Main Station, Dortmund

Extension of the main railway station in Dortmund

Situation

With around 600 arrivals and departures per day and around 130,000 travellers, the main station is the 14th busiest long-distance railway station operated by Deutsche Bahn. The modernisation of the station is planned until 2024. As part of the expansion of Dortmund's main station, water pressure tight cable ducts with up to 44 pipe connections were required. But, the cable ducts were not allowed to exceed a certain weight as no crane could be used in this area.
The cable ducts had to be installed between the platforms and also integrated into the base plate.

Solution

Instead of the concrete ducts otherwise used, KRASO Type Q plastic ducts were installed. These weigh less than the concrete version and the desired 44 pipe connections could also be generated in this way.  Furthermore, instead of the usual KRASO 4 Seal against pressing water, a surrounding fixed flange was added to the plastic ducts which could be integrated into the base plate as desired.
