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.

Key words: traffic and transportation engineering, urban rail transit, train failure rescue, delay calculation
