Hello casualvisitor
You should not post PNR numbers on a public forum, that’s unsafe. It could be abused.
We cannot answer the question because we cannot access your ticket.
Have you got the tickets, too? French railways sell online tickets which must be picked up at the railway travel office in France before boarding. Check if that is the case with your tickets, please. Travelling with the PNR is not sufficient, you need tickets with a QR code.
If you need further help, please call the SBB Contact Center: +41 51 225 78 56, 24/7, waiting times may occur.
Best regards,
Roland
