I have been searching the Trenitalia website for a timetable for a train from Venice to Rome in January. It is only coming up with one option which is departs ar 3.11AM. I find it odd that it only shows one train, I know there would be more than that. Is this because I am looking too far in advance? I am wanting to book a number train trips in Europe for Dec/Jan is it best to book through the train companies website or are there better alternatives.
