Abstract
An apparatus for driving plugs into railway tie holes remaining after the removal of at least one rail and its associated tie plate and rail spikes from the railway ties, includes a vehicle adapted for travel along narrow gauge rails temporarily installed on the ties, or along the standard gauge rails while spanning a rail removed section of the track. Vertically reciprocable tamper plates are mounted on the vehicle frame and are reciprocated by the provision of limit switches on the frame in timed relationship to the rate of travel of the vehicle along the rails.
