Hi, the train company in Italy is Trenitalia. Rail Italy never heard.

Trenitalia have started to relese the timetable after the small timetable change in the second sunday in June. But most of the trains are missing. Via Trenitalia.com you can't reserve a seat for Eurail Pass users, but you can look what it is released yet. Best way is via Austrian Railways ÖBB oebb.at, but the new timetable doesn't arivved yet. You will have to wait. There is no rush.
