ABSTRACT:
A mobile apparatus for replacing an assembled section of track in a track renewal section, the assembled track section consisting of rails fastened to ties defining spaces therebetween, comprises a succession of transport vehicles having undercarriages capable of running on the track for moving therealong, and hoists for gripping and carrying the assembled track section are mounted on the transport vehicles. An elongated overhead girder extends in a plane above the transport vehicles and has longitudinally extending sides defining therebetween a guide track for moving the succession of transport vehicles therealong, and drives move the vehicles along the guide track. A succession of vertically and laterally adjustable supports for the overhead girder are laterally adjustable to selected lateral positions spaced from the girder sides whereby a wide enough space extending transversely to the track is left to permit the free passage of an assembled track switch section carried by the transport vehicles moving along the girder, the supports including power drives for adjusting the supports.
