Stanier Class 5 4-6-0 5231 (British Railways no. 45231) is a preserved British steam locomotive. In preservation, it has carried the names 3rd (Volunteer) Battalion The Worcestershire and Sherwood Foresters Regiment and The Sherwood Forester, though it never carried either of these in service. Service 5231 was built by Armstrong-Whitworth in 1936 for the London, Midland and Scottish Railway. It spent most of its early career at Patricroft shed, working mainly to North Wales and Leeds. After nationalisation in 1948, it was renumbered 45231 by British Railways. 45231 was transferred to Northampton in October 1954, but was only officially there for a month — such allocation changes were often only carried out on paper — and then transferred to Aston, where it remained for nine years. 45231 was officially transferred to Rugby in February 1963, but was moved a short time later (July) to Chester. It stayed at Chester until closure of Chester shed in April 1967 when 45231 was then transferred to Speke Junction and finally Carnforth, where 45231 lasted until the last day of steam on BR in August 1968. It was sold by BR directly into preservation and was restored at Carnforth to LMS livery. This locomotive was one of a total of 842 with four of its class having the following names: 45154 Lanarkshire Yeomanry, 45156 Ayrshire Yeomanry, 45157 The Glasgow Highlander, and 45158 The Glasgow Yeomanry. Preservation After being initially preserved at Carnforth, 5231 became associated with the preserved Great Central Railway (GCR) in Leicestershire. In 1973, it hauled the official opening train between Loughborough and Quorn. Never having carried a name in BR service, the locomotive was nonetheless named 3rd (Volunteer) Battalion The Worcestershire and Sherwood Foresters Regiment at Quorn on 9 May 1976. It was taken out of service the following year for an overhaul. 5231 was overhauled in Cornwall, and was complete in 1988, when it returned to the GCR. It was then moved to the Nene Valley Railway from 1989 until 1993, when it returned to the GCR for the filming of Shadowlands. 5231 was sold to the GCR in late 1996, who repainted it in BR lined black in 1997. It also acquired a new set of nameplates, this time more simply The Sherwood Forester. A very similar name was carried by LMS Royal Scot Class (4)6112 Sherwood Forester. 45231 emerged from an overhaul in 2005 and shortly after it
