1). The British Rail Class 15 diesel locomotives, also known as the BTH Type 1, were designed by British Thomson-Houston, and built by the Yorkshire Engine Company and the Clayton Equipment Company, between 1957 and 1961. They were numbered D8200-D8243. Class 15s were generally used on freight and infrastructure operations, and haulage of passenger trains was limited to replacement as a result of failure. 60 mph (97 km/h) 800 hp 2).The British Rail Class 16 also known as the North British Type 1 was a type of diesel locomotive designed and manufactured by the North British Locomotive Company. A total of ten were produced, these being numbered D8400-D8409. Upon their completion, all ten Class 16 locomotives (numbered D8400–D8409) were delivered to Devons Road depot, Bow, North-east London on the London Midland Region of British Railways between May and September 1958. 60 mph (97 km/h) 800 hp 3). The British Rail Class 17 (also known as the Clayton Type 1) was a class of 117 Bo-Bo diesel-electric locomotives built 1962–1965 by Clayton Equipment Company and their sub-contractor Beyer, Peacock & Co., on behalf of British Railways (BR). The Clayton examples were delivered to the Scottish Region depots at Polmadie (D8500–D8553) and Haymarket (D8554–D8567), although some later migrated to Kingmoor (Carlisle) on the London Midland Region. The Beyer Peacock locomotives were new to the North Eastern Region at Thornaby (D8588–D8591) and Gateshead (D8592–D8603) and to the Eastern Region at Tinsley and Barrow Hill. 60 mph (97 km/h) 450 hp × 2 = 900 hp 4). The British Rail Class 21 was a type of Type 2 diesel-electric locomotive built by the North British Locomotive Company in Glasgow for British Rail in 1958–1960. The first 38 locomotives entered service in 1958-59 from the Eastern Region depots at Stratford, Hornsey and Ipswich engine shed on commuter services into London, where they were evaluated against rival designs from English Electric, British Railways, Birmingham RC&W and Brush. The final 20 locomotives had uprated 1,100 hp (820 kW) engines and were delivered to Kittybrewster depot on the Scottish Region. 75 mph (121 km/h) 1000 or 1100 hp 5). The British Rail Class 22 or "Baby Warship" was a class of diesel-hydraulic locomotives designed for the Western Region of British Railways and built by the North British Locomotive Company. They were very similar in appearance to the Class 21 diesel-electrics. D6300 was introduced to traffic in 1959 and deliveries continued until 1962. The Class 22s were allocated to Bristol Bath Road, Laira Plymouth, Newton Abbot and Old Oak Common. The majority of the class always operated in the West of England, on a range of local passenger and freight work, with smaller numbers of the later units operating on local work in the Bristol area and around London Paddington (notably moving empty carriages between the main station and Old Oak Common yard). 75 mph (121 km/h) 1000 - 1100 hp. 6). The British Rail Class 28 (Metro-Vick Type 2) diesel-electric locomotives, known variously as 'Metrovicks', 'Crossleys'[1] or 'Co-Bos', were built under the Pilot Scheme for diesel locomotives as part of the British Railways 1955 Modernisation Plan. All twenty Metrovicks were initially allocated to the Midland Division of BR's London Midland Region, where they were often used in pairs on the overnight London–Glasgow "Condor" express freight service. After the 1961 refurbishment they were all transferred to the Barrow-in-Furness 12E depot. They were withdrawn after only eleven years at work and in service. The allocation of all twenty locomotives in October 1967 was Carlisle Upperby. 75 mph (121 km/h) 1200 hp 7). The British Rail Class 29 were a class of 20 diesel-electric Bo-Bo locomotives produced by the re-engining of the NBL Type 2 units (BR Class 21). The units were designed for both passenger and freight trains. 80 mph (130 km/h) 1,350 hp 8). The British Rail Class 41 diesel-hydraulic locomotives were built by the North British Locomotive Company in Glasgow during 1957 and 1958. Although they were withdrawn before TOPS was introduced, British Rail classified them as Class 41. Entering service between January 1958 and January 1959, the class initially worked on the London-Plymouth-Penzance route of the Western Region. 90 mph (145 km/h) (2x) 1000 = 2000 hp List of British Rail modern traction locomotive classes - Wikipedia
