Mobile apparatus for continuous track renewal

In a mobile apparatus for the continuous renewal of a track consisting of ties and two rails, which comprises a train of freight cars mounted for continuous movement along a right of way consisting of an old track section, a new track section and an intermediate right of way section wherein the track is renewed, a first section of the train being mounted for movement on the old track section, a second section of the train being mounted for movement on the new track section, and an intermediate train section consisting of a carrier frame and linking the first and second train sections and bridging the intermediate right of way section, the carrier frame having two ends respectively carried on undercarriages respectively running on the old and the new track sections, the carrier frame ends being mounted for pivoting about a substantially vertical axis in a plane substantially parallel to the track, and the train sections carrying equipment arranged to transport old and new ties, to remove old ties from the intermediate right of way section and to lay new ties thereat, and to lift and spread the rails in the intermediate right of way section and to guide the rails substantially without friction:

• the carrier frame consisting of two parts, a substantially vertical pivot coupling the two carrier frame parts together for pivotal movement in a plane substantially parallel to the track, and a device for pivoting the two carrier frame parts in said plane and for fixing the same in selected pivotal positions.
