The iconic Flying Scotsman steam train is back in service following a £4.2million refurbishment by the National Railway Museum.
And train lovers will be pleased to know that you'll be able to spot the train from various points in west London on Wednesday (May 25).
The train is touring the UK this year, after previously running between Edinburgh and London since 1862.
Flying Scotsman fans have been urged not to risk being injured or electrocuted by getting onto the track to see the train go past after several incidents of trespassing blighted previous tours and put lives at risk.
Since many tracks on the route are electrified, this is a particular risk to anyone who ignores the warnings.
The tour will depart from London Victoria on Wednesday morning, before going through west London and touring around Surrey to finish in Victoria.
