abstract="In order to ensure the safety of regional railway transportation and improve emergency response effectiveness of railway network system in disasters, taking Chengdu-Chongqing urban agglomeration as an example, two models of undirected and unweighted railway physical network and undirected weighted railway traffic network were constructed by using complex network theory. Relative size of maximum connected subgraph, network robustness and overall network efficiency were selected to evaluate the dynamic reliability of railway network from two aspects of node failure and side failure. Based on this, a proposal for railway network safe operation planning optimization was put forward. The research shows that the railway network of Chengdu-Chongqing urban agglomeration is robust to random attack and vulnerable to selective attack, and the network connectivity and information transmission efficiency vary significantly under different attacks in the case of network failure. It is also found that Chongqing North Station, Chongqing Station, Chengdu East Station, Chengdu Station, Hechuan Station, Dazhou Station, Chengdu Station-Pengshan Station, Xinjin Station-Xinjin South Station and Xinjin South Station-Pengshan North Station are the key stations and road sections that affect the reliability of the network. © 2019 China Safety Science Journal<p /><p>Language: zh</p>",
