High speed rail infrastructure is expanding globally, with existing networks being expanded and new ones created, as high speed rail is increasingly seen as a sustainable alternative to short haul flights.

High speed trains typically have stiffer bogies to give stability at high speed, but these can be damaging in curves, which invariably cannot be avoided as the high-speed railway approaches the centers of the urban destinations.

Friction Management at the wheel-rail interface has been robustly proven to be a sustainable, cost-effective strategy for mitigating problematic wear, noise, and corrugation phenomena by favorably manipulating energy and forces at this interface.

Our mission is to work with you to understand the advantages of friction management and identify how it can help you achieve your key goals:

  • Reduce annual program costs, including:

  • Rail grinding and rail replacement

  • Wheel truing and wheel replacement

  • Track component failure

  • Fuel consumption

  • Friction management materials

  • Maximize program benefits, including:

  • Control squeal and flanging noise

  • Avoid wheel climb derailments

  • Improve ride quality

  • Reduce track access requirements

  • Validate program performance 

How it works

Managing friction at the wheel-rail interface involves the establishment of optimal friction levels and controlling the relationship between creepage and friction forces. Different levels of friction are desired at the top-of-rail / wheel-tread interface and the rail-gauge / wheel-flange interface, and thus these two separate interfaces require different materials.

Friction Management for high speed rail systems can be achieved using both train-mounted and track-bound approaches and L.B. Foster have specifically designed solutions which are optimised for high speed rail. These solutions include our compact, slim line cabinets which are suited to tunnel and viaduct installations.

Train-mounted systems include both onboard solid stick and mobile liquid spray-based approaches.

  • Solid Sticks are formulated specifically for wheel flange or wheel tread application, each requiring different friction characteristics.

  • Mobile Spray systems apply desired quantities of friction control media at specific in-track locations.

Trackside systems make use of wheel sensing technology to detect passing traffic and apply friction control agents using rail-mounted applicator bars.

L.B. Foster has developed specialized technical packages to address these specific needs:

  • Trackside Gauge Face Rail Lubrication Systems

  • Trackside Top-of-Rail Friction Modifier Systems

  • Trackside Top-of-Rail Traction Gel Application Systems

  • On-Board Solid Stick Flange Lubrication Systems

  • On-Board Solid Strick Tread Friction Modifier Systems

  • On-Board Liquid Spray Application Systems
