The 50-kilometre underwater feat that shrunk the distance between nations
In short: Explore how a massive engineering project turned centuries of dreams into a reality, connecting London and Paris in just over two hours. This documentary reveals the technical hurdles of operating an international rail line beneath the sea.
Launched in 1994, Eurostar utilizes the Channel Tunnel—the world's longest underwater structure—to transport approximately 10 million passengers annually. The tunnel sits 75 metres below the surface and required six years of construction to complete. Operating this network involves navigating strict power, temperature, and safety constraints unique to underwater travel. Furthermore, the train must comply with multiple national rail regulations while managing border zones within historic stations across the UK, France, Belgium, the Netherlands, and Germany.
