How do you tell what the car numbers are? For example on order #127462263 I am traveling from Zurich Flaghafen to Olten of my first leg TO Zermatt and have seat reservations in car 2, seats 25 and 26. How will I be able to tell which car is car 2 at the station? Same thing on the Bern to Visp leg, how will I tell which is car 9 at Bern? Thanks for any assistance.
