A second self-propelled vehicle includes a frame whose one end faces one end of the frame of the first vehicle in one of the adjoining track sections, a ballast excavating chain and a conveyor for the excavated ballast. A respective triple-undercarriage arrangement supports the one end of each vehicle frame, each triple-undercarriage arrangement consisting of two on-track undercarriages and an off-track undercarriage. Another undercarriage supports the frame of each vehicle and the distance between the triple-undercarriage arrangement and the other undercarriage supporting each vehicle frame exceeds the length of the assembled track section.
