Abstract
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.
