'''4566 ''' is a '''GWR Churchward 4500 class 2-6-2T '[[Whyte notation|Small Prairie]]'''', one of a class of 175 small mixed traffic locomotives mainly used on branch lines. A further 100 Collett 4575 Class small prairies were also produced with larger side tanks giving increased water capacity. They used the 'Standard 5' GWR boiler and were rated Yellow C under the [[GWR Power and Weight Classification | GWR system of power and weight classification]] and 4MT under the British Railways system. Small prairies were a common sight on the Severn Valley Branch from the 1920s; the last use there being in 1961.<ref name = "SB9">SVR Stock Book 9th Edition</ref> However, classmate 4555 and 1420 visited the branch with an SLS railtour as far as [[Alveley Sidings]] on 19 September 1965. The Three members of the 4500 Class were rated Yellow C under the [[GWR Power class and Weight Classification | GWR system a further 11 of power and weight classification]] and 4MT under the British Railways system4575 class survive in preservation. 4566 was capable of pulling 8 coaches up Highley Bank from a standing start, but was generally restricted to 6 coaches or 200 tons due to its limited water capacity. It used the 'Standard 5' GWR boiler<ref>SVR News 184</ref> This resulted in its use in peak summer season usually being on services with shorter coaching sets such as dining trains, and also in periods spent on hire to other railways.

4566 was built in Swindon in 1924 to Lot No. 226 and entered service at Newton Abbot, and spent spending most of its working life based at sheds in Devon and Cornwall.<ref>[http://www.rail.co.uk/rail-news/2015/happy-birthday-dear-4566/ 'Happy birthday dear 4566', rail.co.uk, 19 June 2015] (Retrieved 3 January 2019)</ref> Post-War, the locomotive worked in the far south west, including allocations to St. Ives and Penzance shedswhere it was a common sight on the St. Erth to St. Ives and Gwinear Road to Helston branches. 4566 was notable for being the last steam locomotive overhauled at Newton Abbot works, completed on 15 July 1960, and being ceremonially driven out of the works by the chairman of the local urban district council (a mainline diesel driver).<refname=SVR15>[https:SVR News 15<//wwwref> Two weeks later on 28 July 1960, 4566 was photographed entering Gwinear Road with a 2-coach Helston branch train.facebook.com/permalink.php?story_fbid=1417780338248850&id=161421647218065 Didcot Railway Centre Facebook Page], retrieved 15 Jul 2016<ref>Photo reproduced in SVR News 46</ref>
