Except for the fact it wasn't a paper ticket, it was an electronic ticket which likely has all sorts of records and metadata connected to it as well as being verifiable via a server - which would be needed anyway otherwise they have likely a huge electronically generated counterfeit or an accounting problem. I'm guessing if the police wanted to check an alibi of an individual claiming to have taken the train at some point that the records of that electronic ticket would be dug up.
