ABSTRACT:
A track renewal train of a plurality of track-bound freight cars storing ties removed from an old track section and ties to be laid for a new track section comprises a work car whose front frame end is pivotally supported on a last freight car. Elongated conveyors are mounted on the work car for conveying the old ties from a tie removing device and the new ties to a tie laying device. A tie transfer vehicle has front and rear gantry undercarriages, the front gantry undercarriage being movable only on the last freight car and the rear gantry undercarriage being movable only on the work car. The tie transfer vehicle includes two tie gripping devices arranged successively in the working direction of the train for simultaneously receiving the old ties and delivering the new ties while the ties are positioned transversely to the old track section.
