No. D4100 was constructed at Horwich Works and entered BR service in September 1961 at Ashford. After moving to various locations, it was fitted with air brakes in 1968 before moving to Selhurst in July 1970. It became No. 09012 under the TOPS numbering scheme in January 1974. The locomotive was named 'Dick Hardy' in honour of Richard 'Dick' Hardy who was a Divisional Manager with BR and oversaw various railway changes.
After retiring in 1982, Richard became an author and wrote about railway heritage. The locomotive was withdrawn from service on 31st July 2010 and saved for preservation. In 2013, the locomotive arrived at the SVR under No. 09012 in a Departmental Grey livery. The Class 09 locomotive was overhauled and had its 'Dick Hardy' nameplates refitted in 2014. A BR Green livery was applied to the locomotive in 2015. D4100 is normally based at Kidderminster and operates as a shunter.
