On 1st April, 2012, I bought a return ticket for £2.45(using young person's railcard) and boarded a train from Welham Green at about 9am to Welwyn Garden city ( a 8min journey). There was a barrier there at welwyn and it clocked one of my tickets(being a two-part journey). I stayed with friends in Welwyn Garden city all day and started heading back at about 9.30pm. On reaching the train station, the train to welham green was for 21.58. Now about 21.52, a train came and I mistakenly entered it thinking it going to take me to welham green. On realizing it wasnt the train i was meant to take, i stopped at Hatfield (note that welham green is two-stops from hatfield) and waited at the platform (note i did not go into the train station) for a train that would take my destination. A station officer came to me while standing on platform and asked for my train ticket rudely, because of how rude he was, I refused to show him my ticket. I also did not show him my ticket because i have never been asked for a ticket on d platform (while not in the train). He threatened to call the police and stop the train. (i was confident because I had a valid ticket and even if the police came, I would show them). When the train for Welham Green, I boarded it and it took me to welham green.After sometime in welham green, i decided to go to hatfield, so i bought a ticket and took a train going to hatfield. On reaching hatfield, the same guy that talked to me rudely before, stopped me again (even with my valid ticket). He called the cops, I dropped my details..I argued that I had a valid ticket for that journey he stopped me for and told I had even another ticket valid from Kings Lynn to hatfield (an open return)..But the cops and the ticket officer wouldnt listen and I was told to show my tickets to the jury if charged. This station officer then told me that a letter could be sent to me if I am going to be charged. A letter has been received and the offence is that i failed to hand over a rail ticket for inspection. The issue now is that I have got to reply, because the ticket came on the 26th, I had thrown away the Welwyn Garden-Welham Green ticket because I thought I wasnt going to be charged again (intention to prosecute). But fortunately, I still have a valid Kings Lynn - Hatfield that would have been OK for the ticket man but that wasnt for my journey :cry: . I need advice, I cant pay any fine because I had a valid ticket, I dont want to have a criminal record because of a rude officer and a paid £2.45 journey . Thanks for ur help...
