The pre-assembly of turnouts or large turnout components, meaning the assembly of turnouts in the turnout plant instead of at the installation site, offers not only economic but above all qualitative advantages. The transport of such large turnouts (-parts) alone has not become established due to the limited distribution and availability of such means of transport. For this reason, RAILONE, in close cooperation with DB Netz AG, has developed a foldable turnout sleeper, which was awarded the CNA Innovation Prize in 2011.
The foldable turnout sleeper makes it possible to basically fold the areas of the turnout that are too wide for standard transport (L > 3 m) and to transport them in this state using standard flat cars.
