World’s longest and deepest rail tunnel in Switzerland

Switzerland says it will revolutionise European freight transport.

The 57km (35-mile) twin-bore Gotthard tunnel will provide a high-speed rail link under the Swiss Alps between northern and southern Europe.

The tunnel will overtake Japan’s 53.9 km Seikan rail tunnel as the longest in the world and push the 50.5 km Channel Tunnel linking the UK and France into third place.

Goods currently carried on the route by a million Lorries a year will go by train instead.

The world’s longest and deepest rail tunnel is to be officially opened in Switzerland, after almost two decades of construction work.

German Chancellor Angela Merkel, French President Francois Hollande and Italy’s Prime Minister Matteo Renzi are due to attend the grand opening.
