The 33km Alpine Megatunnel Austria’s $6B Koralm Railway

Austria's Koralm Tunnel is one of Europe's most ambitious railway engineering projects. Stretching 33 kilometers beneath the Alps, this nearly €6 billion project took 18 years to complete and transformed travel between Graz and Klagenfurt from nearly three hours to just 41 minutes. In this video, we explore the incredible engineering behind the Koralm Tunnel, from massive tunnel boring machines and dangerous geological fault zones to groundwater challenges, underground safety systems, and advanced railway technology. Discover how engineers overcame extreme conditions to build one of the world's longest railway tunnels and strengthen Europe's Baltic-Adriatic transport corridor. ✨ 𝐉𝐨𝐢𝐧 𝐆𝐢𝐠𝐚 𝐁𝐮𝐢𝐥𝐝𝐬✨ https://www.youtube.com/@UCkWQEhTxV2lg_YM31qnk-IQ 🍁 𝐀𝐛𝐨𝐮𝐭 𝐆𝐢𝐠𝐚 𝐁𝐮𝐢𝐥𝐝𝐬🍁 Welcome to Giga Builds, where we explore the world’s most incredible construction projects, mega structures, and engineering achievements.
