Kershaw® RH446 Rail Heater

 

 

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® RH446 Rail Heater is designed to heat the rail in order to expand it prior to installation. When the rail cools and contracts, the rail will be under tension. This will help reduce rail deformation during seasonal climate changes throughout the year. The Rail Heater consists of a prime mover (Power Car) and a burner car. 

 

 

 

Description: The Rail Heater is designed to heat the rail in order to expand it prior to installation. When the rail cools and contracts, the rail will be under tension. This will help reduce rail deformation during seasonal climate changes throughout the year. The Rail Heater consists of a prime mover (Power Car) and a burner car. The overall length is 76 ft. 6 1/2 in. The Overall width is 8 ft. 2 3/8 in. The height of the rail heater from the ground to the top of the cab is 11 ft. 5 7/8 in. and is designed to conform to AAR Plate C when transported on 48 in tall equipment car.
