Based on the complex network theory, the multi-layer network composed of metro networks and inter-city railway networks in city agglomeration is built, and the relative size of maximal connected subgraph, global efficiency and local efficiency are proposed to evaluate the connectivity reliability of the compound rail transit network. Taking the compound rail transit network of Beijing-Tianjin-Hebei urban agglomeration (CRTN-BTH) as an example, this paper will conduct an empirical study, that is, the nodes of the compound network are attacked randomly and selectively to analyze the changes of its connectivity reliability, and to identify the key hub nodes of the network. The simulation results indicate that the CRTN-BTH is not a scale-free network. The connectivity reliability of the compound network is better than that of the selective attack under the random attack, and the key hubs are identified. This study has important practical significance to guide the planning and development of regional rail transit.
