Ballast Regulators

A ballast regulator ploughs and sweeps ballast after installation to tidy the track and facilitate tamping. It can also be used to reprofile the shoulder of the track. The Plasser and Theurer USP 5000 can store excess ballast and drop it in areas where ballast is depleted or remove it from the worksite. It is self propelled and can travel at speeds of up to 72 km per hour to and from the worksite.
