So of course I know Im stupid and accept full blame. For the past maybe 2-3 years I have been using a 16-17 railcard and i purchase shorter destinations as there are no barriers where I live. For the past 3 months I have been purchasing clapham junction to vauxhall on a 16-17 railcard and have been caught. When I got caught I panicked and lied and said I travelled from Twickenham when I always travel from Ashford. I do however have a 16-25 railcard which I showed. They scanned my e ticket so of course will be able to see my purchase history. I am extremely scared and worried as I never realised what I was doing was criminal. I know I am going to be looking at a huge fine. Would anyone know how much I would be looking at so I can start saving? just a rough estimate? and will I go to court straight away or an interview? I know I am completely stupid but I have been doing this for basically every journey I take and I am so scared of the consequences.
