Railway tunnel provides a modern connection of Zaventem airport close to Brussels to the European high-speed railway system and to E 19 motorway.
The 3.1 km long Oenzberg tunnel is part of the new Mattstetten-Rothrist railway line in Switzerland. This railway line improves the connection between Bern and Olten.
The North-South link Antwerp is part of the Brussels-Amsterdam high-speed line. The project comprises the reconstruction of the existing accesses, the construction of a passage under the main station as well as the construction of two tunnel sections from „Astridplatz“ to „Damplatz“.
