The model for the temporary rest of train based on the operation adjustment of passenger dedicated line

The temporary rest of train should settle 5 interactive problems, which are the selection of the location for the temporary rest of train, the choice of the train for temporary rest, the arrangement of the joining train, the organization of the passengers' transfer and the EMU allocation after the temporary rest. The mathematical model for the temporary rest of train was established with the train running time (normal and temporary speed limit), the departing time of train from the station, the minimal interval time of the tracing trains, the actual delay time at the terminal station, and the type of the joining train at the departing station as the constraint conditions, and with the minimum total delay time at the terminal station as the objective function. With the method of computer simulation and according to different state of the trains, the model can be solved by iterative calculation. For testing the model, this paper provides a simulation experiment with the test data between Shanghai and Nanjing in the simulation test system of Jinghu high-speed railway. The experiment results indicate that the effect of the train operation adjustment can be remarkably promoted by applying the model for the temporary rest of train to reasonably arrange the joining train and the passengers' transfer based on modifying the initial EMU routing scheme.
