Swiss dig world’s longest tunnel
As long ago as 1994, the Swiss voted in a nationwide referendum to put all freight crossing their country onto the railways. Naturally, such an ambitious plan was not going to happen overnight, but now the project dubbed the engineering feat of the 21st Century is slowly taking shape.Deep beneath the Alps, the Swiss are building a high-speed rail link between Zurich and Milan. It will include, at 57 kilometres (35 miles), the world’s longest tunnel.
