With two other New Zealanders I am planning to do the River Rhone cycle route starting late in June. In order to get to the start of the route (Furka Pass), we plan on Thursday 27.6.2024 to take the train from Zűrich HB to Oberwald (probably the service departing at 10:02, with 1 change at Brig). Will we be able to place our bicycles in racks on the train in ready-to-ride state, or do the bicycles need to be dismantled and packed in boxes for the journey?
