Abstract: Train running simulation of PDL should possess higher precision in terms of the characteristics as high speed and high precision of passenger dedicated line (PDL). The simulation initialization is one of the key factors to improve precision of train running simulation. This paper proposes a new accurate simulation initialization method based on train performance calculation and rules-reasoning. The main process of the simulation initialization is designed first, and the train’s absolute position is abstracted in the signaling system. Then it put forward plus and minus rules collection, and provides reasoning mechanism. On the basis of the railway organization simulation system of PDL, this paper takes the under-constructing Beijing-Tianjin Passenger Dedicated Railway Line as background. Simulation experiments are respectively carried out using traditional way and accurate simulation initialization method in four-aspect fixed block signaling system and quasi-moving block signaling system. The results indicate that train running simulation precision ADT can be reduced by 23%.
