Kershaw Skytrim 75 G2 Hi Rail

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 Hi Rail SkyTrim is a rough terrain, rubber tired vehicle with telescoping boom and saw-type cutter head designed to trim trees. Equipped with hydraulically controlled rail wheels, the machine can propel down the rail track in a matter of minutes.
