The 57 km Railway Tunnel That Transformed Europe Forever

Switzerland built one of the greatest engineering projects in modern history, the Gotthard Base Tunnel, a 57 km railway tunnel carved deep beneath the Alps. After 17 years of construction, engineers moved through extreme heat, complex geology, and millions of tons of rock to create the world’s longest railway tunnel. This documentary explores how massive tunnel boring machines, advanced engineering, and careful planning helped transform European transportation by creating a faster, flatter route through the mountains. Discover the challenges, technology, and human effort behind the tunnel that changed how Europe moves. 00:00 Switzerland’s Impossible Tunnel Under The Alps 00:17 The $12 Billion Engineering Challenge 00:25 The Longest Railway Tunnel On Earth 00:57 Why Europe Needed A Tunnel Through The Alps 01:11 The Problem With The Old Gotthard Route 01:35 The Dream Of A Base Tunnel 01:56 Why Alpine Geology Was A Major Challenge 02:20 Switzerland Approves The Mega Project 02:33 Construction Begins On The 57 KM Tunnel 03:04 Fighting Unknown Rock And Extreme Conditions 03:49 Working 2.3 KM Below The Surface 04:09 Heat, Water, And Underground Challenges 04:37 The Dangerous Rock Zones 05:10 The Giant Tunnel Boring Machines 05:56 Access Shafts And Construction Strategy 06:26 Thousands Of Workers Build The Tunnel 06:53 Drill And Blast Construction Method 07:23 Removing 28 Million Tons Of Rock 07:47 Building The Tunnel Lining 08:11 Breaking Through The Mountain 08:33 Installing Railway Systems And Safety Equipment 09:13 Testing The World’s Longest Tunnel 09:28 Opening Of The Gotthard Base Tunnel 09:37 How The Tunnel Changed European Transport 10:16 Moving Freight From Roads To Rail 10:57 Challenges After Opening 11:41 The Legacy Of A Mega Engineering Project 11:56 The Future Of Underground Engineering ✨ 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.
