FINES for travelling on trains without a ticket have gone up for the first time in 10 years.
And fare dodgers on train services across West Yorkshire are being targeted.
The Department of Transport has announced that `penalty fares' would increase from £10 to £20.
Penalties are charged by train operators if a passenger cannot produce a valid ticket for a journey on request - either while they are travelling on the train or if they have arrived at a station.
Passengers can be charged either twice the full single fare to the next station stop or the Penalty Fare - whichever is greater.
The Association of Train Operating Companies - which represents train companies - has welcomed the increased penalties.
George Muir, ATOC director general, said: "The Penalty Fare hadn't gone up in 10 years and therefore no longer had the impact it used to have.
"Raising it to £20 should make potential fare dodgers think twice about not paying for a ticket."
Mr Muir said tackling fare evasion was vital, because it costs train operators around £200m a year.
On average, around 3 to 5% of people asked for their tickets have not bought one.
To avoid paying a penalty, passengers must buy a valid ticket to their destination before starting their journey. If the ticket office is closed and passengers cannot buy a ticket for their specific destination from a ticket machine, they are advised to buy a Permit to Travel from the machine.
Passengers insert coins to the value of their journey fare and they will get a permit, which must be exchanged for a valid ticket either with the train conductor or at the next station - within two hours.
At some stations there is no machine or ticket office.
In these situations it is acceptable for passengers to obtain a ticket once they are on the train.
At Huddersfield railway station, staff patrol the platforms to check on tickets.
