ABSTRACT:
The present invention comprises a device for automatically inserting wooden railroad tie plugs without the need for multiple crew members of intense labor. The device comprises a feeding mechanism adapted to place a wooden tie plug to be inserted into a gun adjacent a spike hole over a railroad tie. A horizontal positioning ram and insertion tube cooperate to ensure the tie is properly positioned and an attendant vertically mounted ram forces the wooden tie plug into the spike hole, thereby rehabilitating the railroad tie and placing it in a condition for respiking.
