Munich Technical University
In 2008 Munich Technical University carried out a technical examination of the FFU synthetic wood material. The FFU synthetic wood sleepers tested had to partly meet the requirements imposed on concrete sleepers.
FFU synthetic wood sleepers met all of the requirements imposed.
The report by Munich Technical University turned out extremely positive for FFU in all areas.
Based on these favourable results, the German Federal Railway Authority granted operational trials approval in 2009 for the safe use of FFU synthetic wood railway sleepers on the rail infrastructure of Germany.
Test of the world‘s thinnest synthetic composite sleeper
At 12 cm construction height, the world‘s thinnest ”synthetic composite sleeper“ (as of 2013) received positive test results in autumn 2013 for main line railways (22.5t) for speeds v < 200 km/h from the testing body for transportation route construction at the Technical University Munich.
Based on these favourable results, the German Federal Railway Authority and the Swiss Federal Transportation Office were able to grant operational trials approval in 2014 for the safe use of the 12 cm high FFU synthetic wood railway sleepers.
The Swiss approval also included tunnel installations where wooden sleepers are still installed prior to the replacement.
