Due to unexpected events such as bad weather, unknown object intrusion, train malfunction, etc., the high-speed train arrival or departure time is often delayed, which makes the train unable to operate according to the initial train timetable. At present, the dynamic scheduling problem of high-speed trains under arrival/departure time delay is lack of in-depth analysis, which results in excessive adjustment of the initial train timetable by existing dynamic scheduling methods. This paper aims to establish a delay propagation mechanism model for high-speed train operation based on the Reachable Matrix for the train scheduling problem. Buffer Matrix and the Conflict Matrix are used to analyze the influence range and influence degree on the initial train timetable. The actual operation data of Nanjing South to Cangzhou section is selected to verify the proposed model. The simulation results show that the model can analyze the affected train range and influence degree, which provides scientific basis for the adjustment of high-speed train timetable, and ensure the scheduling plan continuity and stability.
