On the regional trains it often says no seat reservation needed, mainly seems seat reservations are needed or the Frecciarossa fast trains and regional s often say "Free". Does that mean we just need to show the Eurail Pass to a conductor or do we still need to get something else at the station like a boarding pass or other form of ticket? I am not sure if there are turnstiles that might need us to scan the pass or something else (like a credit card/Metro Card for a NYC Subway systems).
Planning this trip is like learning a brand new job in a different field than you have ever worked in before...
