The whole excavation, from Linate to San Cristoforo, about 15km in each direction (including the sections of the stations and artifacts), was in fact completed. The two TBMs (Tunnel Boring Machines), dedicated to the construction of the odd and even tunnel of the Centro section, started in March 2019 from the Tricolore station, thus completed their journey in the city center, excavating and laying over 6,000 prefabricated rings that make up the 9 km of the tunnels of the central section.
