A continuously advancing track working machine for compacting ballast comprises a self-propelled machine frame supported by undercarriages on the track for mobility in an operating direction and a track stabilization assembly vertically adjustably mounted on the machine frame between the undercarriages. The track stabilization assembly comprises drives for vertically adjusting the assembly, oscillatory rolling tools arranged for engaging the rails, vibrators for oscillating the rolling tools, and spreading drives for pressing the rolling tools against the gage sides of the rails. Lining drives link the track stabilization assembly to the machine frame for displacing the track engaged by the rolling tools pressed against the track rails in a direction extending transversely to the track, under the control of a lining reference system including a lining reference base, and a measuring device is arranged on the machine frame adjacent the track stabilization assembly for measuring the transverse track displacement relative to the lining reference base into a desired position. |
