Sleepers types on main tracks

Kilometres of main tracks by type of sleepers since 2006.

In general, the rails are fixed on a support (sleepers, longitudinal beams, wood pieces) and, exceptionally, on a solid concrete slab.

The sleepers have a double purpose:

  • to keep the two rails in place and thus achieve and maintain the track gauge imposed;
  • to support the rails and transfer the loads of the trains evenly to the ballast.

On the main tracks, you will find the following type of sleepers :

  • Wood : in oak or azobe
  • Concrete : two generation, old and new
  • Metal
