A control unit in a first power conversion apparatus is disposed forward, in the traveling direction, of a heat dissipation unit in the first power conversion apparatus, and increases or decreases electric power to be converted in a conversion unit of the first power conversion apparatus in accordance with at least one of information of a number of other heat dissipation units dissipating heat to the traveling wind and information of a distance to a forwardly adjacent one of the other heat dissipation units in the traveling direction.",
