The 5700 class were introduced in 1929, whilst the 8750 class followed in 1933 and by 1950 863 locomotives had been constructed, making this perhaps the most successful 0-6-0. G.W.R. Classification: Group C, Route Blue, changed to yellow under B.R. B.R. Classification: 3F. Designed for shunting and short freight workings, however it soon became clear that other duties could be performed such as branch passenger working and mainline freight, being widespread across the system.
The 8750 class can be distinguished from the 5700 class by the totally enclosed larger cab. Whistle shields and bunker steps with handrails were added from 1936. A new water feed was introduced in 1942 with the clack valves being fitted inside a case on top of the boiler in front of the dome, which became standard for builds after 1944. Between 1956 and 1963, thirteen 5700 locomotives were sold to the London Transport being painted in the attractive lined red livery. The NCB bought five 5700 locomotives between 1959 and 1965, with number 7754 still working in 1975.
