A rail tie plate retaining workhead is provided for use in conjunction with a rail tie replacement machine moving along a railroad track having a pair of rails. The workhead includes a workhead frame configured for movement along the track relative to the rail tie replacement machine, and a pair of plate retaining frames, each frame associated with a respective one of the rails, and being connected to the workhead frame. Each plate retaining frame has at least one rail guide wheel connected to the retaining frame using a fluid powered cylinder, the wheels vertically reciprocating between an extended position, in which the workhead is raised to a travel position, and a retracted position, in which the workhead is lowered to a working position in operational relationship with at least one targeted rail tie plate.

A tamper drive includes a wobble shaft rotatable about a central axis. The wobble shaft includes an eccentric hub recess within a movable bearing coupled to a yoke. The movable bearing rotates when the wobble shaft rotates to induce reciprocal movement of the yoke. In another tamper drive, an eccentric portion of a wobble shaft is rotatable within a bearing coupled to or integrated with an offset lobe having a pin slidingly disposed therein. Still another tamper drive includes an arm having a shaft fixedly coupled to one end, and first and second cam followers disposed at the other end. A rotatable cam provides a cam surface for each of the first and second cam followers.

A rail maintenance anchor spreader/squeezer work head includes a work head frame, a pair of sliding brackets laterally reciprocating on the frame, each bracket having an anchor engaging end, and a pair of opposed fluid power cylinders secured to the frame, each cylinder connected to a respective one of the sliding brackets for laterally reciprocating the sliding brackets for any one of anchor squeezing, when both cylinders are extended, and anchor spreading when at least one of the cylinders is retracted.
