Expression system of passenger train plan in high-speed railway

As Beijing-Shanghai high-speed railway will be launched and operated, it is urgent to generate an appropriate passenger train plan, but the methods of drafting and optimizing train plan are very complex and diverse, so providing the train plan with information technology support is becoming necessary, which will effectively help formulating and adjusting train plan. In this paper, the management systems related to the train plan as well as several of its some expression modes are analyzed and researched. Meanwhile, the multi-granularity expression system based on UML high-speed railway train plan is put forward, which can accelerate the modernization of the means of railway management and heighten the organization level in railway transport.
