Traction controller is one of the core components of rail transit trains. The test of traction controller is taken more and more attention in the development process. It is an economical and effective way to construct the test environment of the traction controller by using the modern simulation technology. This paper discusses the design and implementation of semi-physical simulation platform of locomotive, high-speed EMUs, light rail and subway.Firstly, paper describes the development of simulation technology and its applications in the field of rail transportation. Then on the basis of careful analysis of the functional requirements of the simulation platform, the model types and their relations involved in the vehicle simulation experiment were determined. The overall architecture of the distributed simulation platform is planned.，also a variety of experimental scenarios and experimental procedures are planned. For the follow-up platform to achieve the hardware selection, IO conditioning system design and experimental management software and other items of development has laid a foundation.The hardware system of the simulation platform is built on the basis of the real-time simulation computer, The principle of selecting the real time simulation computer and the planning and design of IO signal conditioning system are describedThe model of the simulation platform is built based on MATLAB/Simulink, The simulation models include power electronics, mechanical dynamics and network communication.
