Abstract: In order to implement efficient and safe transport for Urban Transit, this paper put forward a method of drawing up train timetable which was suitable for it. The data such as the start-time and the end-time were stored in XML format and then parsed by the TinyXml which was very convenient and efficient. The parsed data were used on the train simulated the running process. The timer was used to ensure the latest data. In the paper, the software implemented process of train simulated running was introduced in detail by using program flow chart and VC + +6.0. It was implemented the checking and transferring about train timetable and command between ATS and interlock system.
