In a method for renewing a track (2) and cleaning a ballast bed (3), the old track (2) is lifted off the ballast bed in sections as a track panel (15), transported forward in a working direction (4) and deposited on track panel wagons (8). The exposed ballast bed (3), forming a renewal gap (17), is cleaned by a cleaning machine (11), spoil (32) accruing in the process is transported forward underneath the track panels (15) deposited on the track panel wagons (8), and stored in hopper cars (10). New rails (29), pre-deposited underneath new sleepers (27) positioned on sleeper wagons (14), are pulled forward into the renewal gap (17) by the cleaning machine (11) and deposited on the cleaned ballast bed (3). The new sleepers (27) are laid down on the cleaned ballast bed and connected to the new rails (29) lifted off the ballast bed (3).

A machine having a ballast take-up device for taking up ballast located underneath a track. The take up device has an endless clearing chain guided in a chain channel. In a connecting joint from a transverse channel to a transport channel. There is also a ballast deflector blade pivotable about a pivot axis. Arranged on the ballast deflector blade is a ballast conveyor, designed for ballast transport in the direction towards a pivot axis by means of a conveyor drive. With this, it is possible to expand the operating range of the ballast take-up device, as needed.

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.

A machine having a ballast take-up device (5) for taking up ballast located underneath a track has an endless clearing chain (8) guided in a chain channel (14). In a connecting joint (18) from a transverse channel (15) to a transport channel (17), a ballast deflector blade (20) pivotable about a pivot axis (19) is fastened. Arranged on said ballast deflector blade (20) is a ballast conveyor (24), designed for ballast transport in the direction towards a pivot axis (19) by means of a conveyor drive (23).
