A new project was approved in 1995 for a line running from Campo Volo on the west border of the city to Porta Nuova, the main railway station in Turin.

An additional two stations, including one in the Leumann Village neighbourhood and another in the Cascine Vica district of Rivoli, were allocated €148 million.

Part of the Southern track will be elevated to reduce building costs (starting from Piazza Cattaneo to Cimitero Sud).

The following June, public consultations were announced and the new alignment, with the list of 23 planned stations was published on the city's website.

[11] In December 2018, the preliminary project was submitted to the Ministry of Transportation for funding approval, with an objective to start the bidding process by 2021.

[12] In 2019, the Italian government committed €828 million in funding for Line 2's total projected €3 billion cost, with construction due to begin in 2021 for a 2028 opening.

[14] Campaign literature, published on the then candidate's website during the Turin municipal election, 2016, show Line 3 using tracks that formally served the Ferrovia Torino-Ceres railway.

Since the election, Deputy Mayor and Chief of Urban Planning Guido Montanari has expressed interest in readapting the Torino-Ceres line to be part of the city's Metro network.

The route will include the west part of the city: Torino Dora railway station, Juventus Stadium, Amedeo di Savoia Hospital, Maria Vittoria Hospital, San Donato district, Campidoglio, Parella, Cenisia, San Paolo, Mirafiori Nord and Caio Maio Square.
