Returning from Birmingham New Street on a Cross Country Service earlier today I was caught rubbing the stamp off a ticket after it was returned from the train conductor. After the ticket was returned the stamped was smudged and I was curious as to how easy the stamp rubbed off, I proceeded to rub off the stamp completely only to be caught by the conductor. The conductor asked to see the ticket again and simply asked 'Why did you rub off the stamp?' I answered that 'I did not know why I had rubbed off the stamp and did not intend to reuse the ticket.' As the ticket was a Young Persons railcard I also produced my railcard upon the first inspection of the ticket. I may be over worrying after reading other posts on this forum however please could you advise ihf any prosecution is likely to take place? All details of the event are given above. I was never interviewed or asked any other questions nor was I told my actions could lead to a prosecution. As the ticket was purchased online I was worried that any details requied could have been obtained by the conductor when he inspected the ticket or the railcard? Thank you in advance for your responses.
