The world's smallest trains will be unveiled in King's Cross station on Monday, for a one-day only exhibition.
World-famous miniature artist Salavat Fidai has created micro-sculptures of some of the most iconic trains in the history of British passenger rail travel, including the Flying Scotsman.
So teeny are the artworks that magnifying glasses will be provided, to let people see the detail on the sculptures which is not visible to the naked eye.
The exhibition is put on by Virgin East Coast, to mark 100 weeks until the new Virgin Azuma trains go into service (for the less mathematical among you, that takes us up to 2018, so don't get too excited just yet).
Icons of the East Coast is open for one day only, 3 October 9am-7pm. It'll be situated outside the Travel Centre in the centre of the station and is free.
