The BR Class 22 is a type of B-B diesel locomotive designed for the Western Region of BR and built by NBL. Nicknamed the 'Baby Warship' due to their similarity to the D6xx (Class 41, also a NBL product). Fifty seven of these locomotives were built between 1959 and 1962 and operated in the West of England hauling both passengers and freight. The class was eventually displaced by the more powerful and reliable Hymeks and Warships, exacerbated by the bankruptcy of NBL in 1962 and the consequential lack of spares. By 1971 all had been decommissioned and none survived into preservation. Dapols’ OO model was produced after years of extensive study of plans and drawings and by collaborative work with various locomotive experts.
