ABSTRACT:
A track renewal train includes a semi-trailer work car which carries track renewal equipment and includes two selectively usable undercarriages for supporting the rear end of the work car. One of the undercarriages is an off-track track-laying bogie supporting the work car on the trackless section where track renewal is effected and the other undercarriage is a vertically movable on-track bogie. A selectively usable on-track bogie supports the forward end of the work car when it is linked thereto, the forward work car end being linked to the last car of the train during track renewal operations.
