Special sleepers

Our special sleepers provide a solution that meets any need, allowing us to offer a comprehensive solution to efficiently meet the needs of each client: 

Transition sleepers: special sleepers that allow for the transition between different types of track, overcoming different rigidities of slab track and ballasted track. Transition sleepers create the necessary elasticity steps and allow the track to be braced by means of one or two auxiliary rails.
