Although Line A opened after Line B, it is called Line A because it was originally the longer of Rome's two subway lines. Line A first opened in 1980, operating from Anagnina to Ottaviano. The line was extended to Viale Aurelia on May 29, 1999, and to Battistini on January 1, 2000. The line is now 11.8 miles (19 kilometers) long, all of which is underground aside from when the line crosses the Tiber River between Flamino and Lepanto, has 27 stations. The line is served by CAF MA300 Stock. These Spanish built trainsets have articulated cars that allow easy movement from one railcar to the next, automated announcements, LED displays that show the name of the next station, TV screens in each car, and CCTV.
