'''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> The However, classmate 4555 and 1420 visited the branch with an SLS railtour as far as [[Alveley Sidings]] on 19 September 1965. Three members of the 4500 class and a further 11 of the 4575 class survive in preservation. 4566 was capable of pulling 8 coaches up Highley Bank from a standing start, but was rated 4MT by British Railwaysgenerally restricted to 6 coaches or 200 tons due to its limited water capacity.<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, 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>

It was officially withdrawn from BR service at Plymouth Laira shed there in April 1962 having achieved 967,914 miles in preservationservice, but was stored for a further few months before being sold for scrap and arriving at [[Barry Scrapyard | Barry]] in August of that year.<ref name = "BarryStory">The Barry Story,Beckett & Hardingham (2010)</ref><ref name = "SB9"/><ref>[http://www.greatwestern.org.uk/262_4500det.htm The Great Western Archive] retrieved (Retrieved 27 January 2015,</ref> arriving at [[Barry Scrapyard | Barry]] in August of that year.<ref name = "BarryStory">The Barry Story, Beckett & Hardingham (2010)</ref>

===Restoration and first boiler ticket===4566 was selected by two S.V.R. members, David Rouse and Bob Sim, as the most suitable small prairie for preservation out of several examples of the type at Barry, appearing in generally good order apart from missing footplate fittings.<ref name=SVR15/> It was only the 8th locomotive to leave Barry and the first from there destined for the SVR.<ref name = "BarryStory" /> She  4566 arrived at Bewdley by rail, diesel hauled, on 25 August 1970, with restoration beginning there shortly afterwards.<Ref> SVR News 18</ref> Restoration By the end of 1972 the boiler had been re-tubed and passed a hydraulic test. The complete bunker unit had been sent away to a railway engineering factory and returned with new platework.

The tanks and cab roof were refitted, and new ashpan built and fitted. Two new spectacle windows were remade and fitted in the front of the cab to replace those originally installed when built but later blanked out by BR.<ref>SVR News 34</ref>  The restoration was completed in time for the locomotive to enter service in on 5 July 1975, the inaugural trip from Bewdley to Bridgnorth being an evening special train double headed with [[46521]] to mark the 10th anniversary of the formation of the SVR.<ref name = "SB9">SVR News 36</ref> The locomotive initially proved very reliable, recording 3,310 miles in just 5 months including 1,410 miles in 22 days during August.<ref>SVR News 38</ref> Over the following winter the locomotive was fitted with steam heating.<ref>SVR News 39</ref> The following year 4566 was used in filming of Walt Disney's live action film [[Candleshoe]], <ref>SVR News 42</ref> with the locomotive also appearing in the 1977 TV movie [[Silver Blaze]].
