I’m traveling from Geneva to Bern on May 11, 2026 using my Global Eurail Pass. I would like to take the scenic route on the Golden Pass Express from Montreux to Spiez. Is the Global Eurail Pass still valid on all Golden Pass Express routes during 2026? Are seat reservations required or optional? Is there a chance that the train will be full if I do not reserve a seat? When I query a route from Montreux to Spiez via Zweisimmen, the Panoramic Express portions of the trip all note “Seat recommended.” Presumably this means seat reservations are optional. There is also a note that indicates that “Reservation fees vary based on the route,” but I’m not sure what this means. Any clarification would be appreciated.
