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, 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, the flanged wheels and the vibrators being arranged on the chassis to vibrate in unison to transmit the vibration to the track, the 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. |
