      why tubes close each other so much? Normal speaking there must be at least two diameter distance between two tubes. For example if diameter of each tube is 12 meters, they must be 24 meters away from each other. Otherwise TBMs distort the working of each other. No?

        @Heiko I wondered the same. It might not be too hard, yet the tubes are too close to each other. Just guessing.

            Hi Lutz. You are confusing CityRailLink with the CentralInterceptor project. The former is 12 meter transport tunnel whereas the latter is a 5.45m waste water tunnel. In any case, knowing your preferences, you will be glad to hear that it is 2-0 for Herrenknecht.
