D9526 is one of 56 locos in this class built by British Railways at Swindon Works between 1964 and 1965. Intended to pull freight, they were made redundant almost immediately by the closure of many secondary lines in the late 1960’s. Almost the entire fleet was sold for use in industry, with 23 going to Stewarts and Lloyds iron ore mines in Corby and 19 going to the National Coal Board’s North East Area.

D9526 was sold to Blue Circle Industries, a cement manufacturer in Westbury, where it worked until suffering serious engine problems in 1977. It was donated to the DEPG by Blue Circle and moved to Williton in 1980. After repairs and restoration work, D9526 made its preservation debut in 1984, working on the West Somerset Railway for a further ten years. At the end of the 1994 season, it was taken out of service with turbocharger and oil pressure problems. It re-entered service again in April 2003.

It visited the South Devon Railway in 2018 for their Diesel Gala.

D9526 was on loan to the Kent & East Sussex Railway from July 2021 to January 2023.
