The [[GWR Power and Weight Classification]]were class E and axle load Blue respectively. During World War II some classes of locomotives were permitted to haul loads heavier than those specified in the working books for their power classification, distinguished by the white letter "X" painted above 2857's number plate.<ref>[https://www.svrwiki.com/GWR_Power_and_Weight_Classification Wikipedia]</ref> Post-war the class was rated 8F by BR.  

2857 is was built in 1918 at the GWR’s Swindon Works and delivered new to Salisbury GWR depot in May of that year.<ref>[http://www.brdatabase.info/locoqry.php?action=locodata&type=S&id=2857&loco=2857 BR Database]</ref> During a working life of 45 years it was based in many depots around the GWR Churchward 2800 Class (and later British Railways Western Region), including a brief spell at nearby Stourbridge shed in the early 1950s.

2857 was purchased from [[Barry Scrapyard | Woodham Bros scrap yard in scrapyard]] on 20th May 1974 by [[The 2857 Society|The 2857 Society]]for a cost of £5, and 250 plus £525 VAT; fund raising for the purchase was helped by a [[:Category:SVR fundraising lotteries|raffle organised by the SVRA Kidderminster branch]] which raised £1,950 nett.<ref>SVR News 33,34</ref> The locomotive was moved by rail from Barry to the Severn Valley Railway in convoy with Collett [[GWR Mogul 7325]], arriving on 20th 13th August 1975<ref>SVR News 37 p.2. and p.14.</ref><ref>SVR Stock Book Ninth Edition</ref> (the 2857 Preservation Society web site states 20 August).<ref>[http://www.2857.org.uk/2857_2-preservation.html 2857 Society web site 2]</ref> They were respectively the 69th and 70th locomotives to leave Barry.<ref>The Barry Story, Beckett & Hardingham (2010)</ref> ===Restoration and first steaming===Restoration began at Bewdley in January 1976 and was carried out in the open air. A major setback was the discovery of a cracked cylinder casting. Although attempts at welding this failed, the locomotive was first steamed in preservation on 9th September 1979, minus cladding. A replacement cylinder block was acquired, having been found during the demolition of the Briton Ferry Steelworks in South Wales. The locomotive was steamed intermittently through 1980 but without entering regularly in service. Mileage recorded during the period was as follows:{| class="wikitable"! <b>Year</b> !! style="text-align:right;" | <b>Mileage</b> |-| 1979 || style="text-align:right;" | 20|-| 1980 || style="text-align:right;" | 195|-| <b>Total</b> || style="text-align:right;" | 215|}===Continued restoration and first full boiler ticket===At the end of 1980 the SVR announced that preserved boilers on the railway needed to be brought up to 1980’s BR standards. The owning group therefore resumed the restoration, with the boiler being overhauled by the SVR as a contract job and the opportunity being taken to fit the replacement cylinder block among many other tasks. In spring 1984 a [[:Category:SVR fundraising lotteries|raffle organised by the SVRA Wolverhampton Branch]] was held to raise funds to help complete the restoration.<ref>SVR News 71, 74</ref> <div id="MainLine"></div>2857 was steamed again on 18th August 1985 and after a week of running in was able to make her only appearance on the main line hauling a demonstration freight train as part of the GW 150 celebrations of that year (as a heavy freight locomotive, 2857 was not considered suitable for main line passenger rail tours):{| class="wikitable"!Date!!Tour name !!

In December of that year water was discovered in both pistons, resulting in a period out of service for an episode of repairs.

After Following these troubles, 2857 became a reliable performer, recording the highest annual mileage of any steam locomotive on the SVR in each of the years 2013 to 2015. Mileage since 2010 is recorded on the [[Severn Valley Railway Timeline 2010-2019#Locomotives used | 2010-2019 Timeline page]]. However it became apparent in 2016 that as the locomotive approached its 100th anniversary, significant work would soon be required including relining the cylinders, replacing valves and pistons and attending to a bent piston rod. The locomotive was therefore withdrawn for an intermediate overhaulin September 2017, 2857 with a complete boiler re-entered tube being carried out at the same time.<ref>SVR News 201</ref> The locomotive returned to service on 16 May 2018<ref>[https://twitter.com/svrofficialsite/status/996798365215219713 SVR Social Media]</ref>, 100 years to the month since first entering service. On 18 September 2018 the locomotive passed 100,000 miles in preservation, carrying both a headboard "Still gong strong, 100,000 miles" and a "100" headcode.<ref>[https://twitter.com/svrofficialsite/status/1042674319820775426 SVR social media]</ref> The 100 headcode remained in July 2011use during the [[Autumn Steam Gala]] which began on 24 September.<ref>SVRLive</ref> It reappeared on 11 November for the centenary of Remembrance Day.
