ABSTRACT:
In a rail changing machine which removes old rails, prepares the surfaces of the old ties and lays down new rail, a tie plate pick-up device is arranged to pick up the old tie plates and convey them selectively to a trailing car or to a tie plate positioning and dropping device where they are re-laid on the prepared ties. In the event that the old tie plates are not recycled new tie plates are conveyed to the tie plate dropping device. Permanent magnetic pick-up wheels are used and an electromagnetic tie plate holder is used at the dropping station. Problems of lateral alignment at both the pick-up and drop stations and tie plate orientation and longitudinal alignment with the ties at the drop station are overcome using novel mechanisms.
