Will be travelling on the Westbahn this summer , and when I used it last year I was able to use my Bahncard at the time to get the discounted WESTvorteilspreis ticket. On the Westbahn site it says this ticket is valid for any railway discount card. As my Bahncard has now expired , would I be able to use my 16-25 Railcard with a discounted ticket, or would I run into problems with this during ticket checks on the train?
