Transit Solutions


L.B. Foster has the most extensive and advanced portfolio of gauge face greases and application systems specifically designed for the transit environment.

Recognized globally as the experts in railroad friction management, we continue to develop innovative products that:

  • Extend wheel and rail life by reducing wear

  • Reduce flange noise

  • Reduce derailment potential

  • Reduce energy consumption

  • Reduce Rolling Contact Fatigue (RCF) development

Gauge face greases

Our gauge face grease portfolio starts with SYNCURVE® Transit, an exceedingly durable all-season rail curve lubricant giving the customer flexibility of either employing a lower application rate for existing spaced lubricators (up to 50% lower) or increasing lubricator spacing using current application rates. SYNCURVE Transit provides excellent protection in the wheel flange/gauge face interface and is ultimately biodegradable.

Along with SYNCURVE Transit, we also provide a full range of high-performance and environmentally friendly gauge face lubricants including:

  • PROCURVE® is a highly durable petroleum grease that can be used at lower application rates as compared to traditional rail curve lubricants. PROCURVE is specially formulated to meet the pumpability, adhesion and load carrying requirements of a premium rail curve grease. PROCURVE is available in summer, winter, and arctic grades.

  • BIOCURVE® LB2 is a premium quality readily biodegradable rail curve grease formulated with vegetable oils.  BIOCURVE LB2 has exceptional product stability and lower propensity for bar clogging compared to other biodegradable greases.  This product is recommended for locations requiring the highest level of biodegradability such as near waterways or other environmentally sensitive areas.  BIOCURVE LB2 is available in summer and winter grades. 

  • ECONOCURVE® is a grease specifically designed to provide good wear protection, weather resistance and effective carry down at an economical cost.  Both summer and winter formulations are available.

PROTECTOR® application systems

Built on over 40 years of in-service experience and continuous technological innovation, L.B. Foster PROTECTOR systems are known to be:

  • Exceedingly reliable

  • Easy to maintain

  • Consistent and precise in their application rate. Our innovative control system uses proprietary compensation algorithms to seamlessly adapt to changing operating conditions and consistently outputs the correct amount of grease.

Combined with our MC-4® application bars with GREASEGUIDES and our next generation Remote Performance Monitoring (RPM), the PROTECTOR system is the most advanced friction management system available in the world.

  • MC-4 applicator bars accurately deliver lubricant to wheel flange / rail gauge face. These two bars share our industry-leading channel and port design, providing equal and reliable delivery of grease to each port and preventing clogs.

  • L.B. Foster's patented GREASEGUIDE troughs re-direct and guide grease back to the wheel flange where it can carry out its intended purpose — protecting the rail and wheels. GREASEGUIDE technology helps to improve lubricant pick-up, thereby increasing carry-down and reducing waste.

ESA™ application systems

The ESA system features easily exchangeable, refillable lubricant cannisters which prevent ingress of dirt or air into the system and protect maintenance personnel from coming into contact with the lubricant. ESA can be used for either standard or grooved rail profiles and can be configured to apply through either drilled rail or standard applicator bars.

Whatever your gauge face lubrication challenge, we can help.
