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...
The thermodynamic properties of propane, propylene, n-butane and ethylene were calculated and are presented in tables. The tables list the values of the specific volume, the enthalpy, then entropy, the specific heat at constant pressure, the specific heat at constant volume and the sonic velocity...
A mathematical model for simulating the longitudinal-vertical motion of railroad cars in impact situations is described in this document. Development and validation of the model was part of a study concerned with the phenomenon of coupler bypass resulting from impact or squeeze. The model...
A 127 kiloliter (33,600 gallon) railroad tank car was instrumented and filled with liquefied petroleum gas. A large JP-4 fuel pool fire then engulfed the tank car, and measurements of temperature, pressure, etc. were recorded as a function of time. After 24.5 minutes, the car failed...
Studies were undertaken to measure the elevated-temperature mechanical properties and to determine the elevated-temperature fracture behavior of selected AAR M128-B steel plates. In addition, the ambient-temperature mechanical properties were measured to determine if the requirements of...
An analysis of the failure of an insulated rail tank car, RAX 202, which had been tested to failure in a fire environment at White Sands Missile Range, New Mexico, was requested by the Federal Railroad Administration, Department of Transportation. The tank car, filled with approximately 33,000...
