I am trying to forward plan above training trip applying my Eurorail Pass checking if reservations needed. When I search on Eurorail site eurorail.com it gives me NO train options for Castiglion Fiorentino to Florence and states I need reservations X 2 for Florence to Interlaken West. On the other hand when I search trainline.com it gives me non-seat reservations options for Florence -Interlaken travel.
I need to do similar rail plan to return from Interlaken West to Rome Fiumicino Airport 16/7/23 (not Tuscany this way)
How can I plan with Eurorail's search result here? Advice needed please as to whether I need to apply Reservations (or not) against the 7 day Eurorail Pass I have purchased.
