Strength through Innovation

At our modern production sites, we produce products for innovative track systems, such as ecologically sensitive green track systems, 3-track sleepers and the ZSX Twin Sleeper. We have expanded our product portfolio to include longitudinal sleepers - we are still the sole manufacturer in this field. We have a production capacity of over a million reinforced concrete sleepers per year. Our quality assurance system corresponds to DIN ISO 9001.

Sleepers

Introduction

There are two basic sleeper types: transverse and longitudinal sleepers

  • Transverse sleepers are precast concrete parts laid at an angle to the centre of the track.
  • Longitudinal sleepers are precast concrete parts laid vertical to the centre of the track.
Sleeper surfaces are marked with the following designations:

  • Leonhard Moll manufacturer's mark
    - LMB Biebesheim factory
    - LML Laußig factory
    - LMH Hannover factory
  • Year of manufacture (e.g. 06)
  • Rail foot width in mm (e.g. 150 mm for UIC 60)
  • Classification mark (e.g. B 70-N)
  • Date stamp on the head of the sleeper
The sleepers are manufactured in accordance with the "technical delivery conditions for track and turnout sleepers in ballast Track or Slap Track Applications" DBS 918 143" (DBS: Deutsche Bahn Standard / previously BN Bahn Norm/ Railway Standard) along with the DIN EN 13230 standards series.
