Train performance simulation is the foundation of DC analysis and transit line operation. The dynamics of rail trains have been studied for a long time and can be described by established equations. Many simulation programs already exist and are used by the academia and the industry. However, there remain some difficulties in implementing train motion equations to computer simulation so far. The program presented in this paper was developed to solve these difficulties. The authors utilize the modulized feature of MATLAB/SIMLTLINK(R) to construct the train motion block diagram in a straightforward drag-and-drop manner. Train motion equations are then solved using the built-in integration methods equipped with the algebraic loop solver to account for the effects of train speed, position, and line voltage. Also traction characteristics can be described by a small number of data points. Moreover, new blocks can be easily added to their program to include ATC and signaling systems, making it a good building block for DC analysis and other transit line operation assessments.
