Built by English Electric between 1958 and 1962, and eventually numbering 200, they were for a time the pride of the British Rail early diesel fleet. Despite their initial success, by the time the last examples were entering service they were already being replaced on some top-link duties by more powerful locomotives. As they were slowly relegated from express passenger uses, the type found work on secondary passenger and freight services where they worked for many years, the final locomotives being retired from regular service in 1985. The origins of the Class 40 fleet lay in the prototype diesel locomotives (Types D16/1 ordered by the London, Midland and Scottish Railway and British Railways and D16/2 ordered by British Railways between 1947 and 1954) and most notably with the Southern Region locomotive No. 10203, which was powered by English Electric's 16SVT MkII engine developing 2,000 bhp (1,460 kW). The bogie design and power train of 10203 was used almost unchanged on the first ten production Class 40s. Following the mixed success of the prototypes, another 190 locomotives were ordered by British Railways, and were numbered from D210 to D399. All were built at Vulcan Foundry, except a batch of twenty (Nos. D305–D324) which were built at Robert Stephenson and Hawthorns factory in Darlington. All the locomotives were painted in the British Railways diesel green livery, and the final locomotive, D399, was delivered in September 1962. Batches of the class were built with significant design differences, due to changes in railway working practices. The first 125 locomotives, Nos. D200–D324, were built with steam-age 'disc' headcode markers, which BR used to identify services. Later, it was decided that locomotives should display the four character train reporting number (or headcode) of the service they were hauling, and Nos. D325–D344 were built with 'split' headcode boxes, which displayed two characters either side of the locomotive's central gangway doors. Another policy decision led to the discontinuing of the gangway doors (which enabled train crew to move between two or three locomotives in multiple). The remaining locomotives, Nos. D345–D399, carried a central four-character headcode box. In 1965, seven of the first batch of locomotives, Nos. D260–D266, which were based in Scotland, were converted to the central headcode design. From 1973, locomotives were renumbered to suit the TOPS computer operating system, and became known as 'Class 40'. Locomotives D201 to D399 were renumbered in sequence into the range 40 001 to 40 199. The first built locomotive, D200, was renumbered 40 122, which was vacant due to the scrapping of D322 as the result of accident damage.
