Abstract
Evaluation of railway track reliability is important for the safety and security of railway operation and control of maintenance costs. This paper develops reliability models for railway segment-track systems (RS-TS), including reliability structure models and reliability assessment models. The reliability structure relationships, which include serial structure, quasi-parallel structure, and hybrid structure, among track segments and a track system are analyzed in the reliability structure models. The reliability index of track segments and a serial structure track system is calculated in reliability assessment models with the method of Markov process. It draws on track geometry data and rail wear data from Beijing Subway Line 13 to validate the models.
