Ballast, like most things on the railroad, requires regular maintenance. Over time ballast begins settle and lose its shape. In addition, rock fragments from worn ballast, spilled commodities, locomotive sand (used for traction), and soil can prevent proper drainage. Railroads and contractors often use self-propelled equipment to maintain ballast.

October 6, 2017 – The traditional three-part recipe for a railroad – rock, creosote-soaked hardwood ties, and ribbons of steel rail – has remained essentially unchanged since the first iron horse was put to work. And just as ties and rails require maintenance and eventual replacement, the rock, known as ballast, also wears down, and out.
