Hopefully you might be able to give me a bit of help / advice 
I am a rail commuter on the GWR network and recently travelled from my home station, which we shall call station A, to my work station, which we shall call station C. Both are penalty fare stations and a ticket is required.
My monthly season ticket had expired, there was a long queue at my home ticket station where the ticket machine was out of order, so i naturally assumed i would be able to buy a day ticket from the train manager after boarding. Unfortunately, the train was too busy that the manager couldn't move up and down the train to check or sell tickets. On arrival at my destination (station C) i went to buy a ticket, but unfortunately I had a moment of madness and told the inspector i had actually travelled from station B, in order to pay a reduced fare. Station B is nearer my final destination than my home station (A).
I was then referred to a revenue protection officer who after a brief discussion realised I lied and had actually travelled from station A (my home station). The officer then opened a little black book, cautioned me and asked me to confirm and sign all the details and advised I would receive a letter shortly. I was told i will be asked to explain my actions.
My worry and concern with this is - do you think this scenario would typically allow itself for an out of court settlement, avoiding prosecution and the possibility of a criminal record? I am more than happy to pay for the ticket, GWRs expenses and compensation for this stupid decision on my part - but how much might this amount to?
