Travel confusion.

We took the train from Baden into Vienna having purchased a ticket that allowed us unlimited travel for a period of twenty four hours at the extortionate price of €19 20 for both of us.  To start with we could not figure out how to verify our tickets, something you are required to do.  We had been on the train for some time and were convinced something was not right, Jan asked a man if he spoke English? he did, and was more than pleased to help, he was very helpful.
