I will be reading whatever is sent quite thoroughly.
In fairness to Merseyrail, once I mentioned that he travelled by that route everyday in the course of his education and it wasn't his form to be disrespectful to the train or its users, the lad on the other end of the phone said that it wasn't a sensible policy to 'criminalise regular rail users'
I would say that if your 'actions' do not actively cause damage to the train or disruption to other rail users that this point is made, either to the bye-law officers on the train or once the first correspondance is recieved.
I also appreciate the difficulty facing Merseyrail, if people are complaining about this, they have to be seen to be doing something.
