The Albvorland tunnel is currently under construction in the expansion of the pan-European high-speed rail network. The building contractor, Deutsche Bahn Netz AG, places higher requirements on safety – also when it comes to the special sealing profiles between the lining segments.

Within the scope of the pan-European high-speed rail network expansion the approximately 60 km long new ICE railway line is being developed in the south-eastern portion of the metropolitan region of Stuttgart between Wendlingen and Ulm. From a transnational standpoint, it is a partial segment of the routing between Bratislava and Paris and is directly connected to the current large-scale project Stuttgart 21. In order to lead the ICE trains of Deutsche Bahn AG up here in the future from the new subterranean through station in the southern direction from the Stuttgart basin, extensive tunneling...
