'''50026 Indomitable ''' is a ''BR Class 50 diesel locomotive '' owned and operated by Paul Spracklen. ==BR Class 50==Fifty English Electric Type 4 (later BR Class 50) diesel locomotives were built by English Electric at their Vulcan Foundry Works plant It spent several months on hire to the SVR in Newton-le-Willows between 1967 2014 and 1968. When built they were numbered in has also attended the D4xx series. They later became BR’s Class 50, being allocated TOPS numbers in railway for appearances at [[Diesel galas]] and maintenance at the 50xxx series[[Diesel Depot]]. The class was nicknamed “Hoovers” because A brief history of the distinctive sound of the inertial air-filters with which the locomotives were originally fitted. Initially the locomotives were used to haul express passenger trains on the West Coast Main Line (WCML) between Crewe and Scotland; that section not then being electrified. This often entailed ‘Multiple Working’, with two locomotives class can be found under control of a single driver. By 1974 the northern WCML had been electrified, and the [[BR Class 50 fleet was being transferred to BR’s Western Region to work main line passenger services out of London Paddington. The Class 50’s did not originally carry names, but in the late 1970s BR agreed to their being named after Royal Navy vessels with notable records in the First and Second World Wars.  Withdrawal of the class began in the early 1990s50044 Exeter|50044 Exeter]].

D426 entered service in July 1968 and was later renumbered 50026 under [[TOPS codes|TOPS]] renumbering. In March 1978, 50026 was named Indomitable after the Royal Navy's modified Illustrious-class aircraft carrierwhich was scrapped in 1955.

50026 was 50026’s survival is somewhat remarkable as the locomotive is the only one of several locomotives sent the Class 50s surviving today that managed to escape from the scrapyard. It languished in the yard of C F Booth's scrap yard in Rotherham , one of several locomotives sent there in 1992. These locomotives were part of an ultimately unsuccessful bid project by 'Operation Collingwood'. The current owners owner, Paul Spracklen, purchased 50026 the locomotive together with missing parts salvaged from the other project locomotives that were missing from 50026went for scrap.<ref>[https://en.wikipedia.org/wiki/British_Rail_Class_50#Preservation Operation Collingwood in Wikipedia] (Retrieved 30 September 2018}</ref>
