ABSTRACT:
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 track is raised and ballast is compacted under the points of intersection between the track rails and ties, the ballast being pressed against the held track until it has reached a controlled degree of compaction. Jacking of the track is terminated before tamping.
