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. The machine further comprises a leveling reference system including a leveling reference base having a leading and a trailing end point in the operating direction, and a measuring axle carrying a pickup indicating the track level measured by the axle, the measuring axle rolling on the track off-center between the reference base end points and rearwardly of the track stabilization assembly. |
