ABSTRACT:
A rail car indexer that provides a continuous transfer of the rail car bogeys from one dog to the next without ramming into the rail car axles in either the forward or rearward directions. The rail car indexer includes two parallel linearly offset progressor each of which has a barney and dog attached thereto. A center balance and back pressure bypass valve are used to control the raising of the dogs and to insure that the dogs remain in their lowered position until the proper progressor is ready to begin pulling on the rail car bogey axle. Sensors and a photo eye emitter and receiver coordinate the extension, retraction and transfer of an axle between the progressors.
