ABSTRACT:
New railroad crossties are placed on the rails of a railroad track and pushed along the track by a rail mounted vehicle. When the new crosstie is positioned over a crosstie in the railroad bed that it to be replaced, the ballast at one end of the old crosstie is removed, the rails are urged upwardly to relieve the force on the old crosstie, the new crosstie is then grasped and moved along its length laterally across the track until its trailing end clears the exposed end of the old crosstie, then the new crosstie is lowered and pushed against the exposed end of the old crosstie until the new crosstie pushes the old crosstie out from beneath the rails. A work head assembly is mounted at one end of the vehicle and includes a shovel and clamp assembly, and the work head assembly is movable laterally with respect to the rails of the railroad track to clear the soil away from the ends of the old crossties and to grasp and insert the new crossties beneath the rails.
