In an aspect, a track maintenance vehicle includes a body, a work head, and a controller. The work head performs track maintenance and is coupled to the body. The controller is configured to operate the vehicle in an autonomous mode. In another aspect, an anchor adjustor includes first and second jaws and an actuator. The jaws pivot about a single axis. The actuator causes the jaws to rotate about the axis. In another aspect, an anchor adjustor assembly includes a first pair of jaws, a second pair of jaws and an actuator. The first and second pairs of jaws open and close about a rail in a track. The actuator causes the closed first pair of jaws to translate towards the closed second pair of jaws along a longitudinal direction of the rail.

Track maintenance apparatus and method

A drone vehicle for performing maintenance on a railway system is provided. A drone vehicle control system is structured to utilize tie position data to position a drone vehicle workhead over at least a portion of a respective tie. The drone vehicle control system is further structured to actuate the drone vehicle workhead. The drone vehicle may be controlled by a drone vehicle control system linked, preferably by wireless communications, to a lead vehicle and a lead vehicle control system. The lead vehicle control system and the drone vehicle control system are structured to communicate with each other, with the lead vehicle control system providing the tie position data to the drone vehicle control system.
