Abstract: Aiming at the problem of train failure rescue mode and delay calculation of urban rail transit, the operation process of train failure rescue was firstly analyzed, and then the delay calculation methods of five rescue modes were established according to the operation process. Finally, Open track was used to simulate the train failure rescue of a subway line in Fuzhou, and the simulation and calculation results were compared and analyzed. The research results show that: increasing the rescue speed within a certain range can effectively reduce the operation time of the rescue train; the proposed calculation method can reflect the delay situation more accurately; within the starting and ending points of the rescue, the delay of the later trains running in a fixed block will suddenly increase and accumulate, resulting in the difference of delay increase.

摘要： 针对城市轨道交通列车故障救援方式及延误计算问题，对列车故障救援作业流程进行分析，然后根据作业流程建立5种救援方式的延误计算方法，最后使用Open track对福州市某地铁线路进行列车故障救援仿真，并对仿真与计算结果进行比较分析。研究结果表明：在一定范围内提高救援速度可有效减小救援列车作业时间；所提出的计算方法可较为准确反映延误情况；在救援起讫点内，以固定闭塞运行的后序列车的延误会突增并积累，造成延误增幅的差异。
