive ability, tolerance to the effects of other species, may play some role in these differences.

Preliminary Survey of Icing Conditions Measured During Routine Transcontinental Airline Operation  

NASA Technical Reports Server (NTRS)

Icing data collected on routine operations by four DC-4-type aircraft equipped with NACA pressure-type icing-rate meters are presented as preliminary information obtained from a statistical icing data program sponsored by the NACA with the cooperation of many airline companies and the United States Air Force. The program is continuing on a much greater scale to provide large quantities of data from many air routes in the United States and overseas. Areas not covered by established air routes are also being included in the survey. The four aircraft which collected the data presented in this report were operated by United Air Lines over a transcontinental route from January through May, 1951. An analysis of the pressure-type icing-rate meter was satisfactory for collecting statistical data during routine operations. Data obtained on routine flight icing encounters from.these four instrumented aircraft, although insufficient for a conclusive statistical analysis, provide a greater quantity and considerably more realistic information than that obtained from random research flights. A summary of statistical data will be published when the information obtained daring the 1951-52 icing season and that to be obtained during the 1952-53 season can be analyzed and assembled. The 1951-52 data already analyzed indicate that the quantity, quality, and range of icing information being provided by this expanded program should afford a sound basis for ice-protection-system design by defining the important meteorological parameters of the icing cloud.

New regulations on railroad bridge safety: opportunities and challenges for railroad bridge monitoring  

NASA Astrophysics Data System (ADS)

New federal regulations now mandate North American railroad bridge owners to closely assess the structural capacity of their bridges. Consequently, railroad companies are currently looking into developing and exploring monitoring systems for specific bridges, to help them improve and develop bridge safety in order to help comply with this new rule. The first part of this paper explains the significance of the new federal law. The new rule comes from the Federal Railroad Administration (FRA), Department of Transportation (DOT), and it falls under the 49 Code of Federal Regulations (CFR), Parts 213 and 2371. It requires railroad track owners to know the safe capacity of their bridges and to additionally conduct special inspections if either weather or other exceptional conditions make them necessary to ensure safe railroad bridge operations. The second part of this paper will cover past and current studies about the viability of bridge health monitoring, and actual structural monitoring experiences for railroad bridges. Finally, lessons learned from these monitoring examples, as well as recommendations for future applications, are suggested, including wireless monitoring strategies for railroad bridges such as: campaign sensing inspections (periodic monitoring); bridge replacement observations (short term monitoring); and permanent bridge instrumentation (long term monitoring).

Structure of Railroad Valley, Nye County, Nevada  

SciTech Connect

In 1976, the second oil field in Nevada - Trap Springs - was discovered in Railroad Valley. Since then, more than 100 oil wells have been drilled in Nye County, and most of these have been in Railroad Valley. This well-control helped to unravel the complex structure of Railroad Valley and enabled the construction of more accurate maps of this valley than any other. This information can be used to construct models for exploring other valleys in the Basin and Range Province of eastern Nevada. The basic stratigraphy of the valley consists of Paleozoic carbonates and shales overlain by Tertiary volcanics, overlain, in turn, by valley fill. The areal extent of Tertiary volcanics, which can be a good reservoir rock, is controlled by tensional normal faulting and paleotopography. In some areas, these volcanics can be in excess of 5000 ft thick, but absent within a few miles, owing to paleotopography and/or faulting. The Paleozoic rocks are deformed by a pre-basin and range compressional history that folded and faulted them. As a result, the structure within the Paleozoics is more complex. Thrust faulting played an important role in the deformation of these rocks. Crystalline basement rocks can be found juxtaposed between Paleozoic outcrops in the flanks of the valley, and Paleozoic rocks found in well control farther out in the valley. The geothermal history of Railroad Valley plays an important role in constructing a structural map of the valley, taking into account the Mesozoic thrust faulting and Tertiary normal faulting. Air photos, combined with good well control and published reports, assist in mapping the geologic structure in Railroad Valley.

Field testing of prototype systems for the non-destructive measurement of the neutral temperature of railroad tracks  

NASA Astrophysics Data System (ADS)

In both high speed and freight rail systems, the modern construction method is Continuous Welded Rail (CWR). The purpose of the CWR method is to eliminate joints in order to reduce the maintenance costs for both the rails and the rolling stock. However the elimination of the joints increases the risk of rail breakage in cold weather and buckling in hot weather. In order to predict the temperature at which the rail will break or buckle, it is critical to have knowledge of the temperature at which the rail is stress free, namely, the Rail Neutral Temperature (Rail-NT).The University of California at San Diego has developed an innovative technique based on non-linear ultrasonic guided waves, under FRA research and development grants for the non-destructive measurement of the neutral temperature of railroad tracks. Through the licensing of this technology from the UCSD and under the sponsorship of the FRA Office of Research and Development, a field deployable prototype system has been developed and recently field tested at cooperating railroad properties. Three prototype systems have been deployed to the Union Pacific (UP), Burlington Northern Santa Fe (BNSF), and AMTRAK railroads for field testing and related data acquisition for a comprehensive evaluation of the system, with respect to both performance and economy of operation. The results from these tests have been very encouraging. Based on the lessons learned from these field tests and the feedback from the railroads, it is planned develop a compact 2nd generation Rail-NT system to foster deployment and furtherance of FRA R&D grant purpose of potential contribution to the agency mission of US railroad safety. In this paper, the results of the field tests with the railroads in summer of 2013 are reported.

Transcontinental Surface Validation of Satellite Observations of Enhanced Methane Anomalies Associated with Fossil Fuel Industrial Methane Emissions  

NASA Astrophysics Data System (ADS)

A ground-based, transcontinental (Florida to California - i.e., satellite-scale) survey was conducted to understand better the role of fossil fuel industrial (FFI) fugitive emissions of the potent greenhouse gas, methane. Data were collected by flame ion detection gas chromatography (Fall 2010) and by a cavity ring-down sensor (Winter 2012) from a nearly continuously moving recreational vehicle, allowing 24/7 data collection. Nocturnal methane measurements for similar sources tended to be higher compared to daytime values, sometime significantly, due to day/night meteorological differences. Data revealed strong and persistent FFI methane sources associated with refining, a presumed major pipeline leak, and several minor pipeline leaks, a coal loading plant, and areas of active petroleum production. Data showed FFI source emissions were highly transient and heterogeneous; however, integrated over these large-scale facilities, methane signatures overwhelmed that of other sources, creating clearly identifiable plumes that were well elevated above ambient. The highest methane concentration recorded was 39 ppm at an active central valley California production field, while desert values were as low as 1.80 ppm. Surface methane data show similar trends with strong emissions correlated with FFI on large (4° bin) scales and positive methane anomalies centered on the Gulf Coast area of Houston, home to most of US refining capacity. Comparison with SCIAMACHY and GOSAT satellite data show agreement with surface data in the large-scale methane spatial patterns. Positive satellite methane anomalies in the southeast and Mexico largely correlated with methane anthropogenic and wetland inventory models suggests most strong ground methane anomalies in the Gulf of Mexico region were related to dominant FFI input for most seasons. Wind advection played a role, in some cases confounding a clear relationship. Results are consistent with a non-negligible underestimation of the FFI contribution to global methane budgets.; In situ methane concentrations during transcontinental survey Fall 2010.

Visual monitoring of railroad grade crossing  

NASA Astrophysics Data System (ADS)

There are approximately 261,000 rail crossings in the United States according to the studies by the National Highway Traffic Safety Administration (NHTSA) and Federal Railroad Administration (FRA). From 1993 to 1998, there were over 25,000 highway-rail crossing incidents involving motor vehicles - averaging 4,167 incidents a year. In this paper, we present a real-time computer vision system for the monitoring of the movement of pedestrians, bikers, animals and vehicles at railroad intersections. The video is processed for the detection of uncharacteristic events, triggering an immediate warning system. In order to recognize the events, the system first performs robust object detection and tracking. Next, a classification algorithm is used to determine whether the detected object is a pedestrian, biker, group or a vehicle, allowing inferences on whether the behavior of the object is characteristic or not. Due to the ubiquity of low cost, low power, and high quality video cameras, increased computing power and memory capacity, the proposed approach provides a cost effective and scalable solution to this important problem. Furthermore, the system has the potential to significantly decrease the number of accidents and therefore the resulting deaths and injuries that occur at railroad crossings. We have field tested our system at two sites, a rail-highway grade crossing, and a trestle located in Central Florida, and we present results on six hours of collected data.

Genetic Characterization of Human T-Cell Lymphotropic Virus Type 1 in Mozambique: Transcontinental Lineages Drive the HTLV-1 Endemic  

PubMed Central

Background Human T-Cell Lymphotropic Virus Type 1 (HTLV-1) is the etiological agent of adult T-cell leukemia (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). It has been estimated that 10–20 million people are infected worldwide, but no successful treatment is available. Recently, the epidemiology of this virus was addressed in blood donors from Maputo, showing rates from 0.9 to 1.2%. However, the origin and impact of HTLV endemic in this population is unknown. Objective To assess the HTLV-1 molecular epidemiology in Mozambique and to investigate their relationship with HTLV-1 lineages circulating worldwide. Methods Blood donors and HIV patients were screened for HTLV antibodies by using enzyme immunoassay, followed by Western Blot. PCR and sequencing of HTLV-1 LTR region were applied and genetic HTLV-1 subtypes were assigned by the neighbor-joining method. The mean genetic distance of Mozambican HTLV-1 lineages among the genetic clusters were determined. Human mitochondrial (mt) DNA analysis was performed and individuals classified in mtDNA haplogroups. Results LTR HTLV-1 analysis demonstrated that all isolates belong to the Transcontinental subgroup of the Cosmopolitan subtype. Mozambican HTLV-1 sequences had a high inter-strain genetic distance, reflecting in three major clusters. One cluster is associated with the South Africa sequences, one is related with Middle East and India strains and the third is a specific Mozambican cluster. Interestingly, 83.3% of HIV/HTLV-1 co-infection was observed in the Mozambican cluster. The human mtDNA haplotypes revealed that all belong to the African macrohaplogroup L with frequencies representatives of the country. Conclusions The Mozambican HTLV-1 genetic diversity detected in this study reveals that although the strains belong to the most prevalent and worldwide distributed Transcontinental subgroup of the Cosmopolitan subtype, there is a high HTLV diversity that could be correlated with at least 3 different HTLV-1 introductions in the country. The significant rate of HTLV-1a/HIV-1C co-infection, particularly in the Mozambican cluster, has important implications for the controls programs of both viruses.

Ultrasonic measurement of stress in railroad wheels  

NASA Astrophysics Data System (ADS)

The equipment described here generates ultrasonic shear waves using an electromagnetic-acoustic transducer. Precise measurement of the velocity of two orthogonally polarized signals determines the birefringence and allows the calculation of stress. It is necessary to account for the effect of metallurgical texture which can contribute to the birefringence and appear as moderate stress. This system sends a signal through the thickness of a railroad wheel rim, digitizes the first echo, locks onto a cycle, and calculates the time when it crosses zero amplitude. Signal averaging yields the arrival time of a signal at about 90 ?s with a standard deviation of 2-4 ns. In screening the residual stress in the rims of cast-steel railroad wheels, this system has a total error of ~+/-60 MPa; most of this is due to variability of the texture measured in several stress-relieved blocks cut from wheels. The initial measurements were on wheels in which the manufacture had induced known levels of thermal damage. Results from destructive radial saw cuts through the rims allowed qualitative evaluation of the nondestructive measurements. Most components in this equipment are commercially available.

National Geographic Online: The Underground Railroad  

NSDL National Science Digital Library

Just in time to celebrate Black History Month, this multimedia educational Web site from National Geographic offers a diverse set of materials that describe the Underground Railroad, the famed network of individuals who helped transport African-Americans to freedom before the abolition of slavery. Students will want to start by taking The Journey, which, with the aid of visual materials (such as historical photographs of slaves and abolitionists) and audio selections (such as popular spirituals of the day), allows young people to make decisions about what to do in order to reach the North and freedom. Next, visitors can look at a map of the Underground Railroad routes, including those specific to Harriet Tubman. Also, a nice timeline provides some context to the history of slavery in the New World, beginning with the importing of slaves by Spaniards to Santo Domingo in 1501, and concluding in 1865 when slavery was abolished by the passage of the 13th Amendment. The site is rounded out by a number of educational resources for teachers, divided by grade levels.

Proposed Navajo railroad project, New Mexico  

SciTech Connect

An abstract of the draft environmental impact statement of a rail proposal to transport coal from the Burnham mine in New Mexico to southwestern power plants across Navajo lands describes the construction and design of the rail connections. The railroad, to be operated by the Consolidation Coal Company (Consol), would serve new markets that lack dependable, low-cost transportation services. Employment opportunities for Navajo workers and additional revenues will benefit the region. Rights-of-way requirements will disrupt Navajo grazing and cultivated lands as well as cultural sites. There will also be noise pollution and both water and excavation material needs for the construction. The proposal comes under several legal mandates involving water pollution, interstate commerce, rivers, and relocation assistance.

Future fuels and engines for railroad locomotives. Volume 1: Summary  

NASA Technical Reports Server (NTRS)

The potential for reducing the dependence of railroads on petroleum fuel, particularly Diesel No. 2 was investigated. Two approaches are studied: (1) to determine how the use of Diesel No. 2 can be reduced through increased efficiency and conservation, and (2) to use fuels other than Diesel No. 2 both in Diesel and other types of engines. Because synthetic hydrocarbon fuels are particularly suited to medium speed diesel engines, the first commercial application of these fuels may be by the railroad industry.

Philippine Islands: a tectonic railroad siding  

SciTech Connect

In 1976, significant quantities of oil were discovered offshore northwest of Palawan Island by a Philippine-American consortium led by Philippines-Cities Service Inc. This was the first commercial oil found in the Philippine Islands. Other exploration companies had decided that there was no commercial oil in the Philippines. They fell prey to a situation Wallace E. Pratt, who began his career in 1909 in the Philippines, later described: There are many instances where our knowledge, supported in some cases by elaborate and detailed studies has convinced us that no petroleum resources were present in areas which subsequently became sites of important oil fields. Some explorers are blinded by the negative implications of the same knowledge that successful explorers use to find important oil fields. The Palawan discoveries are examples of successful use of knowledge. Recognition that the Philippine Islands are a tectonic railroad siding may be the key to future exploration success. These islands are continental fragments, each with its own individual geologic characteristics, that have moved from elsewhere to their present positions along a major strike-slip zone. Play concepts can be developed in the Philippines for continental fragments in each of the three major present-day tectono-stratigraphic systems that are dominated by strike-slip, but include subduction and extension tectonics, with both carbonate and clastic sediments.

The Blue Comet: A Railroad's Astronomical Heritage  

NASA Astrophysics Data System (ADS)

Between 1929 February 21 and 1941 September 27, the Central New Jersey Railroad operated a luxury passenger train between Jersey City and Atlantic City. Named The Blue Comet, the locomotive, tender, and coaches sported a unique royal blue paint scheme designed to evoke images of celestial bodies speeding through space. Inside each car were etched window panes and lampshades featuring stars and comets. And each coach sported the name of a famous comet on its side; these comets were of course named for their discoverers. Some of the astronomers honored in this unique fashion remain famous to this day, or at least their comets do. The names D'Arrest, Barnard, Encke, Faye, Giacobini, Halley, Olbers, Temple, Tuttle, and Westphal are familiar ones. But Biela, Brorsen, deVico, Spitaler, and Winnecke have now largely faded into obscurity; their stories are recounted here. Although more than sixty years have elapsed since its last run, The Blue Comet, perhaps the most famous passenger train in American history, lives on in the memories of millions of passengers and railfans. This famous train returned to the attention of millions of television viewers on the evening of 2007 June 3, in an episode of the HBO series The Sopranos. This work was supported by a faculty development grant from Valdosta State University.

In this study, we assessed lung cancer mortality in 54,973 U.S. railroad workers between 1959 and 1996 (38 years). By 1959, the U.S. railroad industry had largely converted from coal-fired to diesel-powered locomotives. We obtained work histories from the U.S. Railroad Retirement Board, and ascertained mortality using Railroad Retirement Board, Social Security, and Health Care Financing Administration records. Cause of death was obtained from the National Death Index and death certificates. There were 43,593 total deaths including 4,351 lung cancer deaths. Adjusting for a healthy worker survivor effect and age, railroad workers in jobs associated with operating trains had a relative risk of lung cancer mortality of 1.40 (95% confidence interval, 1.30-1.51). Lung cancer mortality did not increase with increasing years of work in these jobs. Lung cancer mortality was elevated in jobs associated with work on trains powered by diesel locomotives. Although a contribution from exposure to coal combustion products before 1959 cannot be excluded, these results suggest that exposure to diesel exhaust contributed to lung cancer mortality in this cohort. Key words: diesel exhaust, lung cancer, occupational exposure. PMID:15531439

Steam and Electric Locomotives of the New Haven Railroad Digital Collection  

NSDL National Science Digital Library

The Railroad History Collections at University of Connecticut, home of the archives of the New Haven Railroad, makes available these 460 digitized pictures of locomotives and other scenes associated with the railroad. The images were selected from several thousand collected by railroad enthusiast Fred Otto Makowsky during the first half of the 20th century. Probably the easiest way to search the collection is by using Homer, the online catalog of the UConn Libraries; follow the instructions given under "Search the Collection" to use the tool. Because the default display is a brief catalog record accompanied by tiny thumbnail, browsing is a little limited; users can link to larger views of individual images though. In addition to the Makowsky collection, many other railroad resources can be found by following the Railroads Home link, including the Railroad History Collections list, brief descriptions of the many railroad archives at UConn, links to related digital resources, and email to the curator.

Energy Conservation Projects to Benefit the Railroad Industry  

SciTech Connect

The Energy Conservation Projects to benefit the railroad industry using the Norfolk Southern Company as a model for the railroad industry has five unique tasks which are in areas of importance within the rail industry, and specifically in the area of energy conservation. The NIU Engineering and Technology research team looked at five significant areas in which research and development work can provide unique solutions to the railroad industry in energy the conservation. (1) Alternate Fuels - An examination of various blends of bio-based diesel fuels for the railroad industry, using Norfolk Southern as a model for the industry. The team determined that bio-diesel fuel is a suitable alternative to using straight diesel fuel, however, the cost and availability across the country varies to a great extent. (2) Utilization of fuel cells for locomotive power systems - While the application of the fuel cell has been successfully demonstrated in the passenger car, this is a very advanced topic for the railroad industry. There are many safety and power issues that the research team examined. (3) Thermal and emission reduction for current large scale diesel engines - The current locomotive system generates large amount of heat through engine cooling and heat dissipation when the traction motors are used to decelerate the train. The research team evaluated thermal management systems to efficiently deal with large thermal loads developed by the operating engines. (4) Use of Composite and Exotic Replacement Materials - Research team redesigned various components using new materials, coatings, and processes to provide the needed protection. Through design, analysis, and testing, new parts that can withstand the hostile environments were developed. (5) Tribology Applications - Identification of tribology issues in the Railroad industry which play a significant role in the improvement of energy usage. Research team analyzed and developed solutions which resulted in friction modification to improve energy efficiency.

Development of university-industry partnerships in railroad engineering education  

NASA Astrophysics Data System (ADS)

Rail transportation has been an important part of the North American transportation network since the 19th century and it continues to be a major contributor to the economic well-being and the global competitiveness of the U.S. The recent expansion in freight rail volumes and forecasts for continuous growth, together with more favorable attitudes for urban passenger rail present several challenges for the rail industry. One of the challenges is the availability of a well educated engineering workforce. The rail industry has recognized a need to attract new railroad professionals from various disciplines for management and technical positions, but most universities eliminated railroad engineering from their curricula after the recruitment levels faded several decades ago. Today, railroad expertise and related engineering courses exist at only a few universities and most students graduate without any exposure to rail topics. While industry representatives have expressed their concern about a future workforce, little data is available on the extent of the demand, on the characteristics and skills of preferred candidates, and on the role that universities can play. A benchmarking study was undertaken to investigate the demand for university engineering graduates and assess whether current methods are sufficient to attract, educate, recruit, train and retain engineering students in the railroad profession. Data was collected from industry human resources and training managers to define the quantitative and qualitative needs for railroad engineers. In addition, recently hired engineers working in the rail industry were surveyed to determine the extent of their university exposure in rail topics and how it affected their career choice. The surveys indicated an increase of over 300 percent in the annual recruitment for railroad engineers by the participating companies between 2002 and 2005. Recruitment levels are expected to remain high for the next five to ten years due to high demand for rail transportation and an older engineering workforce with the greatest demand for civil, electrical and mechanical engineers with bachelor's degrees. The rail industry and universities have grown apart over the past several decades, as rail programs and courses were abandoned at universities and there were very limited recruitment and research activities by the railroads at universities. Today, specialized course(s) in rail topics are offered at approximately three percent of ABET accredited civil engineering programs in the U.S. and only 16 percent of engineers who responded to the survey had received university exposure to rail topics. The research findings suggest that increased university participation has the potential to assist the rail industry in all aspects related to attracting, educating, recruiting, training and retaining engineering graduates. The primary advantages would be greater industry visibility and student knowledge in rail topics. Increased prior knowledge, on the other hand, improves the effectiveness of industry training programs and offers a potential for sizable training cost reductions. As a final conclusion, the research suggests that the most effective approach for developing future railroad engineers is a balancing act where the responsibilities should be shared by the rail industry and universities based on each others strengths. University participation should include multiple types and levels, including introductory lectures, co-op/internship programs, courses in railroad engineering, and a minor or certificate in railroad engineering that would include several courses. Due to the urgent demand for railroad engineers and time it takes to rebuild the expertise on campuses, the development process should begin immediately, be incremental, and utilize concepts, such as cooperation with other universities or engineer-in-residence, that reduce the demand of internal university resources. The challenges to the process, such as willingness of partners to understand each others needs and motivations for the relations

Occupational safety regulation and economic efficiency: the railroad industry  

SciTech Connect

This thesis develops a cost-benefit model for the railroad industry to estimate the efficient level of disabling injuries across class 1 carriers. The neoclassical cost function and the hedonic wage function serve as the estimating equations for the cost and benefit estimation, respectively. The cost function is fitted to a sample of thirty-five class 1 railroads in 1980. The hedonic wage function is fitted to a sample of 481 railroad industry employees for the same year. The efficient level of 1980 disabling injuries for each railroad is determined by setting the marginal cost (MC) of injury reduction equal to its marginal benefit (MB). In addition, the cost savings accruing to efficient regulatory reform are calculated for each firm as well as the entire industry. A second-best cost-minimizing regulatory policy is also introduced. The cost-minimizing level of injuries and resulting cost savings for individual firms and the total industry are estimated. The results support the prior hypothesis that MC exceeds MB for the vast majority of firms. Substantial cost savings are possible under reformed regulatory policy.

Transcontinental local area network  

NASA Astrophysics Data System (ADS)

The National Radio Astronomy Observatory (NRAO) has facilities at 17 different locations scattered throughout the USA. These vary in size from the major laboratories occupied by research and support staff to the ten individual antennas of the Very Long Baseline Array. As is typical in astronomy, many sites are in remote locations, which are not well served with modern communication capabilities. Until 1996, the NRAO's internal network was achieved via the Internet; most sites simply had a local port to the Internet and the traffic was routed tortuously to the other locations. The burgeoning demand for Internet bandwidth was (and still is) growing faster than the services could be enhanced, and this led to intolerably slow response times and unacceptably low achieved data rates. To solve this problem, the NRAO acquired a frame relay intranet from AT&T to connect ten of its locations. The operating cost is approximately the same as the multiple Internet connections, but with vastly improved throughput and reliability. Recently, the access to the four major sites has been upgraded to support video conferencing.

A mathematical modeling approach to resource allocation for railroad-highway crossing safety upgrades.  

PubMed

State Departments of Transportation (S-DOT's) periodically allocate budget for safety upgrades at railroad-highway crossings. Efficient resource allocation is crucial for reducing accidents at railroad-highway crossings and increasing railroad as well as highway transportation safety. While a specific method is not restricted to S-DOT's, sorting type of procedures are recommended by the Federal Railroad Administration (FRA), United States Department of Transportation for the resource allocation problem. In this study, a generic mathematical model is proposed for the resource allocation problem for railroad-highway crossing safety upgrades. The proposed approach is compared to sorting based methods for safety upgrades of public at-grade railroad-highway crossings in Tennessee. The comparison shows that the proposed mathematical modeling approach is more efficient than sorting methods in reducing accidents and severity. PMID:23253628

Estimation of the diesel exhaust exposures of railroad workers. II. National and historical exposures  

SciTech Connect

The diesel exhaust exposures of railroad workers in thirteen job groups from four railroads in the United States were used to estimate U.S. national average exposures with a linear statistical model which accounts for the significant variability in exposure caused by climate, the differences among railroads and the uneven distribution of railroad workers across climatic regions. Personal measurements of respirable particulate matter, adjusted to remove the contribution of cigarette smoke particles, were used as a marker for diesel exhaust. The estimated national means of adjusted respirable particulate matter (ARP) averaged 10 micrograms/m3 lower than the simple means for each job group, reflecting the climatic differences between the northern railroads studied and the distribution of railroad workers nationally. Limited historical records, including some industrial hygiene data, were used to evaluate past diesel exhaust exposures, which were estimated to be approximately constant from the 1950's to 1983.

Improving an energy harvesting device for railroad safety applications  

NASA Astrophysics Data System (ADS)

Due to hundreds of fatalities annually at unprotected railroad crossings (mostly because of collisions with passenger vehicles and derailments resulting from improperly maintained tracks and mechanical failures), supplying a reliable source of electrical energy to power crossing lights and distributed sensor networks is essential to improve safety. With regard to the high cost of electrical infrastructure for railroad crossings in remote areas and the lack of reliability and robustness of solar and wind energy solutions, development of alternative energy harvesting devices is of interest. In this paper, improvements to a mechanical energy harvesting device are presented. The device scavenges electrical energy from deflection of railroad track due to passing railcar traffic. It is mounted to and spans two rail ties and converts and magnifies the track's entire upward and downward displacement into rotational motion of a PMDC generator. The major improvements to the new prototype include: harvesting power from upward displacement in addition to downward, changing the gearing and generator in order to maximize power production capacity for the same shaft speed, and improving the way the system is stabilized for minimizing lost motion. The improved prototype was built, and simulations and tests were conducted to quantify the effects of the improvements.

Community-acquired methicillin-resistant Staphylococcus aureus in Madrid, Spain: transcontinental importation and polyclonal emergence of Panton-Valentine leukocidin-positive isolates.  

PubMed

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) isolates producing the Panton-Valentine leukocidin (PVL) have been reported worldwide. We describe the molecular characteristics of PVL-positive CA-MRSA strains isolated in Madrid, Spain, and analyze the clinical features of patients infected with these isolates. From 2004 to 2007, we collected 13 PVL-positive MRSA isolates from patients attending to the emergency department. The isolates were genotyped by pulsed-field gel electrophoresis, SCCmec typing, agr polymorphism, and multilocus sequence typing. Susceptibility to 29 antimicrobials was determined by the broth microdilution and by the E-test methods. The isolates belonged to 3 genotypes: ST8-SCCmec IVc (n = 11), ST5-SCCmec IVa (n = 1), and ST80-SCCmec IVc (n = 1). The corresponding agr types were I, II, and III, respectively. Five isolates were resistant to tetracycline and doxycycline, and 1 was resistant to fusidic acid (ST80). The isolates were from children (n = 9) and adults (n = 4), and were associated with skin and soft tissue infections (n = 9), otitis (n = 1), and bacteremia (n = 1). Nine patients were from South America. Our results indicate the transcontinental importation and recent emergence in Spain of PVL-positive CA-MRSA strains belonging to 3 distinct lineages, including 1 predominant (ST8-SCCmec IVc).

TRC Texas Railroad Commission urges continued voluntary gas allocation  

SciTech Connect

TRC (Texas Railroad Commission) urges continued voluntary gas allocation, specifically, continued reliance on natural gas transmission and distribution companies to make voluntary supply allocation during peak periods. The Texas Independent Producers and Royalty Owners Association has supported this policy. According to F. Pitts (Tex. Independent Prod. R. Owners Assoc.), increased natural gas supplies will reduce the likelihood of prolonged periods of allocation. All U.S. oil and natural gas have come from 2% of the country's sedimentary basins, and more than 3 million sq mi, including some areas of special interest, remain untested by drilling.

Death in the desert. The sabotage-derailment of "The City of San Francisco".  

PubMed

The completion of the transcontinental railroad in 1869 was a milestone in American history. Seventy years later in August 1939, the westbound, new Southern Pacific Railroad streamlined passenger train "City of San Francisco," was intentionally derailed at high speed in northern Nevada by saboteurs who had moved a rail out of alignment. This resulted in a spectacular wreck, claiming the lives of 24 passengers and crew. Despite the finding of physical and trace evidence; and lengthy, exhaustive investigations by railroad police, the FBI, and forensic scientists, the perpetrators were never brought to justice. Deaths resulting from vandalism and sabotage are among the least common of railroad-related deaths; however, acts of vandalism and violence including train derailment are increasingly frequent in this country. Law enforcement officers and forensic scientists must be able to place these incidents in their proper perspective and to successfully investigate and solve them by employing all means at their disposal.

A vibration technique for measuring railroad rail stress  

NASA Astrophysics Data System (ADS)

Longitudinal rail stress, related to constrained thermal contractions and expansions, leads to broken and buckled rails, and consequent service delays and derailments. There is a broad consensus on the need for cost-effective and reliable methods for the measurement of rail stress. Vibration techniques for assessing rail stress, based on the effect of longitudinal force on the free vibrations of beams, have long been proposed. It is well understood that compressive stresses decrease the flexural frequencies, while tensile stresses increase them. Past efforts attempting to use this for measurements of stress in railroad rails have failed due to an inability to control or adequately measure other parameters, most particularly the placement and stiffness of the supports. We are developing a new method in which the influence of support parameters should be minimal. Scanned laser vibrometry measurements of vibration fields, followed by a comparison with guided wave theory for the complex cross section of the rail, promises to allow the stress to be determined with the requisite precision. Here we report on the status of this work. [Work supported by Association of American Railroads and the Transportation Research Board.

Trajectory Coordinate Constraints in Multibody Railroad Vehicle Systems  

NASA Astrophysics Data System (ADS)

In this investigation, the formulation of trajectory coordinate constraints in terms of the absolute coordinates is developed for the use in the computer simulations of railroad vehicle system applications. Examples of trajectory coordinate constraints are the specified forward velocity of a vehicle or a wheelset along a curved track or specified yaw angle of a vehicle or a wheelset with respect to a body trajectory coordinate system. The relationship between the trajectory coordinates and the absolute coordinates is defined and then used to write the trajectory constraints in terms of the absolute coordinates at the position, velocity, and acceleration levels. The motion of the trajectory coordinate system can be uniquely defined in the track body coordinate system using the arc-length coordinate defined along the space curve. It is demonstrated that the use of the trajectory coordinates leads to simple linear constraint equations, while the trajectory constraint equations become highly nonlinear functions of the absolute coordinates. This is mainly due to the nature of the nonlinear relationship between the absolute Cartesian and trajectory coordinates. A numerical example is presented in order to demonstrate the use of the proposed formulations in the analysis of multibody railroad vehicle systems.

Characteristics, changes and influence of body composition during a 4486 km transcontinental ultramarathon: results from the Transeurope Footrace mobile whole body MRI-project  

PubMed Central

Background Almost nothing is known about the medical aspects of runners doing a transcontinental ultramarathon over several weeks. The results of differentiated measurements of changes in body composition during the Transeurope Footrace 2009 using a mobile whole body magnetic resonance (MR) imager are presented and the proposed influence of visceral and somatic adipose and lean tissue distribution on performance tested. Methods 22 participants were randomly selected for the repeated MR measurements (intervals: 800 km) with a 1.5 Tesla MR scanner mounted on a mobile unit during the 64-stage 4,486 km ultramarathon. A standardized and validated MRI protocol was used: T1 weighted turbo spin echo sequence, echo time 12 ms, repetition time 490 ms, slice thickness 10?mm, slice distance 10?mm (breath holding examinations). For topographic tissue segmentation and mapping a modified fuzzy c-means algorithm was used. A semi-automatic post-processing of whole body MRI data sets allows reliable analysis of the following body tissue compartments: Total body volume (TV), total somatic (TSV) and total visceral volume (TVV), total adipose (TAT) and total lean tissue (TLT), somatic (SLT) and visceral lean tissue (VLT), somatic (SAT) and visceral adipose tissue (VAT) and somatic adipose soft tissue (SAST). Specific volume changes were tested on significance. Tests on difference and relationship regarding prerace and race performance and non-finishing were done using statistical software SPSS. Results Total, somatic and visceral volumes showed a significant decrease throughout the race. Adipose tissue showed a significant decrease compared to the start at all measurement times for TAT, SAST and VAT. Lean adipose tissues decreased until the end of the race, but not significantly. The mean relative volume changes of the different tissue compartments at the last measurement compared to the start were: TV ?9.5% (SE 1.5%), TSV ?9.4% (SE 1.5%), TVV ?10.0% (SE 1.4%), TAT ?41.3% (SE 2.3%), SAST ?48.7% (SE 2.8%), VAT ?64.5% (SE 4.6%), intraabdominal adipose tissue (IAAT) ?67.3% (SE 4.3%), mediastinal adopose tissue (MAT) ?41.5% (SE 7.1%), TLT ?1.2% (SE 1.0%), SLT ?1.4% (SE 1.1%). Before the start and during the early phase of the Transeurope Footrace 2009, the non-finisher group had a significantly higher percentage volume of TVV, TAT, SAST and VAT compared to the finisher group. VAT correlates significantly with prerace training volume and intensity one year before the race and with 50 km- and 24 hour-race records. Neither prerace body composition nor specific tissue compartment volume changes showed a significant relationship to performance in the last two thirds of the Transeurope Footrace 2009. Conclusions With this mobile MRI field study the complex changes in body composition during a multistage ultramarathon could be demonstrated in detail in a new and differentiated way. Participants lost more than half of their adipose tissue. Even lean tissue volume (mainly skeletal muscle tissue) decreased due to the unpreventable chronic negative energy balance during the race. VAT has the fastest and highest decrease compared to SAST and lean tissue compartments during the race. It seems to be the most sensitive morphometric parameter regarding the risk of non-finishing a transcontinental footrace and shows a direct relationship to prerace-performance. However, body volume or body mass and, therefore, fat volume has no correlation with total race performances of ultra-athletes finishing a 4,500 km multistage race.

Respiratory symptoms and pulmonary function among welders working with aluminum, stainless steel and railroad tracks.  

PubMed

Sixty-four aluminum welders, 46 stainless steel welders, and 149 railroad track welders were investigated regarding respiratory symptoms and pulmonary function (forced vital capacity and forced expiratory volume in 1 s). Referents consisted of nonwelding industrial workers and railroad workers. All groups of welders showed a higher frequency of chronic bronchitis symptoms than their respective referents. Respiratory symptoms were related to ozone concentrations in welders working with aluminum. In stainless steel and railroad track welders respiratory symptoms were related to chromium exposure rather than to total particle exposure. The pulmonary function was not affected in any of the welding groups studied. PMID:3992218

Railroad bridge instrumentation with fiber-optic sensors.  

PubMed

Fiber-optic sensors were installed on fatigue-critical components in the superstructure of a railroad bridge to monitor dynamic strains induced by trains crossing the bridge as well as to detect the onset of cracks. Each fiber Fabry-Perot interferometer (FFPI) strain gage was adhesively bonded to a stainless-steel strip to facilitate all-weather installation on the steel bridge members by spot welding. FFPI strain sensors were also installed on a rail at an approach to the bridge. Electrical resistive strain gages were colocated with the fiber-optic sensors on the bridge for the purpose of performance verification. In addition to the strain gages, fiber-optic continuity sensors for crack detection were bonded to the structure at critical locations. A telemetry system for transmitting the data over telephone lines was also installed at the bridge site. Dynamic response of the fiber-optic strain sensors is comparable with that of the electrical gages, and their performance has not degraded in the year since the initial installation. PMID:18305719

Chronic obstructive pulmonary disease mortality in railroad workers  

PubMed Central

Background There is little information describing the risk of non-malignant respiratory disease and occupational exposure to diesel exhaust. Methods US railroad workers have been exposed to diesel exhaust since diesel locomotives were introduced after World War II. In a retrospective cohort study we examined the association of chronic obstructive pulmonary disease (COPD) mortality with years of work in diesel-exposed jobs. To examine the possible confounding effects of smoking, multiple imputation was used to model smoking history. A Cox proportional hazards model was used to estimate an incidence rate ratio, adjusted for age, calendar year, and length of follow-up after leaving work (to reduce bias due to a healthy worker survivor effect). Results Workers in jobs with diesel exhaust exposure had an increased risk of COPD mortality relative to those in unexposed jobs. Workers hired after the introduction of diesel locomotives had a 2.5% increase in COPD mortality risk for each additional year of work in a diesel-exposed job. This risk was only slightly attenuated after adjustment for imputed smoking history. Conclusions These results support an association between occupational exposure to diesel exhaust and COPD mortality.

Any Way to Run a Railroad: Implications of Dedicated Trains  

SciTech Connect

The DOE recently issued a policy statement that it would use dedicated trains for most waste shipments to Yucca Mountain. Prior uncertainty about use of dedicated trains for Yucca Mountain rail shipments prevented an assessment of the likely impacts. This paper examines the controversy over the use of dedicated trains and evaluates the national impacts of shipping waste to Yucca Mountain using dedicated trains on the Union Pacific's preferred rail system. The national impacts of the routing are reported as route miles through three land use types: Rural, Urban and Census Places. (authors)

Long-range transport its effect on cloud condensation nuclei over the Pacific Ocean  

NASA Astrophysics Data System (ADS)

Dust and anthropogenic emissions from Asia traverse the Pacific Ocean and intercept North America within a week during the spring months when storm and frontal activity is most intense. The Intercontinental Chemical Transport Experiment - Phase B (INTEX-B), which occurred in April 2006, focused on the transport and transformation of gases and aerosols on transcontinental/intercontinental scales. Airborne measurements during INTEX allow nearly complete characterization of the physicochemical properties of aerosol which allow an independent assessment of their mixing states and ability to act as cloud condensation nuclei (CCN). This size- resolved chemical information, in conjunction with measurements of aerosol size distribution, investigates the concept of activation indices, which relate the efficiency of an aerosol to serve as CCN based on the relative amount of water-soluble material. The Pacific Dust Experiment (PACDEX) in April-May 2007 also focused on direct measurements of long-range transport by following the plumes across the Pacific Ocean from Asia into North America, which demonstrated the unique capabilities of the HIAPER platform. During PACDEX, CCN measurements were made with a dual-column CCN instrument. During both experiments, we observed variety of aerosol layers during vertical and horizontal profiles, ranging from aged aerosols from major Asian dust storms to ultra-fine particles from recent nucleation events. Aerosols from a few hours to over a week old were sampled - including similar air masses at different stages during their transport. Aerosol layers observed were found throughout the Pacific Ocean in stratified layers ranging from altitudes of 1000 meters to 9000 meters. Size resolved chemical measurements indicate cloud processed aerosol in the boundary layer and both aged and ultra-fine layers aloft. Aerosols undergoing cloud processing activate close to an ammonium sulfate limit; while those with anthropogenic origins show lower activation efficiency which points to an insoluble or hydrophobic core (i.e., biomass burning or dust) that has been aged by deposition of a water-soluble material. In some flights, the evolution of the aerosols has been identified and changes in aerosol chemistry from aging or cloud processing are likely to have enhanced the cloud nucleating ability of these aerosols as results indicate an increase in soluble mass fraction from ca. 10% to 40%. Mixing states (i.e., internal vs. external mixtures) are important for interpreting the soluble fraction - and single particle analysis will shed light in this area. The results indicate that horizontal mixing during high-altitude long-range transport (above several kilometers) may be more significant than vertical mixing unless vigorous mixing brings the aerosol into the boundary layer.

On-track testing of a power harvesting device for railroad track health monitoring  

NASA Astrophysics Data System (ADS)

A considerable proportion of railroad infrastructure exists in regions which are comparatively remote. With regard to the cost of extending electrical infrastructure into these areas, road crossings in these areas do not have warning light systems or crossing gates and are commonly marked with reflective signage. For railroad track health monitoring purposes, distributed sensor networks can be applicable in remote areas, but the same limitation regarding electrical infrastructure is the hindrance. This motivated the development of an energy harvesting solution for remote railroad deployment. This paper describes on-track experimental testing of a mechanical device for harvesting mechanical power from passing railcar traffic, in view of supplying electrical power to warning light systems at crossings and to remote networks of sensors. The device is mounted to and spans two rail ties and transforms the vertical rail displacement into electrical energy through mechanical amplification and rectification into a PMDC generator. A prototype was tested under loaded and unloaded railcar traffic at low speeds. Stress analysis and speed scaling analysis are presented, results of the on-track tests are compared and contrasted to previous laboratory testing, discrepancies between the two are explained, and conclusions are drawn regarding suitability of the device for illuminating high-efficiency LED lights at railroad crossings and powering track-health sensor networks.

Preliminary characterization of the F-Area Railroad Crosstie Pile at the Savannah River Site  

SciTech Connect

Historical information about the F-Area Railroad Crosstie Pile is limited. The unit is believed to have been a borrow area for earth fill that began receiving railroad crossties during the 1960s. The number of crossties at the unit began to increase significantly in 1984 when major repair of the SRS rail system was initiated. An estimated 100,000 used railroad crossties have accumulated at the unit since 1984. In an effort to determine the impact of the railroad crossties on the environment a total of 28 soil samples were collected from four test borings in March of 1991. Sample depths ranged from ground surface to 21.5 feet. Three of the borings were extended to the water table and groundwater samples were collected, one in an upgradient background'' area, and two downgradient from the unit. Few analytes were reported above detection limits. Test results are summarized in Section 4.0 and analytes not detected are summarized in Appendix A to this report. In three soil samples collected from depths between 10 and 21.5 feet, copper occurred at levels slightly above background. These copper values were detected in the sidegradient test boring and in the two downgradient test borings. Three organic analytes, acetone, pyridine, and Toluene, were reported above detection limits but well below drinking water standards (DWS) in all test borings, including the upgradient boring. Radionuclide activities were reported above background in both soil and water samples from all test borings. There do not appear to be any statistically significant trends in radionuclide activities with depth, or between upgradient or downgradient borings. The analytes detected in the test borings downgradient from the unit cannot be attributed to the railroad crosstie pile as they are not significantly different than the values reported for the upgradient, background test boring.

Financial and physical capacity of the Burlington Northern Railroad to move western coal  

SciTech Connect

Studies conducted by the Department of Energy, the Department of Transportation, and the National Transportation Policy Study Commission (NTPSC) express concern about the ability of railroads both to carry projected coal traffic and to finance physical plant expansion to accommodate additional coal volumes. These studies, along with past experiences, have called into question the overall physical capacity of the Burlington Northern (BN) Railroad to meet future demands for the movement of coal out of its service areas. The conditions under which the BN could or could not meet projected levels of demand were identified. The study has relied upon secondary information provided by the BN and other sources without verifying such data. The achievement of any financial projection may be affected by possible fluctuating economic conditions and depends on the occurrence of future events which cannot be assured. Therefore, actual results achieved may vary from the projections and such variations could be material.

Future fuels and engines for railroad locomotives. Volume 2: Technical document  

NASA Technical Reports Server (NTRS)

The potential for reducing the dependence of railroads on petroleum fuel, particularly Diesel No. 2 was studied. The study takes two approaches: to determine the use of Diesel No. 2 can be reduced through increased efficiency and conservation, and to use fuels other than Diesel No. 2 both in Diesel and other types of engines. Synthetic hydrocarbon fuels, probably derived from oil shale, will be needed if present diesel-electric locomotives continue to be used.

Preparedness of hazardous materials emergencies in railyards: Guidance for railroads and adjacent communities  

SciTech Connect

Railroads are a key part of the distribution system for hazardous materials and, thus, much hazardous material passes through railyards en route to intermediate or final consumers. While the vast majority of these materials are shipped without incident, both the number of shipments and the nature of the materials themselves dictate that railyards and surrounding communities be prepared to respond quickly and effectively to emergencies. This report contains information on 11 emergency preparedness functions and 150 guidance recommendations.

Ultrasonic measurement of stress in railroad wheels and in long lengths of welded rail  

NASA Technical Reports Server (NTRS)

The failure of high speed emergency braking is discussed for railroad wheels and track. It is shown that high compressive residual stresses exist in the rims of new wheels which generate excessive heat, reducing the stress levels. Thermal stresses that build up in continuous lengths of welded track are reported and nondestructive methods of measuring stresses in thick steel are presented for identification, replacement, or adjustment before hazardous failures occur.

Railroad track monitoring using ground-penetrating radar: simulation study and field measurements  

NASA Astrophysics Data System (ADS)

The subsurface conditions of a railroad track bed have a significant influence on track performance. The depth of the ballast, subballast, and subgrade layers, as well as the presence of water pockets, slurry and other foreign materials all affect track performance. Railroad tie integrity is also an important factor that needs to be monitored for optimum track performance. The possibility of using ground penetrating radar (GPR) to monitor various track parameters in a rapid, synoptic, and non-destructive manner is shown in several simulations presented in this paper. The pulse radar simulations are performed at two different frequencies (100 MHz and 400 MHz). The choice of the two frequencies is dictated by the combined need to perform high resolution probing near the surface (400 MHz), and to probe deeper into the substructure, albeit at lower resolution (100 MHz). The results of the simulation show that the 400 MHz system is better able to estimate the depth of the subsurface layers better than the 100 MHz system. Also, the higher resolution of the 400 MHz system makes it better suited to determine the condition of ties near the surface of the rail bed. However the 100 MHz system is able to better identify anomalies, such as water pockets at deeper depths, compared to the 400 MHz system. Preliminary field experiments at various test tracks also support the above conclusions. It is therefore recommended that a combination of GPR systems at both low and high frequencies be used for optimal monitoring of railroad bed and track condition.

Estimation of the diesel exhaust exposures of railroad workers. I. Current exposures  

SciTech Connect

As a part of a series of epidemiological studies of railroad workers, measurements were made to characterize workers' exposures to diesel exhaust. Since diesel exhaust is not a single compound, an exposure marker was sought. The personal exposures to respirable particulate matter (RPM) of over 530 workers in 39 common jobs were measured in four U.S. railroads over a three-year period. Significant amounts of cigarette smoke (20-90%) were found in many of these samples. Therefore, the respirable particulate concentration, adjusted to remove the fraction of cigarette smoke (ARP), was chosen as a marker of diesel exhaust exposures. The geometric mean exposures to ARP ranged from 17 micrograms/m3 for clerks to 134 micrograms/m3 for locomotive shop workers. Significant interrailroad variations were observed in some job groups indicating that the different facilities, equipment, and work practices found among the railroads can affect a worker's exposure to diesel exhaust. Climate was also found to have a significant effect on exposure in some job groups.

Late Pliocene equatorial Pacific  

NASA Astrophysics Data System (ADS)

Late Pliocene foraminiferal Mg/Ca and ?18O records from Ocean Drilling Program Hole 806B in the western equatorial Pacific (WEP) reveal warm pool climate evolution during the onset of Northern Hemisphere glaciation, 3.1-2.3 Myr B.P. Mg/Ca data indicate an average late Pliocene sea surface temperature (SST) of 27.8°C, a small long-term cooling of 0.3°C between 3.1 and 2.3 Ma, and a glacial-interglacial (G-I) SST range of 2°C throughout this time interval. For comparison, Pleistocene SSTs at this site over the last 0.9 Myr average 27.7°C with a G-I range of 3°C. Orbital-scale variability in Hole 806B SSTs during the late Pliocene occurs predominantly at ˜100 ka, in contrast to foraminiferal ?18O records, which show a dominant 41 kyr period. Variability at a 41 kyr period, out of phase with local annual insolation changes driven by obliquity, is also observed in the new WEP SST record. The WEP SST record suggests that an ˜3°C equatorial Pacific SST zonal gradient prevailed during the late Pliocene, compatible with a weaker Walker circulation. Adjustment of Hole 806B SSTs for past changes in seawater Mg/Ca suggests that SSTs higher than 30°C prevailed at 3 Myr B.P., followed by a progressive cooling of the warm pool through the late Pliocene. The characteristics of late Pliocene tropical climate evolution suggest that atmospheric greenhouse gas forcing played a major role in driving the observed G-I SST changes.

Finite Element Modeling of the Bulk Magnitization of Railroad Wheels to Improve Test Conditions for Magnetoacoustic Residual Stress Measurements  

NASA Technical Reports Server (NTRS)

The magnetoacoustic measurement technique has been used successfully for residual stress measurements in laboratory samples. However, when used to field test samples with complex geometries, such as railroad wheels, the sensitivity of the method declines dramatically. It has been suggested that the decrease in performance may be due, in part, to an insufficient or nonuniform magnetic induction in the test sample. The purpose of this paper is to optimize the test conditions by using finite element modeling to predict the distribution of the induced bulk magnetization of railroad wheels. The results suggest that it is possible to obtain a sufficiently large and uniform bulk magnetization by altering the shape of the electromagnet used in the tests. Consequently, problems associated with bulk magnetization can be overcome, and should not prohibit the magnetoacoustic technique from being used to make residual stress measurements in railroad wheels. We begin by giving a brief overview of the magnetoacoustic technique as it applies to residual stress measurements of railroad wheels. We then define the finite element model used to predict the behavior of the current test configuration along with the nonlinear constitutive relations which we obtained experimentally through measurements on materials typically used to construct both railroad wheels and electromagnets. Finally, we show that by modifying the pole of the electromagnet it is possible to obtain a significantly more uniform bulk magnetization in the region of interest.
