Emergencies in the railway network may disrupt high-speed train operations and cause delays. Therefore, it’s critical to shorten the train delay time by adjusting the arrival-departure track operation scheme under emergency conditions. In order to ensure train safety, with the objective of minimizing the delay time and the adjustment complexity of arrival-departure track operation, the article establishes a real-time adjustment and optimization model of arrival-departure track operation under emergency conditions. In algorithm design, genetic simulated annealing algorithm is used to solve the problem quickly and with high quality. The experimental results show that the adjusted train delay time and arrival-departure track occupancy coefficient are low, which can meet the demand of real-time operation adjustment of arrival-departure track of high-speed railway station under emergency conditions.
