Research on Reliability Modeling for Railway Track Facility-Segment-Line Systems

Abstract

Reliability of railway track is important for the safety and security of railway operation and control of maintenance costs. This paper develops reliability models for track facility-segment level and improves reliability models for track segment-line level based on the track segment analysis method. The reliability and failure rates of track facilities, segments and lines, which reflect the health status of railway track, are calculated with the method of Markov chain. The reliability hierarchy models for railway track facility-segment-line systems are formed at last.
