Steinach am Brenner, an Alpine village in Tyrol, is the site of the Brenner Base Tunnel, the longest underground railway line in the world at 64 km. Project manager Sebastian Reimann emphasizes European collaboration, while colleague Andreas Ambrosi highlights the involvement of eleven nations and top European companies like Herrenknecht, which uses powerful tunnelling machines. Herrenknecht, founded by Martin Herrenknecht, faces competition from China and advocates for protective tariffs to support European industry.
