ABSTRACT: A Train Performance Simulator (TPS) is a computer program which simulates the operation of a train over a railway route. It may be used for a variety of purposes to determine the effects of some operational strategy or equipment change upon schedules and energy consumption. The general characteristics of a TPS are discussed, including requirements for route and train input data and fundamentals of the mathematical models available. The USDOT/TSC TPS is a relatively complex, but simple to use, example of a general-purpose TPS. Its features are described and the operating cycle of the program is examined. The mathematical model is discussed in detail. A wide variety of output data may be specified and many output options exist. Instructions for setting up the input data or running the TPS are not given, but samples of output are included.
