A train company has launched a "never-ending ticket" which will allow the holder to make a free return journey in first class.
Virgin Trains will randomly select one passenger each day who can use the ticket to travel anywhere on its west coast route.
The operator said it will continue the promotion as long as "the social media community keeps it alive".
To be in with a chance of using the ticket, passengers must send a Twitter message to Virgin Trains with the hashtag #NeverEndingTicket stating where they want to go and why.
Patrick McCall, co-chairman of Virgin Trains, said: "Virgin Trains' never-ending ticket is the first of its kind in the world and will give more people the opportunity to travel to some of the amazing destinations that we have on our route.
"We can't wait for the social community to get in on the game and help the ticket live as long as possible."
Once the holder of the ticket has chosen their destination, Virgin Trains will announce where the ticket is headed and people in that area will have the chance to pick it up and continue its journey.
The promotion will end if the ticket is uncollected or inactive for three separate 24-hour periods.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
