Thanks David, it's nice to see further progress. Amazing to think that it will take six years to fit out the tunnel from 2010-2016. I like the pictures taken in the space between the cutting face and the rockface when the engineers have to repair the cutting blades, but not a good place to be when they switch it back on and it crawls forward millimetre by millimetre...
It's amusing that although the Swiss are proud of it and are keen to visit the construction site on open days they're not actually building it themselves!
Construction is soon to start on the main tunnels of the Italy/Austria Brenner Base Tunnel (55 km, a bit shorter than the Gotthard) so it looks like the tunnel industry will be busy for many years to come!
