Line C is the future third line of the metro system of Rome, Italy. It will be the first fully automated line in the city. The line is currently under construction. The line reuses part of the old Rome-Pantano railway, a light railroad that is the last remaining part of the old Rome-Fiuggi railway.


From August 2006 onwards archeological investigations took place before construction could start. The first construction sites opened in March 2007, on Piazza Roberto Malatesta, to construct Malatesta station. Lodi station followed one month later.[1]

In May 2008 two Tunnel Boring Machines were set up at Giardinetti,[2] and two months later the old Rome-Pantano railway was truncated at Giardinetti to allow restructuring part of the old surface line, which will form part of the new metro. This stretch, from (Pantano-Centocelle) to piazza Lodi, will open in 2014.[3] The part of the line that crosses the city centre, from Venezia up to Clodio-Mazzini, is currently in its planning stages.

In 2009, during the excavations in Piazza Venezia (near the Capitoline Hill) remains of what has been identified as emperor Hadrian's Athenaeum were found.

Works on the different sections of Line C are supposed to be finished according to the following schedule:[4]

  • 2014: First section between Monte Compatri-Pantano and Lodi – currently under construction
  • 2015: Second section between Lodi and San Giovanni – currently under construction
  • 2020: Third section between San Giovanni and Colosseo - currently under construction


The route is about 25.5 kilometers (15.8 mi) long and has 30 stations. Of the whole course 17.6 kilometers (10.9 mi) are underground, and the rest is in the open air.[5]

Originally the two planned termini were Pantano (a frazione of the comune of Monte Compatri) in the east and Clodio-Mazzini in the north, but in March 2007, a northward extension along the Via Cassia was announced, with nine more stations up to Grottarossa. A depot has been built at Graniti. The line will cross Line A at San Giovanni and at Ottaviano-San Pietro-Musei Vaticani, and Line B at Colosseo. At Pigneto an interchange will be built with a new railway station on the FR1. At the Colosseo stop a public museum was to be constructed in the station to display archaeological material that was excavated during construction, but the project has been scrapped due to the lack of funds.[6]

The original plan featured a station, at Largo di Torre Argentina, in the city center. However, archaeological remains on the site were even more extensive than expected, and the station was cancelled.[7]


The following extensions have been studied:

  • northward (towards the railway ring around Rome, and the Rome-Viterbo railway, to which it would give access at Tor di Quinto; this extension would have five stations in all and would allow interchange with FR5 at Vigna Clara and Tor di Quinto;
  • a southward extension of one station to Tor Vergata, where a secondary depot might be constructed;
  • a northward extension of the east branch from Teano to reach Ponte Mammolo allowing interchange with Line B, with five new stations. This extension would also meet FR2 at Togliatti.

Rolling stock[edit]

Once completed, the line will be served by 30 AnsaldoBreda Driverless Metro convoys.
