Case study: High Output Ballast Cleaning System – Reducing Ballast Waste on Britain’s Rail Network
Ballast is the graded stone sub-base that forms the track bed upon which railway sleepers are laid. Its function is to support the track and aid drainage. After twenty years on the infrastructure, ballast needs to be renewed. The track itself is designed to last for forty years, but it is Network Rail’s High Output team’s responsibility to regularly clean the ballast without replacing the whole track.
