Trenitalia is always late publishing timetables, especially for their night trains and regional trains.

Check regularly on www.trenitalia.com; that's where they will appear first.

Thanks - I was more worried about the fast trains - regional are appearing however the fast are not

Yes, for regional trains Trenitalia is now faster with publishing. But with long distance trains they need often more time. Because there can be works at the line and because Trenitalia is very slow with publishing their timetables.
