World record on the Gotthard: The longest railway tunnel in the world has become a reality. On 15 October 2010 in the east tunnel, 30 km from the north portal and 27 km from the south portal, the final breakthrough of the Gotthard took place. At about 14:30, the tunnel boring machine, drilling from Faido, broke through the last metre of rock on the route to Sedrun.

The tunnel breakthrough was highly accurate. At 8 cm horizontally and 1 cm vertically, the deviation was very small...

Here is the video (the breakthrough is at around 1:50 in):

I may put together something over the weekend; but the First breakthrough on longest tunnel diary from 2006 already describes the tunnel.
