The Rome–Civita Castellana–Viterbo railway is a regional railway line connecting Rome, Italy, with Viterbo, capital city of the Province of Viterbo. The 102km (63miles) long line, also known in Rome as the Roma Nord line, after its former concessionaire, is part of Rome's metropolitan and regional railway network.
The Roma Nord, a radial route, has its urban terminus at Piazzale Flaminio, on the northern perimeter of Rome's city centre. From there, it runs in a northerly direction, parallel to the Via Flaminia, as far as Civita Castellana, and then to its ultimate destination, Viterbo. Locally, it is derisively referred to as the "Freccia Viterbese".
