The BR Standard Class 9F was developed by Robert Riddles as a heavy freight locomotive intended to maintain high speeds over longer distances. A total of 251 9Fs were built in Crewe and Swindon between 1954 and 1960. The last steam locomotive BR built was a 9F. She was christened the Evening Star and given the Brunswick Green livery normally reserved for Express passenger locos. The 9F was considered very successful and was even used for passenger services in some parts of the country. During her relatively short service, attempts were made to further improve the design, for example with Franco-Crosti boilers and preheaters. On the whole these attempts were not considered very successful, the only exception being the later addition of a double chimney to the design, which was fitted to all locos from 1957 onwards and which was retrofitted to some older locos. Several 9Fs survive, including the Evening Star, which is in the NRM in York.
