New variation today. “If you see something which you are unhappy with and don’t want to talk to the onboard team you can text BTP on 61016 and they will meet you at the station you ask them to”.
Good luck with that.
You can be asked questions via the same text service, and depending on the conversation there's no reason that very scenario can't happen. I've been called and asked if the people are still onboard, and where on the train they are, to have the police waiting and ready when it arrived at a large station they were based at/near.
