ABSTRACT:
A mobile track leveling, lining and tamping apparatus comprises a frame assembly mounted on undercarriages and mounting a tamping head, a track shifting unit and a reference system for controlling the track leveling and lining by the track shifting unit, and a drive for advancing the frame assembly in the working direction along the track. The frame assembly comprises a main frame and an auxiliary frame mounted on at least one of the undercarriages, one end of the main frame being adjacent one end of the auxiliary frame. A coupling is arranged between the ends of the main and auxiliary frames to permit at least temporary adjustment of the spacing between the frame ends and relative movement between the frames in the working direction. Track surfacing equipment is mounted on the auxiliary frame and the drive comprises a drive for the auxiliary frame. A control is operatively associated with the auxiliary frame drive for selectively driving the auxiliary frame with the main frame and relative to the main frame.
