Abstract
A mobile machine for leveling, lining and tamping a track has a heavy main frame supported on undercarriages for continuous movement in an operating direction, a power plant, a drive for continuously advancing the main frame along the track in the operating direction and a brake for stopping the advance of the main frame, the power plant, the drive and the brake carried by the main frame, and a lighter subframe pivotally and longitudinally adjustably connected to the heavy main frame. Tamping heads are mounted on the subframe for tamping ballast in intermittent tamping cycles under respective the ties at points of intersection of the two rails and the ties. A track lifting and lining unit is associated with the two rails mounted on the subframe ahead of the tamping heads in the operating direction, and the tamping heads and track lifting and lining unit being arranged on the subframe between two undercarriages spaced in the direction of the track, one of said undercarriages wherebetween the tamping and track lifting and lining unit is arranged being a further undercarriage supporting the subframe on the track. There is another drive for stop-and-go advancement of the subframe synchronously with the intermittent tamping cycles, and a stop-and-go advancement drive and/or brake arranged to operate on the further undercarriage.
