逆転機

逆転機は、動力車の進行方向 (前進、後進、中立) を設定するために使用される制御装置 (通常はレバー) です。中立状態では通常、車輪を動力伝達システムから完全に分離します。動力伝達システムへの致命的な損傷を避けるため、車両の走行中は決して逆転機を操作しないでください。同じ理由で、逆転機を動作可能にするには、通常、スロットル とダイナミックブレーキを解除する必要があります。

Vehicles equipped with a reverser can run both forward and backward with equal capacity, and are even equipped with lights on both ends for this purpose. Depending on the vehicle design, the only difference when changing orientation can be the driving visibility, and cooling behavior .

Reversers should never be operated when vehicles are in motion, to avoid catastrophic damage to the powertrain . For the same reason, to operate the reverser, throttle and dynamic brakes need to be disengaged.

On steam engines , cutoff is the closest feature to a reverser, albeit with more functionality.

Many vehicles only have one set of controls, facing a particular direction. To drive these vehicles in the opposite direction comfortably, it helps to use the universal control stand , or a locomotive remote controller , if supported.
