I have received a letter from TFL for failing to produce a valid ticket, pass or photocard for my journey the London Underground.
have asked for my side of the story and have been advised that legal proceedings may be taken against me.
What happened is that I was on the tube then an inspector came on and I gave him the Oyster card that I had used for the journey.
He scanned it and asked to see the railcard attached so I gave him my student railcard.
He then told me that there is a greater discount on the card and asked if I have another railcard.
I said that I don't.
