When a ballast bed is first cleaned, the produced waste material (11) is transported by a conveyor belt system (12) to a discharge point (13) which is arranged directly behind the second clearing device (8) and is discharged, leveled and compressed on the subgrade (14) to create a residue processing layer (15). After applying a geotextile (26), a formation protection layer (24) is formed by supplying gravel (25). |
