It was originally built as Ogmore Castle in May 1939 at Swindon Works, the engine being one of the many popular GWR Castle Class. Its first shed allocation was Old Oak Common.

RenamingPrior to 5080's transfer to Cardiff Canton from Swindon, the engine was renamed Defiant in January 1941, commemorating one of the many types of aircraft which had taken part in the Battle of Britain. The engines original name Ogmore Castle was also used on an earlier member of the class as well as being later used by two sister engines, the name was originally allocated to 5056 before being renamed Earl of Powis in Sept 1937. Following 5080's renaming the name was transferred to 7007 (later re-named Great Western in Jan 1948) & 7035. British RailwaysAfter the arrival of the Britannia class Pacifics on the Western Region of British Railways, in 1959 it was moved to Carmarthen, staying there until its final move to Llanelli in May 1961. Withdrawal and PreservationIt was withdrawn in April 1963, and acquired by Woodham Brothers scrapyard in Barry, Vale of Glamorgan, South Wales in October 1963.[2] It was sold to the Standard Gauge Steam Trust (since renamed Tyseley Locomotive Works), initially as spare parts for 7029 Clun Castle, and left as the 62nd departure from Barry in August 1974. Its restoration was completed in June 1988, and it ran for a number of years. After its boiler certificate expired, it was sent to be displayed at the Buckinghamshire Railway Centre, where it remained until May 2017 when it was returned to Tyseley. Defiant is at present stored at Tyseley Loco Works, but makes appearances at Tyseley's open weekends as a static exhibit, and a group called "The Defiant Club" are raising money to fund an overhaul of 5080 Defiant for a return to service on the mainline to work excursion trains.[3][4] GalleryBelow are a set of photos showing 5080 during its career with British Railways alongside its time at Barry Island and in preservation.
