Reversor

O reversor é um dispositivo de controle, geralmente uma alavanca, usada para definir a direção de movimento de um veículo ferroviário motorizado - para frente, ré ou neutro. O último normalmente separa completamente as rodas do trem de força. O reversor nunca deve ser operado quando um veículo estiver em movimento, para evitar danos catastróficos ao trem de força. Pela mesma razão, o acelerador e os freios dinâmicos normalmente precisam ser desengatados para que o reversor seja operado.

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.
