Hi all. A little background. Purchased the Swiss Half Fare Fare from Rick Steves/Rail Europe for our July trip. Plan to use purchasing online ticket from Milan to Lauterbrunnen. Prior to purchase emailed Rick Steves office and they confirmed can validate on the train via the conductor. Had also emailed SBB and they confirmed can use the card to purchase online and don't need it validated.
Just received the card and being extra cautious I emailed Rail Europe and have been told that I can't validate on the train but have to do in the station. So, I emailed SBB again and sent a photo of the card. They told me I can have this version of the Half Fare Card validated on the train by the conductor.
So..... I would like to avoid issues on the train so wanted to ask if anyone has had experience getting this particular version of the Swiss Half Fare Card validated on the train. I've emailed SBB again with Rail Europe's answer and also emailed Rail Europe the SBB answer. Thanks for sharing feedback on your experiences with this!
