The ballast bed fulfils important functions as the binding element between sleepers and substructure. Fouling increases over the years for various reasons. When the necessary good functioning is no longer assured, ballast bed cleaning must be performed.
This work can be performed highly efficiently using ballast bed cleaning machines made by Plasser & Theurer. Thanks to the high working speed of the machines, even short intervals between trains can be utilised. High cleaning quality and the re-use of large quantities of ballast, which is a very costly resource, ensure cost-effectiveness.
