With the development of regional integration, suburban railway need to interconnect with national railways and operate networked within itself. Passenger flow in the region show the following trends: increasing cross-line passenger volume, uneven spatial-temporal distribution, and the inability of local trains in meeting fast access needs. To adapt to those trends, the suburban railway need to operate multiple train types, especially express and local trains. In this paper, we take the stopping scheme of express trains as the research object, take the total travel time of passengers and the operation cost of railway enterprises as objectives, establish the optimization model, design an improved ant colony algorithm based on computer simulation, so as to calculate the number of stops and specific stopping station of express trains. Finally, taking Shanghai suburban railway Airport Connecting Line as an example, the optimized operation scheme is running 3 express trains and 6 local trains in peak hour, the stopping station of the express train are SLN, DJQ and PDJC. The total travel time of the optimized scheme is reduced by 1.8% compared with the direct trains, despite the increase in operation cost. The case proves that optimizing the stopping scheme of express trains can save the overall travel time of passengers while meeting the transportation demand, proves the effectiveness of the model and algorithm, improves the service quality of suburban railway.
