Train-to-Train Rear End Impact Tests Volume II: Impact Test Summaries

This final report documents these nine tests. Volume I, Pre-Impact Determination of Vehicle Properties, summarizes the vehicle properties obtained prior to the impact tests. These vehicle properties were used in computer simulation of the impact tests and included weights, pitch moments of inertia...

Selected Topics in Railroad Tank Car Safety Research Volume I: Fatigue Evaluation of Prototype Tank Car Head Shield

The characteristics of a prototype head shield for hazardous material tank cars were evaluated with respect to the maintenance of its structural integrity under normal service conditions. The primary concern was with the resistance to fatigue damage of head shield connections to the tank car. The...

Safety Aspects of New and Untried Freight Cars

Recent research efforts sponsored by the Federal Railroad Administration (FRA) will lead to the development of safety criteria for critical parameters of rail vehicles. Suggested test requirements and limits by which to evaluate the dynamic performance of new vehicles have also been formulated as a...

Safety Manual for FRA Survey Vehicles

The safety rules set forth in this manual govern all FRA Survey Vehicles operated by Ensco, Inc. under contract DOT-FR53-80-C-00015. In addition, these safety rules provide guidelines for all ENSCO employees, FRA personnel, and all other personnel working on or visiting the survey vehicles. This...

Safety of High Speed Ground Transportation Systems: Work Breakdown Structure

This report provides a systems approach to the assessment of high-speed guided ground transportation (HSGGT) safety needs and presents one potential methodology by combining a work breakdown structure (WBS) with an interface evaluation methodology. Through a total system approach, this report ties...

Safety of High Speed Guided Ground Transportation Systems: The Biological Effects of Maglev Magnetic Field Exposures

This report describes selected biological effects on transformed human cell lines and on rats from exposure to simulated maglev magnetic fields (MFs). Rats (n = 6 per group) were exposed at various times throughout the 24-h day to MFs simulating the de and complex ac components of the German...

Safety of High Speed Guided Ground Transportation Systems: EMF Exposure Environments Summary Reports

This paper presents an overview of American exposure assessments for electric and magnetic fields (EMF) in the frequency range from 0 to 3 kHz. The exposure information available is very limited for all but a few occupations and sources of EMF. Much of the exposure assessment done to date has been...

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...
