The invention discloses a rail transit vehicle which comprises a vehicle body and an energy-supplying system arranged on the vehicle body. The energy-supplying system comprises a current-collecting device, an energy-storage power source, a traction inverter and a traction motor, wherein the energy-storage power source is provided with a dynamic type super capacitor, at the charging portion of the energy-storage power source, a positive pole of the energy-storage power source is connected with a first power supply rail through the current-collecting device, the negative pole of the energy-storage power source is connected with a second power supply rail through the current-collecting device, or a negative pole of the energy-storage power source is connected with a running rail; the traction inverter is connected with the energy-storage power source, and the traction inverter converts a direct current transmitted from the energy-storage power source into a three-phase alternating current in the operation; the traction motor provides tractive force for a vehicle, the traction motor is connected with the traction inverter, and the traction motor receives the three-phase alternating current sent by the traction inverter in the operation. According to the rail transit vehicle, the problem that electrocorrosion for underground facilities such as pipelines along the rail caused by a current of the running rail of the rail transit vehicle and other problems are effectively solved.
