The most DEADLY Train Nobody Talks About

Building a 57-kilometer tunnel through the Alps took 17 years and cost over $12 billion, but the result is a massive engineering feat. This project required drilling from opposite sides of the mountain range to move 28 million tons of rock, an amount equivalent to five Great Pyramids. We examine the logistical reality of executing such a complex design under intense environmental stress, including the 2,300 meters of solid rock pressing down on the structure. It is a story of human persistence against extreme geological obstacles. Despite the dangerous conditions that claimed nine lives during construction, the team successfully connected the two sides of the mountain. We look at how they maintained stability against shifting terrain and why this tunnel stands as a testament to modern planning. This breakdown is for those interested in civil engineering and the infrastructure projects that shape our world.
