It seems that attempts to avoid paying for fares was present all through railway history, as this snippet from the Ipswich Journal from 1849 shows:
"Attempts to defraud companies of fares appear to become more frequent. During the past week three cases have occurred. On the Chester and Birkenhead, John Fitzsimon was fined 10s and costs for attempting to avoid the fare at Beddington Station. A greengrocer, who tried to travel free, and made his escape from Liverpool to Wolverhampton, by the London and North Western, was fined 40s. or, in default of payment, 14 days' imprisonment; and a young man who jumped out of a train without a train before it stopped at Reigate, was fined in a penalty 20s. and 14s. costs by the local magistrates."
