TRACK SURFACING MACHINE WITH TRACK STABILIZATION A continuously advancing track surfacing machine for compacting a ballast bed comprises a power actuated, vertically adjustable track stabilization assembly mounted on the machine frame between front and rear undercarriages supporting the machine frame on the track. The track stabilization assembly includes rail-engaging vibratory roller tools and a drive for pressing the roller tools into engagement with the facing gage sides of the track rails, and a track leveling reference system monitors the track level. A vertically adjustable plow arrangement for smoothing the ballast bed is mounted on the machine frame between the undercarriages and associated with the track stabilization assembly, the plow arrangement extending across the track at least from one of the tie ends to the opposite tie end. |
