Abstract:

Resiliently biased dogs of a car shifting apparatus are automatically moved by double acting hydraulic cylinders to positions in which the dogs cannot engage any car moving along a predetermined path. When this occurs, movement of the dogs from these non-obstructing positions and movement of barneys, which have the dogs pivotally mounted thereon, along the predetermined path are prevented.
