In 2006 the KLP® Hybrid Polymer Railway Sleeper was introduced to the European railway market. This sleeper combines the damping derived from polymers with the elastic bending stiffness of steel. Not only is it a replacement for timber sleepers, but it has an expected design life of 50 years, outlasting timber by a factor of 2-5 times. Early in 2017, the German Federal Railway Authority (EBA) granted type approval for operational testing of various types of KLP® Hybrid Polymer Sleepers, all of which have been specially developed for their unique applications.
Hybrid polymer sleepers for light rail, tunnels, viaducts, bridges, passenger and goods transport
KLP® Hybrid Polymer Sleepers (with steel reinforcement) offer a combination of the required stiffness, excellent vibration cushioning and sound dampening (typical noise reduction of 3-5 dB on bridges). High durability and strength are achieved due to the ductility of hybrid polymer in combination with the strength of steel. Further advantages include low life cycle costs and weight reduction and when dealing with low ballast depth, the high dampening characteristics of the hybrid polymer sleeper compensate for the decreased elasticity of the ballast. By this you can achieve a desirable continuous track stiffness. The city of Amsterdam acknowledged these benefits when they approved the use the KLP® Hybrid Polymer Sleepers in 2015 to replace parts of their light rail infrastructure.
Industry & life cycle cost reduction in track
KLP® Hybrid Polymer Sleepers are a sustainable alternative to concrete and timber sleepers. These polymer sleepers have high chemical resistance to moisture, acids and salts, compensate for the reduction in elasticity of the ballast due to ballast contamination, do not break in the event of derailment and have high lateral resistance, making them ideal for sharp turns. In addition, the KLP® Hybrid Polymer Sleeper ensures a much lower maintenance frequency. They have already proven themselves in track through multiple installations across Europe. A few examples are for Corus-Tata Steel in the Netherlands, Voestalpine Steelworks in Austria and Vattenfall Mining in Germany.
Australian representative Link Asia Pacific
In 2015 Lankhorst appointed Link Asia Pacific as their sole agent for Australia and New Zealand. Several industry experts and track owners showed their interest at the joint stand (Lankhorst Engineered Products and Link Asia Pacific) at the recent AusRail2017 conference and exhibition in Brisbane.

Link Asia Pacific
Link Asia Pacific (LinkAP) represents Lankhorst Engineered Products BV for the Australian Railway Market. In partnership, we offer commercially and technically robust hybrid polymer sleeper solutions to track owners and operators.
Specific applications for KLP® (“genuine Lankhorst products”) composite sleepers are:
- On bridges, where concrete is deemed too brittle and too heavy, reduction of noise
- On turnouts, especially non-standard types, as concrete has to be prefabricated and timber does not last that long
- On main track, where there is inferior ballast bed (concrete sleepers need considerable more ballast thickness than timber or composite)
- On main track where maintenance is carried out by replacing timber sleepers
