Initially 70000 was stored as a candidate for the National Railway Museum’s National Collection. However, due to her prototype design and construction differences, the NRM selected 70013 Oliver Cromwell, instead. Britannia was eventually bought by Britannia Locomotive Company Ltd.
Britannia arrived at the SVR in [[Severn Valley Railway Timeline 1970-1979#1971 | April 1971]] for restoration to be completed. This was achieved in [[Severn Valley Railway Timeline 1970-1979#1978 | May 1978]], 12 years, after the locomotive had last steamed. 70000 was renamed ‘Britannia’ at a ceremony on 20 May 1978 by Mr R A Riddles, the locomotive’s designer.
Britannia left the SVR in spring 1989. After a period of ownership by Pete Waterman, the locomotive was bought by Jeremy Hosking and was transferred to the Royal Scot Locomotive and General Trust <ref>[http://www.royalscot.org.uk/ Royal Scot Locomotive and General Trust web page] Retrieved 25 February 2015.</ref>.
