Track circuit system is an important basis and core of the train-control system. The performance of the track circuit directly influences transport efficiency and train-operation safety. Accompanied with the constant improvement of the speed, the requirements of the RAMS of track circuit system greatly improved. Given the importance of the track circuit system and the situation of its frequent malfunctions, systematically safety analysis of the track circuit system is very necessary. This paper systematically analyzed the safety of the ZPW-2000A/K track circuit system by safety analysis theory and method. We identified ten top-level hazard events of the system by FFA and FMECA and got all the possible causes and potential consequences of each hazard event by FTA and ETA method. According to the risk-evaluation matrix, we obtained the risk level of each hazard event. It provides the basis for the product design and improvement.
