Gotthard tunnel: The world’s longest and deepest railway tunnel officially opens

1 June 2016  •  Author: Katie Sadler, Digital Content Producer, European Railway Review

Switzerland’s Gotthard Base Tunnel, the world’s longest and deepest railway tunnel, officially opened on the 01 June 2016, 17 years after the start of construction.

Gotthard Base Tunnel

Switzerland is celebrating the opening of the 57 kilometre Gotthard Base Tunnel which will connect northern and southern Europe under the Swiss Alps.

With 26 million tonnes of freight transported through the Swiss Alps by rail every year and 80 percent of this being transit traffic, Switzerland is said to be at the heart of one of Europe’s most important freight transport axes.

The £8.2bn Gotthard Base Tunnel is integral part of expected growth and will help provide an alternative to road transport for both freight and passengers.


Construction of the Gotthard Base Tunnel

During the construction of the Gotthard Base Tunnel, construction workers had to bore through a wide variety of different rock strata, from hard granite to crumbly sedimentary rock.

Tunnel boring machines carried out 80 percent of the work in the main tunnels and conventional blasting methods were used for the remaining 20 percent. A total of 28.2 million tonnes of excavated material was removed from the tunnel.

In order to save time and money, engineers worked on different sections of the tunnel at the same time. Workers, materials and machinery were transported to construction sites in the mountain via access galleries and shafts. With rock cover up to 2,300 metres in depth, temperatures inside the mountain reached as high as 50 degrees Celsius.

    Regarding the graphic of the freight train, this tunnel seems even not to be in Switzerland.
    Hopefully other data or more honest.
    To make it really good is as cheap as to make it bad, and disbelief will not arise.

  2. According to the picture it should be called the Matterhorn Basis Tunnel…
