Disclosed are a rail transit train and a fault protection method thereof. The rail transit train includes two medium voltage power supply buses (A, B), wherein the two medium voltage power supply buses (A, B) are connected through a first contactor (K(III); and when the two medium voltage power supply buses (A, B) both work normally, the power supply capacity and the loads of the two medium voltage power supply buses (A, B) are balanced. The rail transit train can effectively reduce the impact of an interphase short-circuit fault of the medium voltage power bus on an auxiliary power supply system of the entire train, ensure the normal operation of the train in the case of faults, and improve the safety and the operating efficiency of the rail transit train.
