Abstract: This paper discusses the key factors related to the design of multi-train movement simulation for urban rail transit.A simulation system has been developed to apply to multi-train simulation, train traction calculation and scheme evaluation. The system is of good expandability in
that it takes the object-oriented method and modularized design. The paper focuses on the design of the system structure and the calculation model for multi-train movement. As a result of a case analysis based on an actual line, the system proves to be able to analyze safety time interval between two trains, study the interaction of running multiple trains and explore influence of different signal systems on trains movement,etc.

Key words: urban rail transit, multi-train movement, train traction calculation, system structure and design, computer simulation
