Large prairie tanks were a common sight on the GWR, with more than 300 built between 1903 and 1949 to the same basic design. The locomotives were designed to haul semi-fast and suburban passenger services to tight schedules, and were also used on medium distance freight services.

5164 is a GWR The 5101 Class was an updated version by CB Collett 5101 class 2-6-2T 'Large Prairieof Churchward's 1903 3100/5100 Class. These Built from 1929 to 1949, these medium-sized tank engines were used all over the GWR network for suburban and local passenger and local freight services. British Railways Their increased axle loading of 17 tons 12 cwt was the maximum permitted for [[GWR Power and Weight Classification | 'Blue' route availability]], while their [[GWR Power and Weight Classification|power class]] was rated D (GWR) and 4MT (BR).  A total of 140 were produced; after available numbers in the 51xx range were exhausted, later examples were numbered in the 41xx range. The prevalence of the Large Prairie also resulted in examples numbered 61xx, 31xx and 81xx.<ref>[http://www.greatwestern.org.uk/m_in_262.htm Great Western Archive]</ref>This followed GWR practice, where more than 100 locomotives of one class were built, of maintaining the second number in the series and re-using older sequences of numbers where necessary.  A number of the class 4MTwere allocated to the sheds at [[Worcester]], [[Kidderminster Shed|Kidderminster]], Stourbridge and [[Shrewsbury#Shrewsbury Shed|Shrewsbury]] from where they were [[Locomotives used on the Severn Valley Branch in commercial service|regularly used on the Severn Valley Branch]] on both freight and passenger services after the 1950s.

By summer 1971, with a 5700 Pannier Tank and 4500 'Small Prairie' already secured for the SVR, purchase of a 'Large Prairie' was seen as the next logical step. A fund was established, organised by Mr. R.E. 'Bob' Sim, and No. 5164 was chosen by the 5164 Fund as the best of the 10 large prairies 'Large Prairies' at Barry. It was reserved for purchase 'with the usual help from Mr Woodham' while an appeal for fund raising took place.<ref name=SVR20/> <gallery mode=packed heights=200px style="text-align:left">S2445_5164_Barry_David_Cooke.jpg|5164 at Barry, and purchased (David Cooke)</gallery> Purchase was successfully completed at a cost of £2,250.<ref name="5164org" /> The locomotive was officially the 30th to leave Barry,<ref>The Barry Story, Beckett & Hardingham, 2010</ref>, arriving on the SVR on 6 January 1973 in the company of [[GWR 4930 Hagley Hall]] and [[GWR 7819 Hinton Manor]]. The initial owners were [[The 5164 Preservation Group]]. 

Restoration took place at Bewdley, with a team led by Pete Simpson. By September 1974 the engine had been completely stripped down. The tyres all needed reprofiling which, if done, would have left sufficient material for one further turning. However with a loose tyre having brought about the locomotive's withdrawal from service, the decision was completed taken to replace all the tyres, the work being carried out by the BSC Railway Materials Division at Rotherham. The tanks and bunker were overhauled by Wagon Repairs Ltd of Stoke-on-Trent. The boiler was refitted on 3 May 1976 as part of the [[Severn Valley Railway Timeline 1970-1979#1976|'150 ton big lift']] which saw the lifting of 5 boilers and 2 frames in a single day.<ref>SVR News 40</ref> 5164 was not steamed until 20 October 1979 when , by which time the entire restoration was effectively complete, as by the following week the locomotive had moved to Bridgnorth ready for use on that December's Bridgnorth to [[Hampton Loade]] [[Christmas services]].<ref group="note">The [https://www.erlestokemanorfund.co.uk/new-year-2024-news-update/ EMF's 2024 New Year update] included Peter Mudie's recollections of 5164’s original restoration and his photographs of its first steaming and test runs.</ref> It formally entered service in December, performing faultlessly and recording the highest mileage of the three locomotives used.<ref>SVR News 54, 55</ref>  5164 was taken out of service in late summer 1980 for some 'finishing touches' and a full repaint.<ref>SVR News 56</ref> Retuning to service in 1981, the locomotive suffered some frost damage during the first timefollowing winter<ref>SVR News 63</ref> but continued in service until being withdrawn due to tube failures in July 1984. <ref>SVR News 73</ref> Mileage recorded during the first boiler ticket was as follows:<ref name ="SVR152" >SVR News 152 ppp.24-25</ref>

By the end of 1999 some component refurbishment had been carried out, hampered by the lack of machine shop facilities at Bewdley. By summer 2001 5164 was deemed necessary including 'next in line to be put through the shops' at Bridgnorth. In summer 2002 work on the boiler crown stays was under way, with the [[The Erlestoke Manor Fund|Erlestoke Manor Fund]] team assisting the boilersmiths in de-tubing and de-staying. The mechanical overhaul was also starting and new side stays tanks were being fabricated.<ref>SVR News 136, 140, 142</ref>. The boiler was steamed in mid-2003, and a full mechanical repairnew hopper ash-pan wad being fabricated to complement the new rocking grate already made by Pete Simpson at Bewdley.
