The single-track section from Dieringhausen to Gummersbach will not only be given a new track but also a new deep drainage system. Here the railway wants to install the best on the market, namely PP Rail SN 16 pipes.
Dieringhausen is located in the Bergisches Land (meaning mountainous) region and, as the name suggests, it is not flat; rather, it is necessary to slice off at least Class 7 rock for deep drainage - a demanding task for the engineering team from Hering!
