Metroliner Dynamic Behavior Investigation

The Metroliner cars used in regular rail passenger service on the Northeast Corridor are the subject of a program sponsored by the Federal Railroad Administration, United States Department of Transportation, to improve the ride quality performance of the cars. The technique of mathematical modeling of the car was utilized in this program to predict and postulate methods of obtaining improved performance. The model was generated and verified, and then various parameters were altered to obtain optimum vehicle response. The altered parameters were then used to specify various car component modifications and to generate a specification for a completely new truck.
