The phenomenon of job-housing separation makes the passenger flow of the fast-track line show obvious tidal characteristics during the peak hours. Considering the scheme of skipping stations for passenger direct-to-city fast-track trains, it is of great significance to optimize the train operation scheme, improve the train service level and meet the passenger travel demand. From the perspective of meeting the travel needs of passengers, this paper takes the overall travel time of passengers, the overall stop time of trains and the shortest total line length of trains as the optimization objectives, constructs a 0-1 integer linear programming model for the periodic skipping of fast rail trains, and uses Genetic Algorithm (GA) to solve the model. The validity of the model is verified by practical examples, and the optimal skipping operation scheme of rail trains is obtained. The results show that the high-speed rail train jump station scheme considering periodic jump station can realize the efficient transportation of large passenger flow at the station. On this basis, the formulation process of train operation diagram and timetable is simplified, which provides a reference for the jump station scheme of large passenger flow trains on holidays.
