'Black Prince' was bought by the North Norfolk Railway from wildlife artist David Shepherd in 2016 and has been a popular sight on trains in recent years.
Friends of Black Prince was set up by railway volunteers to promote and fundraise for the loco.
The British Railways BR Standard Class 9F 2-10-0 is a class of steam locomotive designed for British Railways by Robert Riddles. ...
The last of the class, 92220 Evening Star, was the final steam locomotive to be built by British Railways, in 1960.
As of 2019, three of the locomotives have not been restored to working order since withdrawal: 92207, 92219 and 92245. All were stored rusting in the open air for 20 or more years; parts were removed.
Most have since received at least some cosmetic restoration to prevent them from deteriorating further.
However, the 9F was one of the largest locomotives to run on British railways, and the cost of restoration is high.
