Locomotives occasionally work in a specific role, such as:
* '''Train engine''' is the technical name for a locomotive attached to the front of a railway [[train]] to haul that train. Alternatively, where facilities exist for [[Push-pull train|push-pull]] operation, the train engine might be attached to the rear of the train;
* [[Pilot engine]] – a locomotive attached in front of the train engine, to enable [[double-heading]];
* [[Banking engine]] – a locomotive temporarily assisting a train from the rear, due to a difficult start or a sharp incline gradient;
* [[Light engine]] – a locomotive operating without a train behind it, for relocation or operational reasons. Occasionally, a light engine is referred to as a train in and of itself.
* [[Station pilot]] – a locomotive used to [[Shunting (rail)|shunt]] passenger trains at a [[railway station]].
