Not usually. Locomotives are built to pull trains, while motorized units often represent inspection cars, maintenance vehicles, speeders, crew cars, or specialty railroad equipment.
Popular examples include speeders, inspection cars, crew cars, motorized handcars, tie-jector cars, fire fighting cars, and maintenance vehicles.
Many do, but compatibility depends on the scale, track system, manufacturer, and model. Always match the unit to the correct scale and power system.
