ABSTRACT OF THE DISCLOSURE A controlled degree of ballast compaction is obtained with a mobile track tamping and leveling machine which comprises a track holding device holding the track at a leveled position under the control of an error signal from a reference system. The ballast is compacted under the points of intersection between the track rails and ties by a pair of opposed vibratory tamping tools arranged for immersion in the cribs adjacent a tie and for recipro- cation in the direction of track elongation, with the tie positioned between the opposed tools, and an additional vibratory tamping tool arranged for immersion in the ballast adjacent the end of the tie and for reciprocation in a direction transverse to the track elongation. The ballast is pressed against the held track until it has reached a controlled degree of compaction, a control for regulating the compaction degree regulating the drives for reciprocation and vibration of the tamping tools. -1-
