A railroad vehicle comprising: a first storage battery unit; a first DC-DC converter which is connected to the first storage battery unit; a first DC-AC converter (34A-1, 34A-2) which converts a direct current into an alternating current; a first motor (70A-1, 70A-2) which outputs a driving force to a wheel using an alternating current supplied from the first DC-AC converter (34A-1, 34A-2); a first DC link which connects the first DC-DC converter and the first DC-AC converter (34A-1, 34A-2) to each other and in which a first switch is provided; a second storage battery unit; a second DC-DC converter which is connected to second storage battery unit; a second DC-AC converter (34B-1, 34B-2) which converts a direct current into an alternating current; a second motor (70B-1, 70B-2) which outputs a driving force to the wheel using an alternating current supplied from the second DC-AC converter (34B-1, 34B-2); and a second DC link which connects the second DC-DC converter and the second DC-AC converter (34B-1, 34B-2) to each other and in which a second switch is provided, characterized by a third DC link which connects a place between the first switch and the first DC-AC converter (34A-1, 34A-2) in the first DC link and a place between the second switch and the second DC-AC converter (34B-1, 34B-2) in the second DC link and in which a third switch is provided; and a controller configured to: control the first DC-DC converter such that a voltage of the first DC link approximates a target voltage and control the second DC-DC converter such that a voltage of the second DC link approximates the target voltage; cause the first switch and the second switch to be in a conduction state when no abnormality has occurred in the first storage battery unit, the first DC-DC converter, the second storage battery unit, and the second DC-DC converter; cause the first switch to be in a cut-off state and causes the second switch and the third switch to be in a conduction state when an abnormality has occurred in the first storage battery unit or the first DC-DC converter; and cause the second switch to be in a cut-off state and causes the first switch and the third switch to be in a conduction state when an abnormality has occurred in the second storage battery unit or the second DC-DC converter. a first storage battery unit;
