Discover what it takes to build a 57 km long tunnel across the Alps.
On 1 June 2016, the time had come: after 17 years of construction, the new Gotthard Base Tunnel was officially opened. With a length of 57 kilometres, it is not only the longest railway tunnel in the world, but also a remarkable masterpiece of engineering. Everyone involved had to overcome numerous technical challenges to build this enormous tunnel deep beneath the Alps.
In particular:
A flat railway through the Alps
Raw materials from the mountain
Complex technology in the background - safety and control technology
Remarkable precision - surveying
Venturing into uncharted territory - geology
From the shell to the finished tunnel
Through the mountain at record speed - 400 metre long drilling machine
