The excavation work to build the world's longest railway tunnel beneath the Swiss Alps is complete.

The high-speed rail link in Switzerland, where passenger trains can travel at a maximum speed of up to 250 kilometres per hour, will be operational by 2016.

With a route length of 57 km, it surpasses the Seikan Tunnel in Japan.

A straight route with no curves or level crossings on the overground sections, the Gotthard and Ceneri Base Tunnels together make the project one of the world's most outstanding engineering marvels.
