Line B is a metro line serving Rome, Italy, and part of the Rome Metro. Despite its name, Line B was the first line to be built in the city. It crosses Rome diagonally from north-east, starting at Rebibbia and at Conca d'Oro stations, to south, terminating at Laurentina, in the EUR district. It crosses line A at Termini station. The line has 25 stations and is shown in blue color on Metro maps.

Overview[edit]

Its first service runs at 5:30am and its last at 23:30. From 18 January 2008, the last Friday and Saturday service runs at 1:30. It carries 300,000 passengers a day and runs 377 trains a day, with a peak time frequency of one train every 3 minutes and one every 6 minutes at other times, at a maximum frequency of 10 minutes at the most off-peak times.[2]

History[edit]

Notwithstanding its name, the B line was in fact the first metro line in Rome. The line B connects the northern quarters of the city with the south-west. It currently has 25 stations with terminuses at Rebibbia, Conca d'Oro and Laurentina (just east of EUR). It is distinguished by the colour blue.

The B line was planned during the 1930s by the Fascist government in search of a rapid connection between the main train station, Termini, and a new district to the south-east of the city, E42, the planned location of the Universal Exposition (or Expo), which was to be held in Rome in 1942. The exposition never took place due to Italy's entrance into the Second World War in 1940. When work was interrupted some of the tunnels on the city-centre side of the metro (between Termini and Piramide) had been completed and were used as air raid shelters during the war.

Work on the metro began again in 1948, in concert with turning the space, formerly designated for the Expo, into a commercial district under the name EUR. The metro was officially opened on 9 February 1955 by the then President of the Republic Luigi Einaudi. Regular services began on the following day.

In 1990, the B line was extended from Termini to Rebibbia to the east of the city, and the entire line was modernised. A spur called the B1 line opened on 13 June 2012.[3] It is a branch of Line B from Bologna to Conca d'Oro with 3 stations: Sant'Agnese/Annibaliano, Libia and Conca d'Oro.

Extensions[edit]

After the recently opened B1 line, which is being extended beyond Conca d'Oro to Piazzale Jonio (and then to Bufalotta),[4] another future extension has been planned beyond Rebibbia with 2 stations: San Basilio and Torraccia/Casal Monastero.[5]

Rolling stock[edit]

When the B line opened in 1955, MR100 and MR200 trains (also collectively known as Automotrice Stanga-TIBB) were used, and were retired in 1990. Similar trains were also used on the Rome-Lido railway, and some still continue in that role today.

Nowadays, the B line mostly utilise AnsaldoBreda built MB100 trains. These were introduced in 1990 not only to replace the ageing MR100 and MR200 trains but also to cope with an increase in passengers following the opening of the eastward extension to Rebibbia. These cars are heavily graffitied, giving the B line's rolling stock the appearance of New York City Subway rolling stock during the 1970s and 1980s. The MB100 cars are due for rebuilding at a future date.[6] A fleet of trains similar to the MB100 trains were also built for the Lima Metro in Peru.

Also used are the newer CAF MA300 trains similar to those on the A Line running in B line service. These MA300 trains entered service on the B line in 2010.
