‘Small Prairie’ (2-6-2) tank No. 4566 was built at Swindon and entered service in October 1924. 175 engines of the same basic Churchward design were built, some at Wolverhampton in 1906/8, and some at Swindon from 1909 to 1929. Together with their predecessors, the smaller-wheeled 44XX 2-6-2 tanks of 1904/6, these machines were a common sight on Great Western Railway branch lines for nearly 60 years, and were very popular amongst railwaymen and travellers alike. They were staple power for Severn Valley line passenger services from the early 1920s, the last example disappearing off the route in 1961.
No. 4566 was seen on display in The Engine House at Highley during Severn Valley Railway’s spring steam gala on 20 April 2025.
