Railcar mover

A railcar mover (also called a Trackmobile, Shuttle Wagon, or a Shunt Vehicle in Australia, the UK, and in Canada) is a road–rail vehicle (capable of travelling on both roads and rail tracks) fitted with couplers for moving small numbers of railroad cars around in a rail siding or small yard. Vollert has developed an unmanned road-rail remote controlled vehicle VLEX for shunting up to 300 t.
