How Japan is Building a $72B Train that Flies Through a Mountain

How do you build a $72 billion train that flies at 603 km/h without ever touching the ground? Welcome to NEXTGEN MANUFACTURING. In this documentary, we go inside the extreme engineering of Japan’s Chuo Shinkansen Maglev the most expensive and technologically advanced railway megaproject in human history. To connect Tokyo and Nagoya in just 40 minutes, engineers are utilizing superconducting magnets cooled by liquid helium to literally levitate the train. In this technical deep-dive, we analyze: Superconducting Physics: How liquid helium and figure-8 coils create frictionless levitation. The Alpine Build: Executing the world's deepest railway tunnel 1,400 meters below solid rock. The Cost Explosion: Why boring through 300-million-year-old geology drove the budget to $72B. The China Rivalry: The high-stakes global race for 600 km/h commercial supremacy. Subscribe to NEXTGEN MANUFACTURING to understand the incredible machines, blueprints, and megaprojects that built our world. #MaglevTrain #Megaprojects #HowItsMade #Japan #FactoryTour #Engineering #Maglev #Documentary #BulletTrain #Construction #InsideTheFactory #Tunnel #FullProcess #Aviation #Trending ⚠️ IMPORTANT: ABOUT THIS VIDEO ------------------------------------------------------------------- This is an educational documentary analyzing the engineering and construction of public infrastructure, based entirely on open-source information.
