The Gotthard Base Tunnel is one of the world’s most beautiful engineering marvels.
The daunting task of building the Gotthard Base Tunnel between Switzerland and Italy has been completed. However, trains will start using the tunnel only from June 2016.
The 60 km long tunnel will reduce travel time between Zurich and Milan by one hour making it a 2 hour and 50 minute journey.
The Gotthard Base Tunnel consists of two 57-kilometres-long single-track tubes, on which trains can travel at a maximum speed of 250 kilometres per hour.
With a route length of 57 km, it surpasses the Seikan Tunnel in Japan. Around 2,000 workers toiled over 20 years to build this tunnel. Eight workers lost their lives during the construction.
The Gotthard Base Tunnel is also the world's deepest railway tunnel ever constructed.
A straight route with no curves or level crossings on the overground sections, the Gotthard and Ceneri Base Tunnels together make the project one of the world's most outstanding engineering projects.
AlpTransit Gotthard AG, a wholly owned subsidiary of the Swiss Federal Railways built the tunnel at a cost of $10.3 billion.
