In a method for stabilizing an earth formation exposed after removal of a track and ballast, in a first working pass in a work section following a rear crawler track with regard to a working direction, parallel to the removal of the ballast the earth formation is loosened up, aggregates are introduced, and grading takes place. In a second working pass, the earth formation to which aggregates have been added is mixed thoroughly by getting picked up by means of a clearing chain and transported onward to a discharge point located behind the rear crawler track and discharged again upon the exposed earth formation, after which, by grading and consolidating the discharged earth formation, a rehabilitation layer is formed.

In a method for restoring, renovating or rebuilding a railway, a substructure or part of a substructure is installed, a track bed is installed and a track grid is installed and/or an existing track grid is extended, an existing track bed is extended and an existing substructure or part of a substructure is extended. There is provision that the installation of the track grid, the installation of the track bed and the installation of the substructure or part of the substructure takes place in a single working process and/or in that the extension of the existing track grid, the extension of the existing track bed and/or the extension of the existing substructure or part of the substructure takes place in a single working process. Track bed material and/or substructure material is transported to the site and/or away from the site by rail.
