ABSTRACT:
An apparatus for the continuous replacement of track rails comprises a forward and a trailing track renewal vehicle, which may have a common frame. The rails are unfastened and removed from a first track section on which an undercarriage supports the forward vehicle for continuous mobility and the replaced rails are laid in a second track section on which an undercarriage supports the trailing vehicle. A monitoring device is associated with the trailing track renewal vehicle to sense markings on the ties as the trailing vehicle moves along the second track section and to be guided by the markings, the markings indicating the position of the first track section and the monitoring device being arranged to position the rails of the second track section in alignment with the first track section.
