The Caledonian Railway's book of standing orders for the officer's and men of the company from 1863 is one of the most interesting railway instruction books that I have a digital copy of, as it contains rules that I have not seen anywhere else within the Victorian railway industry.

If there are more than one, they must all be locked up in one compartment, and never allowed to change carriages: and whenever they are discovered to be without tickets, or travelling beyond the station for which their tickets were issued, they must be removed from the train, and prosecuted before a magistrate for defrauding the company.
Ticket clerks must be cautious in receiving money from these men, as they endeavour to pass base coin and forged notes.'
