It seems to be pretty obvious that many of the TOCs are attempting to discourage travellers from using services, and as long as they do that within the constraints and allowances in the legislation I think that is fair enough. It becomes a problem when they attempt to go beyond the law, especially as they are running a de facto public transport service that is funded by the government - on that basis, I do not believe that such private companies have a right to restrict access beyond what the current regulations permit. The elephant in the room of course is that niggly rule that makes it an offence to ignore or disobey instructions from railway staff. So if a TOC, of just an individual staff member, goes beyond the legislation and takes matters into their own hands by trying to restrict legitimate travel, the prospective customer is put in a very difficult position. Its all very well saying take names, report the problem, etc, but that doesn’t really help the person who might have a need (or even a desire) to travel immediately.
