I'm not sure that's the case, from what I gather, all of the money goes to the treasury anyway.
I've said it before and I'll say it again, major simplification of fares is the best way forward as it rules out so many grey areas, but I'm also in favour of some form of warning system that is actually backed up with a database, first offence for minor misdemeanor and you get issued a PF but the Penalty element is waived if paid in 21 days on the first time.
Problem is, many people get warned now, but they don't heed the warning and as it's often verbal, they just keep doing it until they get caught and then try playing the victim, for every person I PF/MG there are ten that I "let off with a warning" and sell a ticket.
There also needs to be a standard set by the DfT across all TOC's, the "Admin fee" should be the same everywhere, forgotten railcards process should be the same regardless of TOC, all operators should have PF's as an option.
Revenue Protection policy should be the same as the NRCoT - or even included in it so that it doesn't matter if you're stopped in Carlisle or Penzance (I'll leave Scotland out of this for now), you should be treated the same, firm but fair and with a clear independent means of appeal as a final resort.
