Abstract (en)
The invention is concerned with a method of replacing, in an existing underground, the original track within the tunnel. The old track is removed and from outside the tunnel via a station entrance, separate, prefabricated elongated elements (4) are supplied and installed to bear a running rail (1). Coupling elements (5) are supplied from outside the tunnel and are mounted to the elements (4) to keep them at a mutual distance. The elements (4) contain recesses (6) and the elements (4) are positioned such that the recesses (6) receive the typical radial coupling flanges of the tunnel sections that project inwards from the tunnel wall, such that the elements (4) bear with a large surface area on the tunnel wall.
