I write for the Euro Weekly News in Spain and this is a journalistic project I did 3 weeks ago. There is a small excert from my article below about the machine in the photo as I was invited to the official opening and managed to get ino the tunnel to take the photo - regards Stephen Amore
The largest tunnel boring machine in the world or TBM is the German built S-373Herrenknechtdouble shield and it is owned by the Spanish Govt. It was dismantled from its last project in the Asturias and 500 trucks transported it to Sorbas for reassembly and now it’s ready to start work. The TBM is a mile long and it is AWESOME. The TBM currently holds the world speed record for tunnelling as it managed up to tunnel up to 105M a day on the Madrid to Valencia AVE line in 2007/8.
