ABSTRACT:
In a non-stop track leveling and ballast tamping apparatus wherein a machine frame is continuously advanced along a track as successive track sections are lifted for leveling under the control of a reference system, a plow is arranged to move ballast onto the ballast bed below the lifted track sections so that there are formed two elongated raised ballast strips below the track rails and an intermediate strip recessed between the two raised strips. A ballast compactor comprises a chassis supporting a vibrator generating at least approximately horizontal vibrations and a hydraulic load. The chassis has rail engaging and guiding rollers associated with each rail and mounting the chassis for mobility on the track and pressure fluid operated cylinders for continuously laterally pressing the rollers without play against the rail with which it is associated.
