A cleaning vehicle (1) for cleaning ballast (2) of a track (4) with a rail vehicle (10) has a screening installation (15) provided for the ballast cleaning. A gantry crane (6) mobile on the rail vehicle (10) via crane rails (8) in a longitudinal direction (7) of the vehicle is provided for the transport of the ballast (2) stored in containers (11). Forming a discharge station (12) for discharging the soiled ballast (2), a receiving end (13) of a first conveyor belt (14) is provided, the latter having a discharge end (16) positioned above the screening installation (15). Forming a loading station (17) for discharging the cleaned ballast (2) into an empty container (11), a discharge end (18) of a second conveyor belt (19) is provided, the receiving end (20) of which is associated with an outlet opening (21) of the screening installation (15).

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.

For correction of a track position in connection with ballast cleaning, after cleaned ballast has been returned to a track, the actual position of the latter is measured while determining actual position data. Parallel to that, fixed point correction values are determined by a sighting trolley following behind. The actual position data and the fixed point correction values are transmitted to the tamping machine, following behind, and are used for determining correction values for a desired track position to be created by tamping.
