A simulation analysis of train rescheduling strategies on Chinese passenger dedicated lines

Train rescheduling plays a vital role in railway operation. Many factors should be considered in the train rescheduling process and train class, delayed time, remaining distance and current position are the most common ones. There are usually different measures aiming at corresponding factors and combinations of the measures with different priorities compose various train rescheduling strategies. Furthermore, different strategies lead diverse results and they are applicable to various scenarios respectively. This paper researched the effects of different train rescheduling strategies in the background of Wuguang passenger dedicated line by means of simulation experiments. It analyzed class-based strategies first and achieved the suitable strategy and its related parameters. Then it analyzed the influence of different combinations of high-speed strategies and middle-speed strategies under different perturbation scenarios.
