Hi everyone, On Thursday morning I took the Great Northern Line from New Southgate to Moorgate. I had £2.10 on my Oyester Card already, but because I was in a rush and was late, I boarded the train without swiping my Oyster Card in first. When I reached to Moorgate station, the ticket inspector checked my Oyster Card as Invalid Ticket and I mentioned to him that I missed swiping in. I offered to pay the full fare there and then and I even offered to pay any penalty fare there and then. Instead the officer to my details down from my driving licence, and asked me a few questions and told me to sign the paper and stated that I will receive a letter in three weeks time and can explain to them. This is the first time this has ever happened to me, as I always pay my fares. Please could someone tell me what this letter is. I am willing to pay the penalty fare. I do not want any problems. I do not want to be prosecuted or taken to court - I am willing to pay the Penalty fare. Please can someone help me - i have been so upset since. Why wasn't I charged the penalty fare? I spoke with two TFL staff and two Great Northern Line staff and they stated that I should've been charged the penalty fare. I have also emailed Great Northern Customer Services about this as well. Can I have an out of court settlement if worse case comes ? Please can someone help me!
