Abstract
A railway vehicle for inserting plates on rail ties that engage with rails includes a frame configured for movement relative to the track and a plate inserter workhead mounted to the frame. The plate inserter workhead is configured for pivoting the tie plate about a leading edge of the plate so that the trailing edge of the tie plate is lifted off the tie. The plate inserter workhead is configured to subsequently release the plate.
