My train travel is mostly on SWR and GWR, and on both it seems to me that almost all the add-on messaging (i.e. other than the necessary stuff like route and stops) is relentlessly negative. It's all focussed on don't do this, or this is how we'll punish you if you do that, or you should report someone if they do the other. The impression it gives is that their trains are a hotbed of risks, fare evasion and crime, and while this might be the case in some locations at certain times, it isn't most passengers' daily experience. When I see ticket checks being carried out, it's very unusual to see anyone picked up for no ticket or wrong ticket. Maybe I'm just lucky in using law-abiding routes - even loud music or loud phone calls are very rare, I'm happy to say!
