Hello, I'll be in Switzerland next month and will be traveling from Lausanne to Interlaken with 4 friends. We would like to ride the Golden Pass panoramic cars to Interlaken, but we were unsure of what kind of ticket we need (we will not be traveling around Switzerland enough to make a railpass economical).
Will a "regular" 2nd class ticket from Lausanne to Interlaken get us on the panoramic cars, or do we need a "special" Golden Pass ticket? If we need a special ticket, can we buy it in Lausanne or do we need to get it in Montreaux (where the Golden Pass appears to start)?
Any and all help is greatly appreciated! Thank you in advance!
