This latest generation wooden sleeper combines the current insights from research and development with the ecological aspect of renewable/sustainable raw materials. The SystemSleeper combines the principles of the wooden sleeper which has been used for centuries and combines these with innovative aspects:

• a mechanical pre-treatment by slit perforation (incising) which is new in Europe
• use of alternative oily wood preservatives
• impregnation processes specific to wood species
  a. single impregnation for Oak
  b. double impregnation for Beech and Pine

It is a high-quality alternative to the creosote treated sleepers and is intended to ensure the use of wooden sleepers in the track superstructure even beyond a ban of creosote.

The system has been registered with the European Patent Office (EPA 17169384.9). This ensures that all sold FSS are of consistently high quality.

FSS Fürstenberg-System-Sleeper^® AT A GLANCE:

Mechanical pre-treatment:

• accelerated and more homogeneous drying
• reduces drying cracks
• increases penetration
• optimizes the retention for long-term protection

Alternative oily wood preservatives:

• alternative oils as the basis for wood preservatives
• hydrophobic, thus long-term elasticity of the wooden sleeper
• free from tar oils and their components
• all active ingredients meet the requirements of the European biocidal legislation
• low odour
