Gauge Face

Friction Management Applicator

Gauge Face Friction impacts rail/wheel wear, rolling contact fatigue development, fuel efficiency, flange noise and derailment potential. An effective lubrication system like LB Foster's Wayside PROTECTOR IV® delivers precise, controllable, and reliable application of gauge face grease to ensure you get the most out of your rail system.

Gauge Face friction can have a significant impact on your rail network. An effective lubrication system like LB Foster’s Wayside PROTECTOR IV® delivers precise, controllable, and reliable application of gauge face grease that eliminate a variety of friction-related issues.

Gauge Face Friction impacts:

  • Rail/wheel wear
  • Rolling contact fatigue development
  • Fuel efficiency
  • Flange noise and
  • Derailment potential

Wayside Protector IV®
Track Lubrication System

The Protector IV® is a field proven electrical trackside lubricator that provides the most precise application of rail curve grease with minimal maintenance. The system includes:

  • A choice of tank capacities (90kg or 360kg)
  • Easy to operate solid state digital controls
  • Remote Performance Monitoring
  • L.B. Foster’s patent-pending foam technology
  • Non contact, ‘smart’ magnetic wheel detector
  • Is available in AC power (110v or 220v) or DC Solar (12volt)
  • The 360kg tank is available as a dual unit and can service 2 tracks from the same location

GreaseGuide Applicator
GreaseGuide Technology

The Protector IV® uses LB Foster’s patented GreaseGuide technology to accurately deliver lubricant where it needs to go. Grease is applied to the passing wheels using industry-leading GreaseGuide application bars that provide consistent controlled film to increase carry-down and reduce wastage.

Friction Management Lubricant

We supply high-performance grease designed with innovative oils to provide efficient lubrication and protection under a comprehensive set of performance requirements.

Grease provides the lowest friction level on the gauge face of the rail at the furthest distance. Using premium grade grease allows you to space applicators further apart resulting in lower capital and maintenance costs.

We supply a number of friction management lubricants.

Wayside Protector IV®
Track Lubrication System

L.B. Foster’s PROTECTOR series trackside systems are the industry standard. The PROTECTOR is designed to apply either gauge face grease or revolutionary friction modifiers to the top of rail. This innovative system is easy to install and consistently delivers precise, controllable, and reliable application.

Protector IV® Benefits

  • Field proven through continuous development over 10 years by the world leader in Total Friction Management
  • An efficient compact design that allows easier placement in the field but still retains the benefits of good reservoir size and a clean hands compartment for access to the control systems.
  • Designed for a simple, fast installation and an easily accessible maintenance regime the Protector is an ideal field installation solution.
  • Electronic controls – the grease output is accurately controlled giving optimum and consistent delivery across a wide temperature range thus running costs minimized as grease usage is optimised
  • Only four Grease Distribution Units (GDU’s) are required resulting in reduced maintenance burden plus quicker installation and commissioning times.
  • All of the major components used within the lubricator are custom designed for the railway environment
  • More than 50000 supplied worldwide and proven to flexible in a wide variety of applications and conditions.
  • The grease and controls compartments are separate and with secure locking
  • Ease of filling through a top position open access with a comfortable filling height.
  • Small footprint and narrow orientation ensures driver’s line of site is not obscured.

We are the exclusive agents for LB Foster’s Total Friction Management solutions, which includes a wide range of proprietary systems to control friction between the wheel and rail for transit and freight rail applications.

For more than a century L.B. Foster has provided the materials necessary to build and maintain the world’s infrastructure and their friction management products and delivery systems provide substantial cost benefits by maximising equipment performance and minimising wear at the wheel/rail interface.

Friction Management Benefits on Transit Systems

Uncontrolled friction at the wheel/rail interface on a transit system results in and contributes to a number of detriments including: curve noise, excessive wheel and rail wear, corrugations and rolling contact fatigue, wheel flats, SPADS (signal passed at danger due to lubricant on the rail head), higher fuel/energy consumption and potential safety issues like wheel climb derailment and high lateral focus.

A Friction Management system will extend the life of your rail asset whilst ensuring increased safety and efficiency and reduced noise.
