ABSTRACT:
For the purpose of rehabilitation, a ballast bed of a track is taken up in the form of an upper bed layer by a first clearing device and cleaned. The bulk material accruing in the process is discharged in front of the first clearing device—with regard to the working direction—laterally upon the ballast bed in a bed region. The latter can only be covered by the second clearing device which is configured to be of greater width—with regard to a transverse direction of the track—than the first clearing device. Thus, it is possible to intermediately store bulk material, accruing in a front end region of a machine, on the ballast bed for later use.
