I will preface this by saying I do not in anyway condone fare evasion, but I have read enough stories on this forum to know that they are not all due to the passenger. I must admit have never seen one from a current TOC, I am not here talking about uniform staff, guards etc but plain clothes RPI's. Back in the days before TFL operated to Clapham Junction I was asked by a London Underground RPI for my ticket to access the platform on the Southern from the bridge. I suggested his LU id in this instance was about the same as my airport one. He said he had been seconded and his supervisor was called who apologised and said he should have been given a letter to show his secondment along with his id. Now on the tube where I saw them in action a few times, they usually put on an id as the train pulled out of the station. Do TOC ones work the same way? Do I have a right to demand to see an id if one is not presented to me? Do I have the right to demand and take down the name of the person? Am I allowed to record video or photograph and conversation? It would appear from the dispute threads that the TOC will never go against the view of the RPI so this would appear to be the only way to achieve accuracy. I do realise that most RPI's would follow the rules but any group will have individuals who are not so well trained, are just difficult, or do not follow the rules. I see the same with the Dorset Council parking enforcement officers who do not follow the Dft parking regulations,seem to make up rules on the hoof and when challenged (by me as a concerned resident, not the vehicle owner) get met with "because we can" or "that's what we do" type responses. Even contacting the council generates zero response. It is always good to know where you stand.
