So, I was looking to travel Genova to Ventimiglia and used the rail planner app. All trains shown required reservation. I followed link to https://www.eurail.com/en/book-reservations with intention of making a reservation for this route and several trains NOT requiring reservation also appeared e.g.
RE 3360 Regional operated by
Ferrovie dello Stato SpA
Direction
VENTIMIGLIA
Why do these not appear in planner when "eurail" obviously does know about them. Do they "really" exist?
