This report presents the results of phase 2 of the project “On-line high-speed rail defect detection” aimed at improving the reliability and the speed of current defect detection in rails. Ultrasonic guided waves, traveling in the rail running direction, were examined for this task. The advantages...
The specific focus of the 2006 National Hazardous Materials Audit was to determine the level of Class I railroad compliance with the requirements for train placement of hazardous materials shipments and accurate hazard communications information on train consists in the train crews’ possession.
This report covers the theoretical development of the safety state model for railroad operations. Using data from a train control technology experiment, experimental application of the model is demonstrated.
A stochastic model of system behavior is developed which is used to estimate the dynamic...
This report describes a study evaluating the effects of train control technology on locomotive engineer performance. Several types of train control systems were evaluated: partial automation (cruise control and programmed stop) and full automation were compared to manual train control. The study...
