Well, in my case I don't think that, nor have a tin foil hat - but I do know that the colleague who worked next to me and used the RHL daily (before lock down) would often say "I've not had to buy a ticket again today - no one came round to check on the train", probably part of the reason he did not have a season ticket I think - and there is a problem for EMT/EMR as to check the side gate exit at Nottm you can only actually check the foot of the stairs up from the platforms (because the bridge and its entrances and exits are Rights of Way anyone can use without a ticket), so the stair foots are wide and have a flight either side, so each island platform (there are 3) needs 2 people at the bottom of each flight so that would be 12 staff in addition to the staff required at the actual concourse gate line.
I'm not saying on board staff should check all tickets, at busy times that was not possible. But I thus believe there is much fare evasion on the RHL.
I can't comment on the Hinckley route but I was surprised to find not ticket machines when I was last at Hinckley - like Burton it's a station that is served by XC but staffed by EMR. I used it on a sat eve, only one occasion but Saturday eve travelers boarded the train, XC did not do a ticket check on that occasion, and there was no barrier check. Reminds me that because a)I'm honest and b) I was traveling beyond Leicester, I went to the ticket office at Leicester to buy my ticket stating origin as Hinckley - but there wasn't a queue of other people who had also boarded at Hinckley that I saw....and I doubt 100% of them had bought a ticket on line before getting on the train!
Also when EMT were on a management contract or whatever it was doesn't that mean that revenue maximization is not really as incentivized as it would otherwise be?
