Progress Rail’s Maintenance-of-Way (MOW) division was born out of the movement toward mechanization in the railroad industry and introduced the first Kershaw® Ballast Regulator in 1945. Today, Progress Rail supplies Kershaw® MOW equipment, providing machines to all Class I railroads, transit and short lines and contractors around the world.
The Kershaw® 44-2 Rotary Scarifier is a self-propelled machine designed to remove ballast, wood chips, and other debris from the cribs where old ties have been removed.
