This report presents the results of a study to evaluate the aerodynamic (air velocity and pressure) effects of the new high-speed trains on the safety and comfort of people and the impacts on physical facilities in and around Northeast Corridor stations. This report focuses particularly on the...
This investigation of the tubular-axle/roller-bearing failures experienced with M-2 multiple-unit cars of New York's Metropolitan Transportation Authority was aimed at establishing failure mechanisms, assessing the effectiveness of interim and long-term countermeasures, and determining if the risk...
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...
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...
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...
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...
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...
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...
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...
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...
