The British Industries Fair was an important exhibition centre in Birmingham, England. The large complex of buildings was built in 1920 and was situated between Castle Bromwich Aerodrome and the railway line. For two weeks every year it was the most visited attraction in the country. In 1933, the first diesel locomotive arrived for display at the BIF. The site was sold in 1960, along with that of the airfield. The buildings and the sites were cleared for the construction of the Castle Vale housing estate. The BIF was replaced by the National Exhibition Centre.
