The results of the screening using ballast cleaning machines made by Plasser & Theurer are excellent as the fine grain proportion is often lower than in new ballast. When working on superelevation in track curves, the screening unit can always be held horizontally with the help of hydraulic cylinders. The placement of ballast

The advantage of ballast cleaning is that it can be done by an on-track machine without removing the rail and sleepers, and it is therefore cheaper than a total excavation. In the 19th century and early 20th century, ballast was shoveled or forked, then screened by hand using portable devices. Early automated cleaners used vacuum pressure built by a steam locomotive to suck ballast up from the track to feed

Ballast materials form a layer which encases the sleepers to provide both vertical and transversal stability to rail tracks. In the classical (conventional) design of railway tracks, the ballast is often considered as a flexible medium to simplify behavioural simulations during track analysis; as such, its continuous deterioration and accompanying plastic deformation are often disregarded.
