Locomotive numbering

Locomotives frequently carried more than one number during their working life. Renumbering came about through company mergers, in particular the Grouping of 1923, and Nationalisation in 1947, from which only the GWRGreat Western Railway emerged relatively unaffected, whilst SRSouthern Railway numbers were generally incremented by 30,000, LMSLondon Midland & Scottish Railway by 40,000 and LNERLondon & North Eastern Railway by 60,000. Companies also renumbered for other operational reasons, as happened to GWR 1450.

Many locomotives have also carried more than one number in preservation. For consistency all locomotives are listed according to the last number they carried, usually that used by BRBritish Rail or British Railways following nationalisation. Locomotives that were owned by a main line company and were sold for use in industry are listed under their last main line number. Locomotives that ran under a different number while at the SVRSevern Valley Railway were:
