The rigid contact network has the characteristics of high security and reliability, low accident rate, small parts, large load volume, and small maintenance workload. It is widely used in ground rice lines. Due to its excellent performance in various aspects, the rigid contact network is currently widely used in most of the underground sections of the domestic subway. Once a rigid contact network accident occurs, it will seriously affect driving efficiency. Innovatively optimize the fault repair process of the rigid contact network, and the driving organization, use the hand to pull the gourd to fix the fault contact network or remove the fault contact network, and then organize the trains into the faulty area to effectively improve the treatment efficiency after the failure. The impact of small faults on the safe operation of the subway.
