On 21/12/21 the excavation activities for the new San Tomaso tunnel, a strategic part of the Terzo Valico dei Giovi – Genoa Junction One Project, and the first of the Genoa railway junction, were completed: click here to view. The breakthrough marks 83% completion of the underground excavation activities of the Junction project.  

The Genoa Junction project will strengthen regional and metropolitan connections, by quadrupling the Genoa Voltri-Sampierdarena line, and by building two new tracks (sixfold) between the railway hubs of Piazza Principe and Brignole.  The new San Tomaso single-track tunnel, approximately 1500-m-long, runs from the entrance to the Genova Brignole station up to the existing section of the San Tomaso Tunnel, where the underground level of Genoa Piazza Principe is located.  

The Genoa Junction project involves the building of two new tunnels, Colombo tunnel (1,409 m) and the Polcevera tunnel (2,167 m), whose construction will allow an increase in the capacity of the lines near the Genoa Junction, also potentially increasing the train frequency, by separating regional and metropolitan trains from long-distance and freight ones, and by connecting the last mile of the Terzo Valico dei Giovi to the Port of Prà -Voltri.
