Similar to that of 60163 Tornado which was built as no original members of the LNER Peppercorn A1 class were preserved no original B17's were preserved. 61673 is being built at the Llangollen Railway by the B17 Steam Locomotive Trust and the plan is once the engine is completed 61673 will operate on heritage railways as well as be certified for main line use out on the national network hauling railtours across the UK. BackgroundThe original B17's were built from 1928 up-to 1937 with the construction of the seventy three engines being split between: North British Locomotive Company, Darlington Works & Robert Stephenson and Company. By 1960, withdrawal of the class was well underway with only seventeen remaining in service at the start of the year, the final original B17 to be withdrawn was 61668 Bradford City which was withdrawn in August 1968 and would be cut up not that long after withdrawal. The highest working life for a B17 being 31 years (61608 Gunton) & the lowest for the class being 21 years (61667 Bradford). It was announced in Steam Railway magazine issue 349, on 1 May 2008 that a group planned to launch a project to built two B17's (one being a replica of 61662 "Manchester United" while the other would be numbered 61673 and given the name "Spirit of Sandringham"). 61673's construction is now being undertook in Llangollen by the B17 Steam Locomotive Project while the replica engine is now being built at a private site by the 61662 appeal.[1] Name, number and liveriesA small number of B17's wore the LNER's famous Apple green livery as well as NE unlined and lined black, and for a brief period one even emerged in LNER Apple Green with British Railways lettering on the tender. However B17's were mainly seen in BR green with either the early emblem (pre 1956) or the later crest (post 1956). It's not yet known which livery the completed engine will wear first and it's expected that a decision will be reached near to when the engine is completed. Project milestones
