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).

The present disclosure generally relates to a road rail stoneblower vehicle for carrying out rail maintenance operations near fixed structures such as bridges and overpasses. The road rail stoneblower includes a hi-rail chassis having a first set of wheels configured to engage a road surface and a second set of wheels configured to engage surfaces of substantially parallel rails of a railroad track. The road rail stoneblower further includes a plurality of workheads that are capable of dispensing ballast stones into a bed of ballast underlying the railroad track to adjust the height of the rails. The road rail stoneblower further includes a leveling system detachedly coupled to the hi-rail chassis that is configured to transmit a detectable signal that defines a reference plane with which the rails are to be aligned. Related methods of operation of the road rail stoneblower vehicle and associated maintenance of ballast beds underlying railroad tracks are also described.

The present disclosure generally relates to a railroad chassis vehicle having independently operable workheads for carrying out rail maintenance operations on non-uniform sections of railroad tracks. Related methods of operation of the railroad chassis and associated maintenance of ballast beds underlying railroad tracks are also described.
