Gotthard Base Tunnel  

The Gotthard Base Tunnel is the world’s longest and deepest rail tunnel in the world with a length of 57 kilometers. It is located in Switzerland. There were two sections built inside the tunnel where trains can change to the other one way tunnel. The tunnel was not drilled from North to South nor the other way around.

It was constructed in five individual segments. A trip through the tunnel takes about 20 minutes. There are safety exits every few hundred meters. This tunnel was opened on June 1, 2016 and the full service began on December 11, 2016.

 

Quick Facts: –

  • The Gotthard Base Tunnel has 2 multifunction stations with water points for fire-fighting and rescue trains.
  • A total of 50 passenger trains travel through the tunnel each day.
  • The deepest point of the tunnel is 2.3 kilometers below Piz Vatgira. It is 1.5 times the depth of the Grand Canyon.
  • During the construction engineers had to dig and blast through 73 kinds of different rocks. A total of 28.2 million tons of rocks was excavated from the Alps.
  • The true length of all tunnels drilled is closer to 152 km including two tunnels, one for each direction, as well as access and safety tunnels.
  • The tunnel consists of two single-track tubes that are 40 meters apart and connected to each other every 325 meters by a cross-passage.
  • Although it is the world’s deepest tunnel it actually has no gradients. It is completely flat and straight.
