Nowadays, railway systems are expected to have high reliability, availability, maintainability, and safety. Thousands of ZPW-2000A track circuits are in operation on the mainline and high-speed railway network in China. This paper presents a scheme for reliability assessment of ZPW-2000A track circuit using Bayesian network. First, a fault tree is built based on expert experience and failure investigation...
Condition based maintenance (CBM) is considered to be the most effective maintenance strategy in a performance contract. It significantly increases the system availability and efficiency, meanwhile reduces service affecting faults and maintenance cost, especially when combined with online monitoring of real-time condition data of assets. For the above reasons, CBM has been paid more attention in railway...
