The day will come when man will have to fight noise as inexorably as cholera and the plague.
FFU synthetic wood
Railway sleeper Since 1980 over 2,300,000 synthetic wood sleepers fitted sustainably on 1,400 kilometres of railway track. Main areas of use are the highly stressed track sections such as switches and bridges.
FFU synthetic wood railway sleepers
Continuous glass fibres and polyurethane are combined to a high quality and long lasting material.
FFU has the life expectancy of high quality plastic and the weight of natural wood and can be worked like natural wood.
Fiber Reinforced Foamed Urethane = FFU
In 2008 and 2013 Munich Technical University conducted examinations of the material properties of FFU synthetic wood. The FFU synthetic wood sleepers tested had to partly meet the requirements imposed on concrete sleepers.
The FFU synthetic wood sleepers met all the set requirements.
The reports by Munich Technical University turned out extremely positive for FFU in all areas.
Based on these favourable results, the German Federal Railway Authority granted Approvals in 2009 and 2013 to operational trials for the safe use of railway sleepers of FFU synthetic wood on Germany's railway infrastructure.
FFU synthetic wood can be used on railway bridges technically and commercially just the same as conventional natural wood.
Installing FFU sleepers on railway bridges brings significant additional engineering design benefits in bridge construction and for the environment.
Operators, and their accountants, who are regularly faced with high costs and maintenance requirements for individual switches, appreciate the many benefits of FFU synthetic wood.
On top of this, FFU synthetic wood is dimensionally stable when manufactured in any length and thus offers many benefits when used in switches.
The German Federal Railway Authority (EBA) and the Swiss Federal Transportation Office granted approval in 2014 for the use of flat sleepers with a height of 12 cm on the respective railway networks.
Sleepers with a height of only 10 cm are favoured for use on urban infrastructure with low axle loads.
At its initial trial back in 1980, bi-block sleepers of FFU synthetic wood were installed on a ballastless track segment in a tunnel.
Other applications include level crossings and long bridge sleepers.
FFU synthetic wood has been installed on more than 1,400 km of track worldwide since 1980 (as of 2015).
Its forecast service life of 50 years is getting ever closer to being confirmed in practice.
Rail web noise shielding Noise reducing installations on over 80 km of German railway track since 2010. According to DB AG, maximum noise reduction also at high track decay rates.
Rail web noise shielding - wraps the rails with Calmmoon technology for the reduction of airborne noise energy and of vibration energy. Two clip fastenings secure the shielding on the rail permanently.
4 kg per linear metre of rail are quickly distributed by hand and installed safely. Track maintenance tasks such as ballast tamping and ballast sweeping on track systems that have been fitted with Calmmoon Rail can be carried out as usual without any restrictions.
There is a time for everything.
To achieve the possible, one must attempt the impossible again and again.
By three methods we may learn wisdom: first, by reflection, which is noblest; second, by imitation, which is easiest; and third by experience, which is the bitterest.
I have the simplest tastes. I am always satisfied with the best.
Quality is more important than quantity. One home run is much better than two doubles.
