Switzerland to open world's longest train tunnel

Switzerland to open world's longest train tunnel: "Switzerland is set to open the world's longest and deepest train tunnel - the Gotthard Base Tunnel - following the completion of its exhaustive safety and technical tests by The Swiss Federal Railways (SBB).

A 17-year pioneering project which extends for 57 km down to a maximum depth of 2300 m under the Gotthard massif, the Gotthard Base Tunnel will enter into service tomorrow (December 11).

The dual-track tunnel will bring northern and southern Switzerland closer together, and cut travel time between the neighbouring countries."
