In recent years, with the rapid growth of urban population, subway has become one of the main ways of travel for urban residents. Due to the complexity of the rail transit system, the operation efficiency and safety of the subway network will face great challenges when the operation is interrupted by disturbances. Based on this situation, this paper proposes a method of urban rail transit network based on train schedule, adopts the spatial–temporal passenger flow changes of the network as the resilience index of the network, takes Chongqing Metro as an example to analyze the results, and obtains the resilience of Chongqing rail transit system under three different disruption scenarios.
