ABSTRACT:
A mobile apparatus for dynamically stabilizing a ballast bed supporting a track at a desired level comprises a reference for determining a deviation of the track grade from the desired level, and at least two track stabilization units spaced from each other in the direction of track elongation. Each unit includes a chassis running on the track rails on flanged wheels, vibrators for imparting at least approximately horizontal vibrations to the track engaged by the flanged wheels, a mechanism for laterally pressing the flanged wheels into play-free engagement with their associated rails, and loads associated with each rail and supplemental to the weight of the apparatus for imparting a pressure to the rails in the direction of the ballast bed whereby the vibrating track is pressed to a lower level.
