A technical glitch has been blamed after first class train tickets between two towns 64 miles apart were reportedly being sold for £10,000.
The price is said to have been quoted for a ticket between Taunton, Somerset, and Trowbridge, Wiltshire, to travel on June 20 - £9,987.30 more expensive than the standard class fare.
The journey would cost around £156 a minute for the trip which includes a change at Westbury.
Screenshots of the error have been shared widely on social media - with one Twitter user saying the sky-high price would be considered normal in the capital.
User Daravel_Fox said: "£10,000 first class railway ticket. Sounds like standard prices for via London trains."
While Ryan Laird tweeted: "I knew UK train prices were bad at times but £10,000 for a train ticket?"
Another user, SomersetSunshin, said: "£10,000.00 for a 1st class return ticket from Taunton to Trowbridge on your website, is that a joke glitch?"
A Great Western Railway spokesman told the Wiltshire Times: "We are aware of an IT glitch which has published fares for a first class journey that does not exist.
"We are working to remedy this as soon as possible.
"Anytime single fares between Taunton and Trowbridge are available from £12.70."
