A new campaign has been launched to try to reduce fare dodging train passengers.
Northern Rail has launched two online videos and a series of posters to remind people to pay for their journeys.
Last year, 652 passengers were caught travelling without a valid ticket.
Alex Hynes, managing director of Northern Rail, said: “We know from talking to our customers they have a real problem when they see others not paying for their journey.
“We don’t want to see passengers getting into trouble. We want to make sure they understand the implications of taking a free ride.
“We hear all sorts of excuses from passengers as to why they don’t have a ticket – they don’t have any money, or a conductor did not come down the train to sell them one.
“But it is the passenger’s responsibility to buy a ticket so they must seek out the conductor or, if that is not possible, buy a ticket at their destination station.”
