The RGS grinder platform is a natural supplement to any production rail grinding program, allowing a Railroad to grind trouble areas on open rail as it travels between switches, crossings, and other specialty track work. The RGS Grinder has 24 stones driven by 30 HP electric motors, allowing it to grind a switch or crossing in fewer passes than any other specialty grinder in the world. It can grind a complete switch in just six minutes, and achieve speeds up to 12 mph during open rail grinding.
