British Locomotive Workshops

British steam locomotives were built in a remarkable network of company-owned workshops, ranging from the great mainline factories at Crewe, Swindon, Doncaster, Derby and Eastleigh, each turning out hundreds of new engines a year at peak, to specialist works supplying export and industrial customers, and the smaller railway shops that maintained an entire region's fleet. This section catalogues 58 of the most significant.

Each entry covers the works's location, founding date, principal output, the railway company or private builder it served, key locomotives built there, and either the date of closure or its current role. Many of the great works closed during the contraction of British Rail; some sites are now industrial estates or housing, while a handful, including the National Railway Museum's Locomotion site at Shildon, survive as preserved heritage centres.
