To improve fuel efficiency while keeping costs low in the case of operating connected electric railcars that are also capable of operation on a single-car basis.SOLUTION: An electric railcar 10 includes an engine unit 103, an electric generator 104, a converter device 105, an auxiliary power supply 107, an inverter device 108, a propulsion motor 109 and an integral control unit 102. The integral control uni 102 stops the engine unit 103 of some electric railcars 10 of a plurality electric rail cars constituting a composition when it is possible to output acceleration and deceleration torques necessary for the composition as a whole even if the engine units 103 of some electric railcars 10 are stopped.SELECTED DRAWING: Figure 1
【課題】一両単位でも運用可能な電気式気動車を連結して運転する場合に、コストの増大を抑制しつつ、燃費効率の向上を図る。【解決手段】電気式気動車10は、エンジンユニット103と、発電機104と、コンバータ装置105と、補助電源107と、インバータ装置108と、推進用モータ109と、統合制御部102と、を備え、統合制御部102は、編成全体で必要な加減速トルクを、編成を構成する複数の電気式気動車の内の一部の電気式気動車10のエンジンユニット103を停止しても出力可能である場合、一部の電気式気動車10のエンジンユニット103を停止させる。【選択図】図1
