Abstract:	In this research, a train simulator (TrainSim) is developed using Object-Oriented Programming (OOP) concepts with C++ language. Two algorithms for generating train speed profiles are embedded in the system. Both generate speed profiles obeying equation of motion and physical constraints of train and railway geometries. The shortest time speed profile generated from TrainSim is compared with a commercial Train Operation Model (TOM). The result shows that the difference is only 0.16%. When compared with manual calculation by the expert from Taiwan Railway Administration (TRA), it is found that the difference in proper operation time between TrainSim and the TRA expert is -0.12% on average. These results demonstrate that the proposed algorithms are robust and efficient, and are very useful and flexible for train operation research and applications.
