electric train Breda MA100 (4 elements in configuration [M + M + M + M], 71 feet, 808 seats), 1975 / 79 (001-152 MA ACOTRAL group of 38 trains), on line A. Pietro Nenni bridge in autumn 1987.
Following the convoys were expanded to 6 items (configuration [M + R + M + M + R + M], 107 meters, 1,272 seats) with the purchase of 76 trailers (group RA 001-076).
For the Great Jubilee of 2000, the fleet of rolling stock was expanded with the acquisition of 8 electric trains Ansaldobreda MA200 (in configuration [M + R + M + M + R + M], intercom units 3 to 3, 107 meters and 1,220 seats) .

the map of Rome as the network currently (spring 2010). The network is composed of only two lines: Line A, red (Anagnina - Battistini), line B, blue (Laurentina - Rebibbia). There is only Terms node interchange between the two lines.
underground lines can be likened to the surface also the Rome-Lido (Pyramid-Cristoforo Colombo) (line E), the urban section (Flaminio-Montebello) the railway Roma-Civita Castellana-Viterbo (line F) and survived the urban section (Roma-Lazio Gardens) of RAILWAY-Rome-Fiuggi Frosinone . With this assimilation interchange nodes become 5, even if they do not contribute to a real increase of the 'network effect'.
