A man from Wrexham has been criticised by the RSPCA for trying to board a train with a pony.
CCTV images captured the event, which shocked passengers and staff alike.
The man attempted to buy two tickets – one for himself and one for the animal – but Arriva Trains Wales said it was not safe to transport the pony in such a way.
In response, the animal charity told the BBC that commercial passenger rail is "not a safe or acceptable" means of transporting an equine.
"The pony could have been injured or could have caused injury to passengers," it added.
People wishing to travel with (small) animals may want to consider a train journey, as most major airlines are now charging much more to transport pets in the cargo bay, according to the New York Times.
In a statement, the RSPCA said of the station incident it was "not a safe nor acceptable manner in which to transport an equine."
