Abstract: ITCS, which has been successfully applied in China Qinghai-Tibet railway, is one of the modern advanced wireless train control system. In this paper, the system function and structure of on-board control device are introduced. Based on the general procedures of FTA for reliability assessment, with the typical configuration and practical operation process, the fault mode of ITCS are defined and the fault tree is built accordingly, then based on the features of Markov process, the reliability derivation of and gate and or gate are realized for the quantitative calculation of the entire system. Finally, combined with the project implementation, the emergency response policies under certain fault state are detailed analyzed.

Key words: railway transportation, railway signaling, GPS, GSM-R, train control system, ITCS
