The British Railways Standard Class 3 2-6-0 was a class of steam locomotive. It was essentially a hybrid engine, the chassis being closely based on and sharing a significant number of parts with the LMS Ivatt Class 4, and having a boiler derived from a GWR "Nº2" boiler (the barrel was shortened by 5 13/16 inches and a dome added) as fitted to the GWR Large Prairie and 56XX 0-6-2 tank engine. The design work was done at the ex-GWR works at Swindon and it was there that they were built with the 2-6-2T version of the class.

Only 20 were built, numbers 77000-19, all at Swindon Works. They were mainly restricted to the North Eastern and Scottish Regions, of British Railways though 77014 was transferred to the Southern Region late in its life. Due to their small number, the class were the antithesis of standard engines and it would probably have been better to build more 2-6-0s to the standard class 4 and standard class 2 designs instead. None has survived to preservation.

Although a BR standard they didn't share the same design of wheels with the Doncaster designed 76XXX Class 4 engines which also had 5'3" driving wheels.
