摘要： A railroad car positioning apparatus for positioning a railroad car along a track. The railroad car positioning device apparatus includes a carriage member and first and second dog members mounted on the carriage member. The apparatus includes a device for positioning the dog members and for extending the dog members from the carriage member to an axle height of a railroad car for contacting one of the axles on opposite sides thereof. The apparatus further includes a plurality of hydraulic cylinders for moving the carriage member in a forward or reverse direction to acquire an axle and for exerting a force between one of the dog members and the acquired axle to position the railroad car along the track.
