1450 spent her early life in preservation at the Dart Valley Railway (now the South Devon Railway).<ref>[http://www.southdevonrailway.co.uk/gone-not-forgotten/1450 SDR web site], retrieved 25 January 2015.</ref> She was purchased in 2001-02 by her present owner [[Pull Push Limited]], of whom Mike Little is sole director, and re-located to the Dean Forest Railway.
1450 arrived at the SVR from the DFR in March 2014, initially on hire for the year. Subsequently 1450 has been listed as part of the home fleet. Although not powerful enough to haul service trains on her own 1450 did so in 2014, double heading with [] to provide the required power, due to a number of ongoing locomotive repairs leaving the SVR unexpectedly short on engines. The locomotive
is regularly used on Footplate Experience duties, as well as appearing on charters and at galas on the SVR and elsewhere. She is often paired with the owner's autocoaches [[GWR 178 Autotrailer Third | 178]] and [[GWR 238 Autotrailer Third | 238]] which are also resident on the SVR.
Whilst 1450 was winterised at [[Bridgnorth MPD]] over 2017-18 she returned to GWR livery, at the owner's request, for the remainder of its
current boiler ticket.<ref>[https://twitter.com/svrofficialsite/status/947815226602348545 SVR Twitter 1 January 2018]</ref>
During 2019 the locomotive visited the Didcot Railway Centre from the end of April until early September.<ref>[https://www.didcotrailwaycentre.org.uk Didcot Railway Centre website]</ref> [[GWR Large Prairie 4144]] was on loan to the SVR from Didcot for summer 2019, an arrangement which suited both parties.
At the end of 2019, 1450 had recorded a total of 13,503 miles in preservation on the SVR. The reported total may include mileage on hire to other railways<ref>SVR News 210, SVR-based Steam Locomotive Mileage 2017-2019, Duncan Ballard</ref>
It was withdrawn from traffic in December 2020 at the expiry of its boiler certificate.
On 15 July 1973 1450 with GWR autocoaches 190 and 231 ran on the main line between Marlow and Bourne end during the "Marlow Donkey Centenary Day", an event held to commemorate the centenary of the Marlow branch. 1450 was a late replacement for Didcot's classmate 1466.<ref>[http://www.mdrs.org.uk/wycmaidmarlow.htm#1970s Photos on Marlow & District Railway Society website] (retrieved 26 November 2020)</ref><ref>[https://www.mmpa.org.uk/gallery/gallery29/p01.jpeg Timetable on MMPA.org.uk](retrieved 26 November 2020)</ref>
In 1988 1450 ran three days of 'The Dawlish Donkey' mainline trips, from Exeter to Newton Abbot and return.<ref>[http://www.uksteam.info/tours/trs98.htm uksteam website] (Retrieved 11 July 2019)</ref>
. In subsequent years the operation was expanded, with larger locomotives hauling longer trains over longer routes.
