GWR 850 Class The GWR Class 850 was an extensive class of small locomotives designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway between 1874 and 1895. Aptly described as the GWR equivalent of the LB&SCR "T ...

dating from 1874. The class pioneer was not a new engine at all, rather it was a 1930 rebuild of 2021 tank 2080. It merely had substitute larger wheels and splashers and a larger bunker, whereas the new locos built from 1931 onwards had the rounded-edge cab as well. This cab style was to be fitted to all subsequent GWR pannier tank designs including the later derivations of the 5700 Class. Despite its success, the prototype had a short life as number 5400, lasting only two years before scrapping. It was replaced with an all-new engine with the same number. 25 locomotives were built and they were numbered 5400–5424.

Withdrawal and mileages

Withdrawal from service with BR started in 1957 and was completed in 1963. The last ones in service were No. 5410, No. 5416, and No. 5420. le Fleming noted that the mileages of those withdrawn between February 1957 and February 1958 were "from 671,000 to 775,000".

This produced two general purpose classes with wide route availability. The 6400 was auto-fitted but more suitable for hilly routes than the 5400. The 7400 was not auto-fitted.
