Based on the open source platform of Microsoft MSTS, a three-dimension simulation system of train operation in Zhengzhou Metro Line 1 was established and the model of ATP safe braking was applied to the 3D simulation. First, the structure and function of the 3D simulation system are introduced. Based on the typical safe braking model defined in IEEE1474. 1 standard, the algorithm of ATP safety braking curve was studied according to a traction calculation of train operation. Then, taking line data in the 3D system as example, the speed control mode curve is simulated and verified, and the ATP＇s over-speed protection function of the train in the 3D simulation system is also realized. Through the combination of train operation control principle and 3D system, the simulation study can improve the authenticity of the 3D simulation and provided a reference for simulation research and test of rail transit control system.
