On Board Solutions

As part of the L.B. Foster Rail Technologies’ dynamic technology-driven approach to providing solutions suited to the customer’s needs, we offer a range of proprietary solutions to control friction between the wheel and the rail for transit and freight rail industries.

These solutions serve to reduce, increase or control friction at the wheel/rail interface in order to reduce costs and improve performance.

One such solution is our solid stick friction product range, which is simple to use, clean and environmentally safe.

Top of Rail Friction Modifier

L.B. Foster Rail Technologies’ Kelsan® HPF (High Positive Friction) Solid Stick Top of Rail Friction Modifier

The solid stick friction modifier is applied directly to the wheel treads of the rail vehicle and the HPF material provides a micron-thick ‘thin film’ layer between the wheel tread and the top of the rail. This provides a friction level of 0.35 (µ) on the wheel/rail interface of the rail system.

HPF On Board Sticks are applied using a spring loaded bracket/applicator assembly being specifically designed and built for each customer. The bracket/applicator assembly is attached to the bogie frame of the rail vehicle.

Benefits: Reduces TOR wheel squeal noise, short pitch corrugations and lateral forces.

Wheel Flange Lubrication

L.B. Foster Rail Technologies’ Kelsan® LCF (Low Coefficient of Friction) Solid Stick Gauge Wheel Flange Lubricant

The solid stick lubricant is applied directly to the wheel flange of a rail vehicle. The LCF material transfers to the wheel flange and in turn to the gauge face of the rail. A ‘thin film’ is left behind on the gauge face of the rail that provides superior lubrication to the wheel/rail interface throughout the railway system.

LCF On Board Sticks are applied via a vehicle mounted spring loaded bracket/applicator assembly being specifically designed and built for each customer. The bracket/applicator assembly is attached to the bogie frame of the rail vehicle.

The Kelsan® LCF On Board wheel flange lubrication system provides a 100% dry, environmental solution that avoids contamination of the track structure, ballast or vehicle equipment.

Benefits:

  • Extend rail gauge and wheel flange life
  • 100% dry system
  • Clean, environmentally friendly solution
