Top-Of-Rail Friction Management Systems

KELTRACK® Trackside Family of Friction Modifiers

KELTRACK®  trackside products are water based liquid friction modifiers applied using L.B. Foster Rail Technologies’ PROTECTOR® Top-Of-Rail application systems.

When applied, KELTRACK® is transferred to rail vehicles from the top of rail and establishes dry thin film friction control at the wheel tread/top of rail interface. There are two KELTRACK® trackside solutions for transit and freight applications enabling KELTRACK® to provide a targeted solution for specific problems in these working environments.

KELTRACK® trackside transit solution is intended for use in targeted curve locations in transit systems.

KELTRACK® trackside solution assists freight and transit operators to deal with a wide range of problems from high rail wear to high lateral forces, energy consumption and rolling contact fatigue (RCF) development.

In its liquid form (prior to application), KELTRACK® is similar in appearance and certain characteristics to a water based latex paint. When applied to the top of the rail through PROTECTOR® top of rail distribution bars, the liquid material is picked up by the train wheels and carried down the track. The water component dries rapidly, forming a dry thin film.

The frictional characteristics of a KELTRACK® trackside transit or freight film provide:

  1. A controlled intermediate friction level that reduces curving forces, flange noise, wear, energy consumption and corrugations without affect braking or traction.
  2. Positive friction characteristics that dramatically reduce wheel squeal and short pitch corrugations.

L.B. Foster Rail Technologies PROTECTOR® Top of Rail Application System

The L.B. Foster Rail Technologies PROTECTOR®  is a trackside top of rail application system that is designed to apply KELTRACK® trackside products to the top of rail. The PROTECTOR® consists of a product reservoir tank/control unit, top of rail distribution bars and associated connecting tubes.

KELTRACK® is poured into the product reservoir and the control unit is programmed to pump KELTRACK® to the top of rail at specified intervals. These intervals are customisable. When KELTRACK® is pumped by the control unit it goes through the connection tubes and onto the Top-Of-Rail via the distribution bars which are attached to the side of the rail. The PROTECTOR® comes with an intelligent sensor that is attached to the rail and detects oncoming vehicles.

L.B. Foster Rail Technologies PROTECTOR® systems using KELTRACK® are designed to be placed prior to a curve (targeted curve application) where issues such as noise, lateral forces and corrugated rail are a concern. By addressing these concerns customers can significantly reduce noise complaints as well as defer costly rail replacement and rail grinding.
