Rome, Italy - Rome Metro HD (2015)

The Rome Metro (Italian: Metropolitana di Roma) is an underground public transportation system that operates in Rome, Italy. The network opened in 1955, making it the oldest in Italy. The Metro comprises three lines – Line A (orange), Line B (blue) and Line C (green) – which operate on 54.7 kilometres (34.0 mi) of route, serving 68 stations.[1] The original lines in the system, Lines A and B, form an X shape with the lines intersecting at Termini Station, the main train station in Rome. Line B splits at the Bologna station in two branches. Line C is not yet connected to the rest of the Metro network. Plans have also been announced for a fourth line, Line D.

Rome's local transport provider, ATAC, operates the Rome Metro and several other rail services: the Roma–Lido line, the Roma-Giardinetti line, and the Roma–Nord line. The first of these, the Roma–Lido, which connects Rome to Ostia, on the sea, is effectively part of the metro network. It is run on similar lines and uses trains similar to those in service on the Metro. The Roma–Giardinetti line, although designated as a railway, is a narrow gauge tram line, while the Roma–Nord line is a suburban railway.
