Abstract
A method is described for the installation of slab tracks in tunnels, in particular tracks on a slab of concrete, with the optimised design and execution characteristics, and substantially increased performance compared to the normal known methods. The method includes a succession of phases executed in order, with the help of an auxiliary track, Consisting of the design of the construction section, the construction of the railway yards, assembly of the auxiliary track from the evacuation platform, execution of the foundation base, assembly of the track in slabs, transitions from slab track - ballast track, and placement of long bars and welding.
