The passenger compartment door is an important part of the train system, the operating reliability of which affects the quality of rail transport system. In this paper, failure mode of the door system is ana-lyzed and the fault tree of the door system is established based on the fault history of the door system from Guangzhou metro line 2. Firstly, door system failure mode is analyzed and the door system failure tree analy-sis was built. Secondly Monte Carlo methods are introduced to simulate the reliability of door system . The results identify the weaknesses in the system and could provide technical support for the reliability design and fault diagnosis.
