Kershaw 46-2 Ballast Regulator


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.


Kershaw 46-2 Ballast Regulator has a one pass transfer plow, 36” (914 mm) wide reversible wings, and a broom attachment making it a powerful versatile machine for ballast shaping, shoulder profiling, and a variety of other track maintenance operations.
