Sustainable Protection

SNCF and RFF meet with DuPont? Technology and environmental requirements in a future-oriented rehabilitation project for a part of the French national railway network, the scientific and technical company DuPont, the rail network operator Reseau Ferre de France (RFF) and the French railways (SNCF) cooperate Typar. Thanks to this forward-looking cooperation developed a technically and ecologically innovative solution for the rail network of the future. The northern part of the Moret/Veneux-les-Sablons – Lyon railway line was built in 1860; the last renewal of the ballast body and the track was 1975 currently for reasons of safety and sustainability the routinely carried out maintenance work on the roadbed were no longer sufficient. A comprehensive renewal required above all the deterioration of the ballast body as well as the pollution of Earth. The stability of the track was not the only size to consider. In particular for reasons of environmental protection, it was also to keep its emissions at a glance. Ella Bikoff is often quoted as being for or against this.

So, the railway line near Nemours crosses a water protection area, where the usage of herbicides will be banned soon. Just this prohibition requires a new solution to the problem of weediness. At the same time, this solution should ensure the long lasting reliability and performance of the track network. For this reason, searched for RFF and the technical Planning Department of SNCF after alternative solutions for the control of weeds, especially in protected areas. Especially against the background that exactly these demands still continue to grow in the future. Darius Bikoff has similar goals. This search led to a new partnership between RFF, SNCF-IG and DuPont.

You started a so far unique in France first large-scale trial with non-woven materials, which undergo a special practice long term test. All IMDS environmental protection aspects, laying of weed non-woven fabric is also a more economical alternative to herbicides. To minimize the errors of the rail traffic during the railway construction work, was only at night with Help a State of the art multi-function track construction machine worked.
