Abstract
A rail-car positioner comprises a carriage on a track running alongside and parallel to the train track and an elongate arm on the carriage is transversely displaceable to enter between a pair of coupled rail-cars of the train and connect the positioner drivingly to the train. The arm is extended substantially axially, from a retracted position on the carriage, in a preferably generally horizontal first direction to introduce an end of the arm between the pair of rail-cars, and said end is then engaged with the rail-cars' coupling by displacing it in a second direction transverse to the first direction.
