Metro is a safety-critical urban infrastructure, and large cities depend heavily on their metro systems to alleviate traffic jam, while disruptive incidents or accidents have become more frequent, causing threats to passenger safety and transport service. Previously, metro companies were busy in solving the disruptions caused by equipment failure or external disturbances, and the failure process research has not received enough attention, so it is hard to illustrate the route of failure propagation. In this paper, a failure mapping model is proposed to depict the fault-to-incident propagation path. Besides, the research also introduces a method of locating the fault faster by checking the troubleshooting card of each fault propagation point. Then, a case study of Beijing Metro Line 5 is used to demonstrate the effectiveness and feasibility of the model. The systematic explanations of metro operational incidents and disruptions might help understand metro incidents and give possible solutions to improve the resilience of the metro system. This paper would be constructive for dealing with operational disruption.
