KLP® Hybrid Polymer
Track Sleeper

Designed for 50+ year longevity to reduce Total Cost of Ownership while maintaining continuous track stiffness. Made from recycled plastic with steel bars for superior strength and damping.

Maximize your track performance and sustainability

Optimize your railway infrastructure with our innovative polymer-steel composite sleepers designed for 50+ years of maintenance-free service.

  • Superior lateral and vertical stability
  • Low thermal expansion
  • 100% recycled & 100% recyclable

Next-generation track sleepers with optimized performance

Our latest KLP® Hybrid Polymer Track Sleepers from the 100 Series represent the next evolution in composite sleeper technology. Engineered with an innovative profiled design that allows full embedding in the ballast bed, these sleepers deliver superior lateral and vertical resistance compared to traditional rectangular designs while using 30% less material. Whether you operate freight lines, passenger railways, urban transit systems or industrial tracks across standard, narrow or broad gauge configurations, the 100 Series provides optimized track performance through advanced polymer-steel composite technology.

Traditional track sleepers

KLP® Hybrid Polymer Track Sleepers from our 200 Series offer all the benefits of composite technology in the traditional rectangular sleeper shape that track engineers know and trust. With the same 50+ year service life, 100% recycled content and maintenance-free performance as our entire range, these sleepers provide a familiar solution for standard track applications.

The 200 Series is also ideally suited for turnout and crossing applications where enhanced strength is required.

Why our KLP® Track Sleepers stand out

Ballast integrationFully embedded design maximizes lateral and vertical resistance for superior track stability.
Axle loadEngineered for axle loads up to 25 tons with consistent performance under demanding operations.
Third railCustomizable for electric rail systems requiring third rail conductor configurations.
Universal gaugeFor narrow, standard and broad rail gauges worldwide, from 1000mm to 1676mm track configurations.
Tunnel optimizedHeight-adjustable design down to 130mm profile for restricted clearance applications in tunnels.
Fire safety

Bfl-s1 fire and smoke classification (EN13501-1) ensuring strict railway safety compliance.
