I'm looking to go from Chiusi to Roma Termini on a monday morning. I see 2 direct trains 7:10 and 10:57 but the train time that appeasr to work best for me is the 8:31 listed on Trenitalia. However that run is
8:31 Chiusi - 10:49 Roma Tiburtina (Regionale)
10:59 Tiburtina - 11:14 Termini (Urbano)
What is the Urbano? Are those like the FR1 Communter trains? I know one of the subways links the 2 stations together also. Could Urbano be the subway? I've never been to Tiburtina only the Termini station before.
