The Class 9F was the last in a series of standardised locomotive classes designed for British Railways during the 1950s, and was intended for use on fast, heavy freight trains over long distances. It was one of the most powerful steam locomotive types ever built for British Railways, and successfully performed its intended duties.

In 1919, the Midland Railway built a single 0-10-0 steam locomotive, No 2290 (later LMS (1947) 22290 and BR 58100). It was designed by James Anderson for banking duties on the Lickey Incline in Worcestershire (south of Birmingham), England. It became known as "Big Bertha" or "Big Emma" by railwaymen and railway enthusiasts.

There were 251 9Fs built, 198 at the former LMS works in Crewe and 53 in the GWR’s old Swindon workshops. Black Prince was one of the 9Fs built in Swindon and was delivered to BR on April 6, 1959 – at that time nameless and known only as No. 92203.

The 9F also proved its worth as a passenger locomotive, adept at fast running despite its small driving wheels, and for a time was a frequent sight on the Somerset and Dorset Railway, where its power and high proportion of adhesive weight were well suited to coping with the 1 in 50 gradient on the Bath extension.

BR Standard Class 9F No. 92079 was among one of the 251 BR Standard Class 9Fs built at BR Crewe Works/LMS Crewe Works in 1956 for the London Midland Region of British Railways. It was primarily used as a banking locomotive, it replaced Midland Railway No. 2290 "Big Bertha" and was given Big Bertha 's Headlamp/Electric Headlight after Big Bertha ...

2023年6月11日 · Within 6 years, BR had built 251 9Fs, 198 at the old LMS Crewe works (founded 1840) and 53 at the Great Western’s Swindon works (almost as old, 1841). Glossy and shiny when new, the black soon became caked in smoke and dirt, as the 9Fs earned their keep on heavy coal trains and the faster long distance freights.

2023年3月28日 · Introduced in 1954, the Class 9Fs were the final main line steam locomotives built in any numbers and proved worthy of the role; whilst the other Standard designs were updated replacements of...

The British Railways Standard Class 9F 2-10-0 is a class of steam locomotive designed for British Railways by Robert Riddles. The Class 9F was the last in a series of standardized locomotive classes designed for British Railways during the 1950s, and was intended for use on fast, heavy freight trains over long distances.

The Standard Class 9F locomotives Nos 92020-9 were experimentally built with Franco-Crosti boilers, forming a unique subclass. All ten were built in 1955 at Crewe Works. The Franco-Crosti boiler was designed as a single cylindrical water drum positioned underneath the …

One of the most successful BR standard steam locomotives was the massive 2-10-0, more commonly known as the ‘9F’. These handsome machines proved to be capable all-rounders, despite being intended for heavy freight, as EVAN GREEN-HUGHES remembers.
