A mobile leveling, lining and ballast packing machine for the non-stop correction of a track comprises a pair of elongated vibratory ballast compacting plates extending along the tie ends at each side of the track and arranged cooperatively to compact the ballast therebetween, a fine correction track lifting and lining unit between the plates, a coarse correction track lifting and lining unit forwardly of the fine correction unit, a first ballast plow and shaping unit associated therewith for moving ballast inwardly from the tie ends during operation of the coarse correction unit, a second ballast plow and shaping unit rearwardly of the fine correction unit, and ballast tampers compacting ballast against the tie ends rearwardly of the second ballast plow and shaping unit. A stationary reference system controls the track correction and includes a series of marker posts mounted along the track, a tensioned reference line supported on the posts, and elements releasably holding the tensioned reference line and for adjusting its vertical and lateral position whereby respective reference line sections may be readily mounted, dismounted and adjusted during movement of the machine. A sensor unit is associated with the correction unit and cooperates with, and senses, the tensioned reference line.
A mobile leveling, lining and ballast packing machine for the non-stop correction of a track consisting of two rails fastened to ties resting on ballast and defining cribs therebetween, the ties having ends projecting laterally from the rails and points of intersection with the rails between the ends, the machine comprising the combination of
