Inside the World’s Longest Undersea Railway 🚆 How Denmark Built the $7B Fehmarn Tunnel

Описание: A train tunnel longer than the English Channel—built under the sea?
Step inside the world’s longest undersea railway and discover how Denmark is constructing the $7 billion Fehmarnbelt Tunnel, one of the most ambitious engineering projects ever attempted.

In this video, we take you inside the Fehmarn Tunnel, a record-breaking immersed undersea railway and road tunnel linking Denmark and Germany. From massive concrete tunnel segments to cutting-edge construction techniques, you’ll see how engineers are building an “impossible” tunnel beneath the Baltic Sea—and why it’s changing the future of European transport.
Watch till the end to see how thousands of workers, giant tunnel elements, and precision engineering come together beneath the sea.
