Hello, I was hoping someone could offer me some advice. I got the train from Walkden which is an unmanned station at the weekend and the conductor did not come round or was snywhere to be seen whilst on the train to buy a ticket from. When I got off at Manchester Victoria I didn't pass anyone who asked for my ticket so I foolishly didn't purchase a ticket. As I approached the exit of the station I was stopped by a revenues officer and asked for my ticket. He took my details but didn't caution me and said I should expect a letter in the post. I regret not seeking out someone to get a ticket from. What can I expect to happen to me? What will the letter say? Any advice would be gratefully received.
