An electric locomotive 50 includes a first control line 3f and DC buses 3c and 3d laid between couplers 2c and 2d, a power storage device 61 connected to the DC buses 3c and 3d, and a DC/DC converter 60 that executes charge and discharge control with respect to the power storage device 61. A non-powered vehicle 1 includes DC buses 3a and 3b connected to the DC buses 3c and 3d via a coupler 2a, a second control line 3e, a power storage device 12 connected to the DC buses 3a and 3b via a circuit breaker 5, and a BMU 8 that manages the power storage device 12. The DC/DC converter 60 executes power accumulation control with respect to the power storage device 61 and power accumulation control with respect to the power storage device 12. When having determined abnormality of the power storage device 12, the BMU 8 controls the circuit breaker 5 to be turned off, thereby cutting off electrical connection between the power storage device 12 and the DC buses 3a and 3b. |
