Ballast cleaner - Wikipedia

A ballast cleaner is a machine that specialises in cleaning the railway track ballast of impurities. Over time, ballast becomes worn, and loses its angularity, becoming rounded. This hinders the tessellation of pieces of ballast with one another, and thus reduces its effectiveness. Fine pieces of granite, like sand, are also.
