Gotthard tunnel: World's longest and deepest rail tunnel opens in Switzerland




The world's longest and deepest rail tunnel has officially opened in Switzerland, after almost two decades of construction work.
The 57km (35-mile) twin-bore Gotthard base tunnel will provide a high-speed rail link under the Swiss Alps between northern and southern Europe.
Switzerland says it will revolutionise European freight transport.
Goods currently carried on the route by a million lorries a year will go by train instead.
The tunnel has overtaken Japan's 53.9km Seikan rail tunnel as the longest in the world and pushed the 50.5km Channel Tunnel linking the UK and France into third place.
A live relay carried a speech from the southern end of the tunnel, in Bodio, by the Swiss federal transport minister, Doris Leuthard.
Afterwards two trains set off in opposite directions through the tunnel, each carrying hundreds of guests who had won tickets in a draw, and the new route was formally open.
A lavish show then got under way for the assembled guests in Erstfeld, with dancers, acrobats, singers and musicians celebrating Alpine culture and history.
