Key Problems in Train Working Diagram of Passenger Special Line

The train working diagram is the base of railway transportation organization. The research on compilation theories on it is favorable for improving the level of passenger transportation, organization and services. The greater the improvement the more useful it is to increase the benefits for railway transport enterprises. In this paper, the differences between the existing train working diagram and passenger special line rain working diagram are analyzed. The problem of passenger trains departure time distribution is a relatively independent phase in the process of compiling train working diagram, and in the paper, two mathematical models are established for solving trains departure time and distribution problem. The first mathematical model is based on maximizing passenger convenience which is established satisfactorily, by Hungary algorithm which was proposed to solve the problem, for greater feasible solutions. The second mathematical model is based on optimizing, and electric multiple unit (EMU) is selected for better solutions from feasible solutions. The standard transportation network is constructed for solving the second model. The method is proved by an example and is feasible and effective.
