Analysis of Findings of Four Tank-Car Accient Reports

A comprehensive overview of the findings and metallurgical analyses of tests conducted at the National Bureau of Standards on samples of tank-car materials submitted by the Federal Railroad Administration is presented. The submitted samples were taken from tank cars which had been involved in...

A Metallugical Analysis of Eleven Steel Plates Taken from a Tank Car Accident near Callao, Missouri

A metallurgical analysis of eleven steel plate samples designed as Callao samples K-1, K-2, K-3, and K-5 to K-12 was requested by the Bureau of Railroad Safety, Federal Railroad Administration, Department of Transportation. The Callao samples were removed from a tank car numbered GATX 94451...

Hazardous Materials Tank Cars- Evaluation of Tank Car Shell Construction Material

A metallurgical analysis of a steel plate sample (the Bell sample) was requested by the Federal Railroad Administration. The steel sample was taken from a tank car (number 88300) which had been involved in an accident near Bell, West Virginia. An investigation was conducted at the National...

Cost/Benefit Analysis of Thermal Shield Coatings Applied to 112A/114A Series Tank Cars

A cost benefit analysis of thermal shield coatings on hazardous material tank cars is performed.

Railroad Tank Car Fire Test: Test No. 6

The Department of Transportation is conducting an extensive research program designed to develop methods to minimize personal injury and damage to property caused by fire from ruptured railroad tank cars filled with hazardous materials. The Ballistic Research Laboratories were requested by the...

Development of a Computer Program for Modeling the Heat Effects on a Railroad Tank Car

A mathematical model has been programmed in FORTRAN IV that represents the response to a fire environment of a railroad tank car laden with a volatile, flammable fluid. Inputs to the program include total mass of lading per foot of tank length, tank length, number and flow area of relief valves...

Safety of High Speed Guided Ground Transportation Systems: Human Factors Phase I - Function Analyses and Theoretical Considerations

Although the speed of guided ground transportation continues to increase, the reaction time as well as the sensory and information processing capacities of on- and off-board operators remain constant. This report, the first of two examining critical human factors issues in future high-speed rail...

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

Issues in Locomotive Crew Management and Scheduling

This study explores matters related to the scheduling and management of locomotive crews, particularly as they might contribute to fatigue and stress. It describes how crews are scheduled currently. why there is so much unpredictability in schedules, how various aspects of current practices...
