Menič smeru jazdy

Menič smeru jazdy (ang. Reverser) je ovládacie zariadenie, typicky páka, ktorá sa používa na nastavenie smeru pohybu hnacieho koľajového vozidla – dopredu, dozadu alebo neutrál. Ten zvyčajne úplne oddeľuje kolesá od hnacieho ústrojenstva. Menič by sa nikdy nemali používať keď je vozidlo v pohybe, aby sa predišlo katastrofálnemu poškodeniu hnacieho ústrojenstva. Z rovnakého dôvodu je zvyčajne potrebné uviesť ovládač výkonu a dynamické brzdy do neutrálneho stavu, aby bol ovládač funkčný.

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.
