Friction Modification

Friction Modification (Rail Technologies)

Reducing friction on the running surface of the rail has been proven to reduce lateral forces, rail wear, fuel consumption, and Rolling Contact Fatigue (RCF).

At the Top of Rail (TOR), we look to introduce our Friction Modifier, called KELTRACK. Reducing friction on the running surface of the rail has been proven to reduce lateral forces, rail wear, fuel consumption, and Rolling Contact Fatigue (RCF). The key is to reduce the friction levels to an intermediate level so that there is no effect on the traction and braking of the train.

KELTRACK Friction Modifiers are specifically designed to manage friction levels on the top of-rail (TOR) at an intermediate and controlled level of 0.35. Containing no oils or greases, KELTRACK is similar to a latex paint and is designed to dry rapidly in the rail/wheel interface.

Top of Rail (TOR) Friction Impacts:

  • Lateral Forces
  • Rail / Wheel Wear (TOR, Tread)
  • Rolling Contact Fatigue Development
  • Fuel Efficiency
  • Squeal Noise
  • Flange Noise (indirect)
  • Corrugations
  • Hunting
  • Derailment Potential
  • (L/V, rail rollover)
