The reason why: economical & eco-friendly compound sleeper alternative for track, switches & bridges

  • The objective: an ecological compound sleeper that combines the positive features of wooden and existing plastic sleepers​
  • Increased safety thanks to the incorporation of reinforcement (as with concrete sleepers)​
  • Initial market situation: planned creosote ban for wooden sleepers in Europe – unfortunately postponed for 2 years​
  • Further motivations for the development: “enabling green mobility”​
  • Confidence in own competencies & abilities: interaction during wheel-rail contact & Technology Centre in Werdohl for all test scenarios

Overview of product properties

Sustainability​

  • Scheduled creosote ban in Europe: environmentally friendly alternative to wooden sleepers without any use restriction​
  • Use of secondary raw materials in industrial quality​
  • 100% recyclable & resource-saving​
  • Preservation of the tree population​
  • Consistent material quality ​
  • High weather resistance (UV resistance, no moisture absorption) for applications in extreme, humid climate conditions​
  • Long service life

Operational safety​

  • Defined & consistent properties over the whole service life​
  • Low coefficient of thermal expansion​
  • High lateral track set stability & stable gauge:​
    • High anchoring pull-out forces​
    • Increased safety due to the use of reinforcement (as with concrete sleepers)​
    • High electrical resistance ​
    • High lateral sleeper resistance

LCC​

  • Good price-performance ratio for all-inclusive deployment & series production​
  • Significantly less maintenance effort & high durability > low life cycle costs

Excessive testing

Economical & eco-friendly sleeper alternative for track, switches & bridges

  • 150+ test characteristics were identified​
  • About 330 in-house trials were carried out to achieve the optimum material compound that satisfies the international standards ​and customer requirements​
  • Investigation of the impact of environmental temperatures on mechanical properties
  • Participation in the ISO and AREMA standardization committee for plastic sleepers: findings can be applied to the sleeper definition, and changes in the standards can be integrated in the product design at an early stage.
Multiple internal & external tests

Focus on various application fields

  • Wide range of application from urban transport to heavy haul already possible; focus for the future: safe deployment in tunnels​
  • No restrictions regarding design and moulding​
  • Mixing ratio and sleeper shape as well as the positioning and type of reinforcement can be adapted to application-specific specifications​
  • Combination with various rail fastening systems, also including W-systems​
    • Apart from the indirect fastening, the material and the production are excellently suited for direct fastening applications.

Wide range of customization options

For an accelerated / simplified installation process

  • Customers can choose between different rail fastening solutions – direct or indirect including safety guard:​
    • For W systems, the bead can be prefabricated for direct fastening.​
    • For switch designs: indirect fastening including guide rail and safety gear is also possible.​
  • Non-slip profiling with millimetre-precise embossing from two to five mm in height​
  • Tried and tested processing options: drilling, sawing, milling and grinding​
  • Prefabrication of the core holes for the sleeper screws: with and without tread, also inclined by 5°​
  • Adaptable sleeper geometry (length, height, width)

Long since in test operation – in various line environments
