We talk about the Seikan Tunnel in Japan, which is the deepest and longest underwater train tunnel in the world. It connects the islands of Honshu and Hokkaido, and was built through solid rock and under high water pressure, taking 17 years to complete. The tunnel is designed to resist earthquakes, flooding, and even typhoons, and trains can travel through it at speeds of up to 320 kilometers per hour. | Auto Viral
