The world’s longest and deepest rail tunnel has been opened in Switzerland. The 57 km (35-mile) twin-bore Gotthard Base Tunnel (GBT) will provide a high-speed rail link under the Swiss Alps between Northern and Southern Europe. The tunnel has overtaken Japan’s 53.9 km Seikan rail tunnel as the longest rail tunnel in the world. The full service will begin in December 2016. The tunnel has taken 17 years to build at a cost of 12.2 billion Swiss francs (£8.4 billion).
