Abstract
A train positioning system for moving railroad cars by engaging bogey frames from one side includes a dog carriage guideway spaced from and parallel to a railroad track, a dog carriage mounted to operate along the guideway, a first dog pivotally attached to the dog carriage to pivot in a generally horizontal plane between a retracted position and an extended position. The first dog is positioned to engage a bogey frame in a first direction and be deflected by the bogey frame in a second direction in the extended position. A second dog may be mounted in opposed spaced relation to the first dog also to pivot in a generally horizontal plane between a retracted and an extended position. The second dog is configured to engage a bogey frame in the second direction and be deflected by the bogey frame in the first direction. A system is provided for reversibly operating the dog carriage along the guideway.
