For Italy, please do not use the Interrail app or any other non-Italian app or website because they will be incomplete. The Trenitalia website (or app) is the most complete for Italy.

TODAY = 12/12 all big railways everywhere in EUR change their yearly timetable. In Italy they are always notably very slow to put it in the systems. IF you mean the big printed hang-out tables in stazione-in many countries these are no more.
