The Metro comprises three lines –
A (orange),
B (blue) and
C (green) – which operate on of route, serving 73 stations.
[Counting Termini, the interchange station between Lines A and B, and San Giovanni, the interchange station between Lines A and C, only once.] It has a daily ridership of approximately 820,000 passengers, and an annual traffic of approximately 320 million passengers.
In addition to the Metro, the center of Rome and its urban area are served by 8

Leonardo Express'' which connects
Roma Termini, the central station of the city of Rome, to the
Leonardo da Vinci Airport of
Fiumicino, and the ''Civitavecchia Express'' which connects the city to the main port of Rome, the
Port of Civitavecchia. Network extensions are currently under construction on Line C (
Porta Metronia,
Colosseo-Fori Imperiali and
Venezia). There are further projects for Line A, Line B, Rome-Giardinetti and for the suburban rail system. The entire transport system in Rome uses the
Metrebus integrated tariff system (an acronym composed of the words "Metro", "Train" and "Bus"), which can be used within the limits of the Municipality of Rome and within the limits of the urban tariff.
Line B was the first metro line inaugurated in the system, and the first official metro in Italy, but the names 'A' and 'B' were only added when the second line opened 25 years after the first. Inaugurated in
post-war Italy in 1955 during the reconstruction and on the verge of the
Italian economic miracle, it was designed and built for the 1942
universal exhibition (''
Esposizione Universale Roma'', which is now the current business center of Rome) desired by the
fascist regime, which never took place due to the outbreak of the

Lines
Line A
Line A runs from the southeastern suburbs of Rome, then along the northeast section of downtown, and then to the northern section of the city, near Vatican City. It connects with Line B, along with many other national and regional rail services, at Termini, and with Line C at San Giovanni. It has 27 stations, with terminals at Battistini and Anagnina. It is identified by the colour orange.
Line A was the second line built in Rome. Approval was given for the construction of the city's second Metro line in 1959.
Work on Line A began in 1964 in the ''Tuscolana'' area, but suffered a series of delays caused the originally planned
cut and cover method of construction posed serious problems for road traffic in southeast Rome. Work on the Metro was suspended and began again five years later, using bored tunnels, which partially resolved the traffic problems but caused numerous claims for compensation for vibrations caused by the machines. Work was also frequently interrupted by archaeological finds made during the excavations, particularly near
Piazza della Repubblica.
Line A entered service in February 1980. In the late 1990s, it was extended from
Ottaviano, in the
Prati district, to
Battistini to the west.
Since June 2022, the station of Valle Aurelia, on Line A, is connected with the reactivated railway station of Vigna Clara. The Vigna Clara-Valle Aurelia section is a relevant step to close the railway ring in North Rome because of the connection with the Line A, Line B (Ostiense) and the
FL3 suburban line to

Line B
Line B was the first Metro line in Rome. Line B connects the northeast of the city with the southwest. It has 26 stations with terminals at Rebibbia, Jonio and Laurentina (just east of

). It is identified by the colour blue. Transfers are available with Line A and other rail services at Termini station.
Line B was planned during the 1930s by the fascist government to provide a rapid connection between the main train station, Termini, and a new district to the southeast of the city, E42, the planned location of the

. Regular services began the following day.
In 1990, Line B was extended from Termini to Rebibbia in the east of the city and the entire line was modernised. A new long branch (B1) was opened connecting
Piazza Bologna with
Conca d'Oro on 13 June 2012; the branch's last stop (and new terminus),
Jonio, was opened on 21 April 2015.
Line C

Opened on 9 November 2014, line C currently runs radially from
San Giovanni, serving as an interchange station for Line A, to the eastern terminus of Pantano (the former terminus of the Roma–Giardinetti light railway). It is the first Metro line to extend beyond the city boundaries in Rome.
It is planned to extend to the northwest, towards Grottarossa (north of the

), via the city centre; it will also intersect with Line A at Ottaviano (beside the Vatican), with Line B at
Colosseo, and with the planned Line D at
Piazza Venezia, thus creating a fourth Metro hub in Rome.
The first section of the line, from
Centocelle to
Pantano, is the furthest from the city centre and includes 15 of the planned 30 stops. A further section of Line C, serving six additional stations, opened on 29 June 2015, as the line's western terminus was moved from Parco di Centocelle to
Lodi.
On 12 May 2018, the western terminus was moved to San Giovanni (interchange station for line A). After this third phase, the line will be further extended with three stations, Porta Metronia, Colosseo, and Piazza Venezia, located in the city centre.
Progress on the line has been slow with projected completion dates being repeatedly delayed. Rome is one of the oldest cities in the world, and as such, the construction of the Metro system has encountered considerable obstacles owing to frequent archaeological discoveries. While the excavation of the tunnels themselves can be undertaken well below the probable location of most archaeological finds, the excavation of stairwells and ventilation shafts – which must, by necessity, connect with the surface – pose considerable difficulties.
The trains operating on line C are completely automated, and use the same
AnsaldoBreda Driverless Metro system also featured on the
Copenhagen Metro.
Archeostation
During the excavation for the central route of line C, thanks to the archeological richness of Rome's ground a new type of underground station was born, as in Paris with
Louvre–Rivoli station.
San Giovanni
San Giovanni station was the first archeostation to be opened on 12 May 2018. Excavation to a depth of about 20 metres allowed the exploration of about 21 stratifications of history up to the so-called virgin soil, the one in which man's presence is absent.
The exhibition is characterized by being a real tour with libraries for the finds along the route, explanatory panels on the walls and a temporal measurement of the historical phases that follows the path of the passengers from the atrium level to the platforms' level:
* Atrium level: from ''Contemporary Age'' to ''Late Antiquity Age''
* First underground level: from ''Republican Age'' to ''Archaic Age''
* Platform level: ''Prehistoric Age''
The various archaeological finds and exhibits include small items such as gold jewelry, coins, crockery, shells, large amphorae and elements of ancient columns and also large finds, such as the large pool, the largest reservoir ever found, located inside a farm of the imperial age.

Rolling stock
All Rome metro lines are
heavy rapid transit lines, with 6-car trains, approximately 105 m long. Line A of the Rome metro uses exclusively the
CAF MA 300 series, line B essentially uses the CAF MB400 series together with other CAF MA300 series trains and the historic MB 100
Ansaldobreda. Line C is the longest driverless metro in Italy and one of the largest in Europe, using
Hitachi Rail Italy's driverless technology.
Service
Fares
An urban single journey ticket (
integrated ticket), the ''Biglietto Integrato a Tempo'' (BIT), costs €1.50, and is valid on the Metro, buses,
trams and
suburban trains inside the Rome municipality for 100 minutes from first validation. Other tickets are available, including daily (€7.00), 2-day (€12.50), and 3-day (€18.00) passes (Rome 24h/48h/72h), and a weekly pass (€24.00), the ''Carta Integrata Settimanale'' (CIS). Monthly passes that are valid during the charged calendar month for unlimited journeys available for the personal usage (€35.00) or impersonal usage (€53.00) and may be used alternatively by different persons. Children under 10 years old travel can travel for free on public transport services when accompanied by a fare-paying adult.
Two proximity cards are available in Rome, ''”èRoma”'' and ''”
Metrebus Card Red”,'' which can be charged with season tickets, replacing paper for this type of ticket.
Operating hours
Service starts at about 5:30 am and ends at about 11:30 pm. On Fridays and Saturdays service ends later, at about 1:30 am.
When the Metro is closed, a night bus service operates with lines that follow the same routes and stop at the same stations as the Metro. Line A is served by bus NMA, Line B is served by bus NMB/NMB1, and Line C is served by bus NMC.
Other rail lines

Rome's local transport provider,
ATAC, operates the Metro network and the
Rome-Giardinetti line. The
Roma–Lido, which connects Rome to
Ostia, and the
Roma–Viterbo line, used to be operated by ATAC until 1 July 2022, when it became part of the
Cotral network.
Roma–Lido
Construction of the Roma–Lido line began shortly after the end of
World War I

and was completed some six years later in 1924. It began operation as a steam locomotion railway but electrification was completed less than a year later.
The line is operated as an integrated part of the Metro, but runs entirely overground. It runs from the ''Roma Porta San Paolo'' station beside the Line B ''Piramide'' station and runs alongside Line B as far as EUR Magliana. It then continues separately on to the seaside district of
Ostia. The line terminates beside the end of ''Via Cristoforo Colombo''.
Roma–Giardinetti
Officially termed a railway, the Roma–Giardinetti line is a narrow gauge tram which connects Laziali (a smaller, local train station some 800 metres east of Termini's main concourse) with Giardinetti, just past the ''Grande Raccordo Anulare (GRA)'' – Rome's orbital motorway. The line originally ran to
Frosinone some from Rome, but has been gradually reduced in length, when the section from Giardinetti to Pantano, which will become a permanent part of Line C, was taken out of service. Most recently also the part from Centocelle to Giardinetti was reduced.
As regards future projects, the transformation of the line into a
modern light rail line is planned, with an extension planned to the
Tor Vergata area. The new light rail system will be called "line G" with respect to the metro network and line 11 with respect to the tram network. The work, after a long bureaucratic process, has been commissioned and financed, the line is expected to close during 2026 in order to begin work.
Roma–Civita Castellana–Viterbo
The Roma–Civita Castellana–Viterbo line (also called Roma Nord railway) began life as a narrow-gauge tram running from ''Piazza della Libertà'' in Rome to

Future expansions
The Metro system is currently expanding:
* An extension of ''line A'' from
Battistini to ''Torrevecchia'' towards the west of the city is planned; a track of 2 kilometres (1.2 mi) with 2 stations.
* An extension of ''line B'' is also planned. A track of 2.8 kilometres (1.7 mi) with 2 stations should be realized from
Rebibbia (Rome Metro) to ''Torraccia/Casal Monastero'', towards the east of Rome. The extension of the line B1 is extending from Jonio to Bufalotta with 3.8 kilometers with 3 stations.
* The extension of ''line C'' towards the centre of Rome is under construction. From
San Giovanni (interchange station with line A) to
Grottarossa (Rome Metro), the track is 3.6 kilometres (2.2 mi) long with an intermediate station near
San Giovanni Addolorata Hospital, ''Amba Aradam''.
New lines

There are two proposed new lines, with no timeline for their construction:

Signalling
Signalling of the Rome Metro guarantees trains' safe and correct movements.
Line A
Line A uses an evolution of the
RS4 Codici
RS4 Codici is a train protection system used in Italy. The term is an abbreviation of ''Ripetizione Segnali a 4 codici'' (''signal repetition system with 4 codes'').
It is a simple cab signalling system, displaying the aspect of the next (and, ...
, a classical block system of the Italian railway. Since its creation the signalling offers to the conductor advice about the speed limit and the freedom of the way.
Line B
Until 1990,
Line B used a railway-like signaling system that advised only about the freedom of the way.
Since 1990, the line uses a new signaling system, inspired by the
Milan Metro's signaling, that gives information about the speed limit in the section within a range of 0 km/h and 80 km/h. Conductors are informed by classical light semaphores.
Line C
Line C is an automatic line and uses a radio frequency system for communication with the train. It has an electrical block system that permits a max frequency of a train every 90 seconds.
