The tunnel runs for 57 kilometres under the Gotthard massif in the Swiss Alps region, and will be used as a key link between Northern and South-eastern Europe.

As well as relieving congested traffic movements, especially with the large number of  trucks carrying cargo at this time, it is expected the better flow will reduce air pollution.

A high speed rail service is to start using the tunnel from  2017, shifting heavy freight – and those trains will require less locomotive power than those running  through alpine country above ground..

Construction using huge drilling machines has taken  14 years; the project was first mooted in the 1940s.

It was a precision job, cutting through rock, the diretection-finding for the final link-up operating at a tolerance for error of 20 cm.

Crowds of workers, dignitaries and journalists, waiting in the tunnel space, applauded and cheered  as the link broke through.

For length underground, the Gotthard Base Tunnel displaces the Seikam Tunnel in Japan.
