Safety of High-Speed Guided Ground Transportation Systems: Shared Right-of-Way Safety Issues

One of the most important issues in the debate over the viability in the United States of high-speed guided ground transportation (HSGGT) systems, which include magnetic levitation and high-speed rail, is the feasibility of using existing right-of-ways. A major potential benefit of shared ROWs...

Fire Safety of Passenger Trains; Phase II: Application of Fire Hazard Analysis Techniques

A comprehensive multi-phase fire safety research program is being conducted by the National Institute of Standards and Technology to demonstrate the practicality and effectiveness of heat release rate-based test methods and hazard analysis techniques when applied to passenger train fire safety. The...

Crashworthiness Design Modifications for Locomotive and Cab Car Anticlimbing Systems

This study addressed the feasibility of incorporating complete anticlimbing systems into both passenger and freight locomotives. Complete systems include pushback couplers, vertically interlocking anticlimber elements, and zones specifically designed to absorb the collision energy. The project...

Safety of High Speed Ground Transportation Systems-Human Factors Phase II: Design and Evaluation of Decision Aids for Control of High-Speed Trains: Experiments and Model

Although the speed of some guided ground transportation systems continues to increase, the reaction time and the sensory and information processing capacities of railroad personnel remain constant. This second report in a series examining critical human factors issues in future high-speed rail...

Passenger Rail Two Car Impact Test Volume III- Test Procedures Instrumentation and Data

A full-scale impact test was performed April 4, 2000 at the Federal Railroad Administration's Transportation Technology Center near Pueblo, Colorado by Transportation Technology Center, Inc., a subsidiary of the Association of American Railroads. The test was performed using two Budd Company...

Safety of Railroad Passenger Vehicle Dynamics: Final Summary Report

This report is a summary of all the work done by Foster-Miller on passenger rail vehicle dynamic safety under the contract awarded by the Federal Railroad Administration. The report presents key issues and findings in the safety assessments and a safety assessment methodology for rail vehicles...

Locomotive Crashworthiness Research: Modeling, Simulation and Validation

A technique was developed to realistically simulate the dynamic, nonlinear structural behavior of moving rail vehicles and objects struck during a collision. A new approach considered the interdependence of the many vehicles connected in typical rail consists. This was accomplished by combining the...

Assessment of Potential Aerodynamic Effects on Personnel and Equipment in Proximity to High Speed Train Operations: Safety of High-Speed Ground Transportation Systems

Amtrak is planning to provide high-speed passenger train service at speeds significantly higher than their current top speed of 125 mph, and with these higher speeds, there are concerns with safety from the aerodynamic effects created by a passing train. Trains operating at high speeds will pass...

Aerodynamic Effects of High-Speed Passenger Trains on Other Trains

With the onset of high-speed train operations in the United States, a study was undertaken to determine the possible aerodynamic effects of these trains have on their surroundings. The aerodynamic interaction between a high-speed train passing other trains, and its effects on the structural...

Non-Accident Release of Hazmat from Railroad Tank Cars: Training Issues

This report presents the results of a study to determine the extent to which written materials used on training railroad hazmat loaders are consistent with reading skills of the trainees. Data from four case study sites was used to conduct the analysis. Each site trains employees to load hazardous...
