Abstract: This is a loader moved by a train to cross over the train to transfer cargo, mail, baggage, express, passenger, or freight containers from and to railway cars in the train. A revolving jib crane or skewed traveling crane with depending parallelogram linkage supports a single or double sided loadspreader which is engaged by the train to swing up to engage and lift the container or its hooks and directs a force to move the loadspreader across the car to lift, push, pull, or roll containers off and on the car simultaneously and unlock and lock containers on the car. It includes side, top, bottom, and end lift loadspreaders. It removes and inserts containers on trains in either direction and moves and turns them to station platforms or interfaces with a conveyor or other vehicle or dumps bulk containers with successive loaders and recrosses the train to return the containers to the same cars or to the starting side of the train. It transfers containers between trains on different tracks.
