RFI - Turin-Lyon: legality protocol signed for the construction of the Italian section

On 18 October 2024, the Legality Protocol was signed between the Prefecture of Turin, Rete Ferroviaria Italiana (FS Group) and Calogero Mauceri, Extraordinary Commissioner for the national section of the adaptation of the historic Turin-Modane Bussoleno-Avigliana line.

 The Legality Protocol provides for collaboration between the Prefecture and RFI to monitor full compliance with the law in public contracts, developing, in addition to the standards required by law, additional forms of control, exchange of information and procedures that guarantee transparency. The provisions of the Protocol will concern the entire supply chain of companies entrusted with the construction of the Italian section of the Turin-Lyon line that will be involved in the construction of the works in any capacity. 

The adaptation of the Bussoleno-Avigliana section on the current historic Turin-Modane line includes interventions to strengthen the line, modernize technology, strengthen power systems, mitigate noise on the line, and widen the line to 750 m to allow the transit of freight trains. 

• The red Savoy TBM is at the Saint-Martin-la-Porte construction site

The first elements of the head of the red Savoy TBM began to arrive at the Saint-Martin-la-Porte construction site in September, on special convoys departing from the Herrenknecht factory in Germany: click here for the video. Meanwhile, underground, construction has begun on the overhead crane for assembling the TBM, which will then have to dig 9 km of tunnel to La Praz.

In parallel, the technical cavern of over 160 m has been completed on this construction site in correspondence with one of the two tubes of the base tunnel, where the advances in the mountain continue symmetrically with the traditional method towards Turin and towards Lyon.

At the height of the La Praz descent, excavation is being carried out on 5 fronts: the two traditional sections of the base tunnel, the logistics tunnel, the connection to the intertube tunnel and the area where the machinery for crushing the rock from the tunnel excavation will be installed.

 In Saint-Julien-Montdenis, the excavation with explosives on the two fronts of the entrance to the base tunnel has exceeded 1,000 m in both tunnels.

On the Avrieux construction site, the robot beton (special equipment that allows the placement of shotcrete along the surface of the shafts, with remote controls) has completed the first phase of filling one of the four shafts and is about to proceed on a second.

 In Italy, in Chiomonte, while the executive design of the 2nd phase of the construction site for the Italian section of the base tunnel continues, the construction of the new construction site junction on the A32 motorway is progressing outdoors with the construction of the piers for the two ramps and the start of the launching of the decks on the Turin side ramp of the junction.

Finally, at the construction site for the new San Didero truck stop, the construction of the piers for the overpasses of the ramps connecting to the A32 is being completed, as well as the systems inside the building that will house the command and control center.

In total, at the end of September 2024, 38.2 km of tunnels had been excavated, of which 14.4 km of base tunnel.
