Tiburtina railway station Rome
At night, while Roma Termini is closed, Tiburtina becomes the main railway station of the city, but also during daytime some important trains arrive there. Tiburtina is a stop on the slower trains of the Firenze-Rome-Napoli railway line and trains to and from places like Pescara and Tivoli also arrive here.
The regional trains FR1 and FR2 (so, including the slow train from Fiumicino) also pass through Tiburtina.
In front of the railway station itself the Piazzale Tiburtina can be found, where you can take local buses to destinations in Rome that are not served by subway line B.
Another square, bigger and at a short walking distance, is the home to the Flixbus company that transports passengers to several medium and long-distance destinations in Italy (and beyond).
