Abstract (en)
[origin: EP2020459A1] The method involves detaching and removing a ground layer (6) mechanically below and/or adjacent to a track (1). The ground layer is initially separated from a substrate before mechanically detaching and removing of the ground layer by cutting (5) a base (3) parallel to the rail. The cutting is provided in even-shape, tub-shape, U-shape or in suitable profile form. The track is supported on sleepers (2) on the base. The base is cut by a cutting belt with a saw tooth or with a cutter head and by pressurizing the base with an air jet or water jet. An independent claim is also included for a device for mechanically removing of a ground layer in a railway track.
