The world's longest and deepest rail tunnel is to be 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.
