Abstract
The railway infrastructures have been rapidly developed around the world in the
recent years. As a consequence, topology structures and operation modes of the railway network
are greatly changed to very complicated network systems. Reliability analysis of a railway
network combining topology structures with operation functions will help to optimize the
railway network infrastructures. This paper presents a new reliability analysis method of the
railway network, combining the physical topology with operation strategies. Firstly, two
network models of railway physical network and train flow network are proposed. Then key
stations identification indexes can be gained from such two network models, which include
degree, strength, betweenness clustering coefficient and a comprehensive index. Given the key
stations, railway network efficiency can be analysed under selective and random modes of the
stations failure. A real-world case study of the high-speed railway network in China is presented
to demonstrate the key stations playing an important role in improving the whole network
reliability. In the end, some recommendations are given to improve the network reliability. The
proposed method can provide useful information to railway developers, designers and engineers
in the railway infrastructure projects for sustainable development.
