 45110 was initially saved for preservation by "[[List of preservation groups#Preservation groups formerly associated with the SVR|The Stanier Black 5 Locomotive Preservation Society]]", mainly through fund raising efforts of its President Mr David Porter, Principal of the “Flairavia Flying Club” at Biggin Hill Civil Airport. After a temporary move On 8 January 1969 the locomotive was hauled ‘dead’ from Lostock Hall to Clapham Sidings in January 1969, . Three days later 45110 found was moved again to a temporary home at the privately rented former BR Ashford shed. During an There it was worked on by members of the Flying Club and steamed on several open day theredays, 45110 during one of which it first carried temporary name plates bearing the name “R.A.F. Biggin Hill”. <ref name=SVR18>SVR News 18, 19</ref>

It became clear that a new home for the locomotive at a heritage railway was needed and Mr Porter considered the SVR to be the most suitable. 45110 arrived left Ashford on 17 August 1970, being hauled dead to Bescot on 19 August. There the motion was reattached and a fire lit, so when the SVR locomotive arrived at Bewdley on 20 August 1970 in working order and , it continued to Bridgnorth under its own steam. Minimum work was required before 45110 entered service on Sunday 20 September 1970. <ref name=SVR18/> A naming ceremony was held on 12 September 1971, at which the locomotive was formally named “R.A.F. Biggin Hill”. David Porter, a SVR Director and owner of [[417 Invicta]], sold it to the <ref>SVR in 1974.News 21</ref>

David Porter (who was also associated with [[417 Invicta]]) became a Director of SVR(H) when it was first established in late 1972.<ref>SVR News 26</ref> On 11 August 1973, with his agreement, 45110 took part in a Derby Litchurch Lane Carriage Works "Open Day". The locomotive travelled there and back in steam with [[LMS 24617 Corridor Composite]], [[LMS 26986 Brake Third Corridor]] and [[LMS 2886 Six-wheel Passenger Brake (later 32919)|Stove R 32919]], thereby becoming the first Severn Valley locomotive and rolling stock to work unassisted on the BR network in preservation.<ref>SVR News 29</ref> The move also resulted in the locomotive leaving facing south and returning facing north, thus becoming only the second locomotive on the SVR to work facing in each direction.<ref>SVR News 115, “North and South before the Turntable”, Quentin Haigh</ref><ref group="note">[[46443]] arrived facing south but returned from an open day at Tyseley in September 1969 facing north, the only locomotive to be turned before the SVR opened. </ref> During 1975 45110 was one of the locomotives used in the filming of [[The Seven-Per-Cent Solution]]. Shortly before that time 45110 was put up for sale, and although it was not SVR policy to own locomotives, the joint Boards decided that it should stay on the SVR if possible, so an exception was made and the purchase of 45110 was successfully negotiated.<ref>SVR News 37, p.3.</ref> The terms agreed were £19,000 with a 25% down payment and the balance payable over three years, subject to signature of the film contract. The decision caused great upset amongst members at the time, with threats of petitions being raised and membership cards torn up.<ref>SVR News 37, “The Unpopular Decision”, David C Williams (Editor) p.35.</ref> The first period of service ended 10 years later in 1980 after recording 21,185 miles in use. Following overhaul, a second period of service began in 1998. This lasted until late 2008, including a 6-month boiler ticket extension which enabled the locomotive to celebrate the 40th anniversary of the end of BR main line steam. During this period a number of main line appearances were made as follows:
