Lyon – Torino TBM completed - Railway Gazette
Tunnelling is expected to get underway towards the end of this summer at Saint-Martin-la-Porte in France on the test bore for the base tunnel planned to carry a high speed line between Lyon and Torino. This will use a 12 m diameter TBM built by NFM Technologies at Le Creusot which was named ‘Federica’ on January 14.
Seems like they are going ahead with it.
