Following operational interruptions in the urban rail transit system, affected trains are typically organized to perform turn back operations at stations with turn-back capabilities, aiming to minimize the impact of the interruption on the network. Considering potential interruptions in the urban rail transit network, this paper presents a method for selecting turn-back stations during the network planning and construction phase to optimize the network structure and enhance resilience. With the uncertainty of interruptions in the urban rail transit network in mind, a stochastic optimization model is formulated in this paper, with the objective of maximizing the expected network performance under various interruption scenarios. The aim is to select the positions of a limited number of turn-back stations in the network so that the network can maintain a high level of resilience in possible interruption scenarios. The number of passengers transported on the shortest path is utilized as the performance metric for the urban rail transit network. Finally, a case study is conducted using part of the Beijing subway network as an example. The result indicates that the resilience of the urban rail transit network is increased by 7.12% compared to traditional methods by the proposed approach in this paper.
