Staff at Wrexham railway station had a shock when a man turned up and demanded to buy a train ticket - for his pony.
Despite being told that horses were not allowed on the train, he bundled the animal into a lift and led it onto the platform.
When the train to Holyhead on Anglesey arrived, the man attempted to board it with his pony, but was stopped by a conductor.
The Daily Post quoted a source as saying: "The man took the pony into the ticket office and asked for a ticket. He was refused and told that no horses were allowed on the train.
"But he said 'I know the law' and walked away. He got into a lift with the horse and walked it across the bridge and onto a platform.
"He waited for the train to arrive and then got on himself and was in the process of trying to pull the pony on after him when the conductor stopped him.
"Staff couldn't believe it - most people thought it was a wind-up."
The man is believed to have left the station, with the pony, after a brief argument.
An Arriva Trains Wales spokeswoman said: "Obviously passengers are not allowed to take livestock on to the train.
"We do allow small animals, such as dogs and guide dogs, onboard but not large animals that could pose a risk to the general public."
