Modern railway infrastructure often presents technical challenges for developers and builders alike, since high-speed railway tracks have to withstand enormous forces and vibrations. This also applies to the 123 km section between Erfurt and Leipzig/Halle, which forms part of the new Intercity Express (ICE) link between Munich and Berlin. Deutsche Bahn AG customers will eventually be travelling along this stretch at speeds of up to 300 km/h (190 mph), completing their journeys to or from the German capital in four rather than the current six hours. The ICE will travel over six major bridges and through three tunnels, the longest being the twin-tube Finne Tunnel with a length of almost seven kilometers. The precise control of the concrete paver that provided the bed for the subsequent track construction through the tunnel was accomplished with total stations and the 3D machine control system PaveSmart 3D from Leica Geosystems.
