ABSTRACT:
Tie plates are moved between a position on a tie plate manipulator vehicle and a track position, which is under a rail and above a tie. A magnetic wheel is used in conjunction with a rail lifter. The rail lifter lifts the rail while the magnetic wheel installs or removes a tie plate from between a tie and a rail. The vehicle may include another magnetic wheel used for picking up tie plates loosely placed upon ties. A ballast sweeper or broom with a rotary core may be incorporated into the vehicle.
