Below the protected monument, the „Kaufhof“ building at Kö in the heart of Dusseldorf, a tunnel with a connecting platform to the existing railway station „Heinrich-Heine-Allee” is built, which is exactly situated in the middle of the new “Wehrhahn” line.
During the construction of the Vienna underground line 2 extensive dewatering works with approx. 270 wells and approx. six million pumping hours were required. An electronic monitoring and control system made the measure safe.
6 km railway tunnel from Stuttgart central railway station to Bad Cannstatt as part of the large-scale project „Stuttgart 21“.
