ABSTRACT:
Track rails fixed to ties with old rail fasteners are replaced by track rails fixed to the ties with new rail fasteners at gauge with an assembly line of a series of individual operating mechanisms arranged spacedly and sequentially on a train of a plurality of track-bound cars and including a carrier frame. Each operating mechanism includes vertically movable tools centered over their work and the assembly line comprises, in sequence, a first operating mechanism mounted on the carrier frame for lifting the rails at gauge and for spreading the lifted rails beyond the track gauge after the old rail fasteners have been detached from the ties, the detached rail fasteners leaving holes in the ties, an operating mechanism for plugging the holes in the ties and an operating mechanism for adzing the ties mounted on the carrier frame, an additional operating mechanism mounted on the carrier frame for placing the track rails on the plugged and adzed ties at the gauge, and a further operating mechanism for applying the new rail fasteners to fix the track rails to the plugged and adzed ties.
