The British Rail Class D3/6 were diesel shunters designed in 1934/5 by English Electric for the London, Midland and Scottish Railway. (LMS)
Between 1931 and 1934, the LMS ordered nine prototype 0-6-0 diesel shunters of different designs. The last of these was based on the English Electric 6K of 300 horsepower (220 kW) diesel engine, with a long bonnet ("nose"), 0-6-0 wheel arrangement, EE 6K prime mover and two axle-hung traction motors. It was built by Hawthorne Leslie to English Electric design. [1] Similar prototypes were later built for the Southern Railway (SR1-3), Great Western Railway (GWR2), and London and North Eastern Railway (8000-8004) and this configuration was repeated in most subsequent large diesel shunters built in Britain, such as the British Rail Class 11 and even more numerous British Rail Class 08 that entered service after World War II.
After modification and uprating to 350 horsepower (260 kW), the prototype was taken into LMS stock in 1936 and numbered 7079, (later British Railways number 12002. It was withdrawn and scrapped in 1956. [2]
Ten further locomotives of the same design, with minor alterations and uprated to 350 horsepower (260 kW), were built in 1935 and taken into LMSR stock in 1936. These were numbered 7069-7078 by the LMS. Three of these later became British Railways numbers 12000–12002 (previously 7074/76/79 respectively). They spent their working lives allocated to Crewe South Locomotive Depot.
The remainder of the class were sold to the British War Department in 1940 and were shipped to France during World War II. Of these, the first production locomotive, No. 7069, survived the war and was used in industrial service in France. It was later repatriated for preservation and is currently located and being restored at the Berkeley Vale Railway. [3]
The British Rail Class 04 is a 0-6-0 diesel-mechanical shunting locomotive class, built between 1952 and 1962 and was the basis for the later Class 03 built in the British Railways workshops.
The British Rail Class 09 is a class of 0-6-0 diesel locomotive designed primarily for shunting and short-distance freight trips along branch lines.
The British Rail Class 10 diesel locomotives are a variant of the standard Class 08 diesel-electric shunter with a Lister Blackstone diesel engine and General Electric Company plc (GEC) traction motors. The locomotives were built at the BR Works in Darlington and Doncaster over the period 1955–1962, and were withdrawn between February 1967 and June 1972.
The British Rail Class 11 was applied to a batch of diesel shunting locomotives built from April 1945 to December 1952, based on a similar earlier batch built by the London, Midland and Scottish Railway (LMS) between 1934 and 1936.
The British Rail Class 12 is a diesel locomotive built primarily for shunting duties around London.
The Córas Iompair Éireann 401 Class locomotives were built in 1957–1958 and designed for use on branch line traffic and shunting. They were fitted with a Maybach MD220 engine of 420 hp (310 kW), with diesel hydraulic transmission via a Mekydro KL64 transmission, and were of C wheel arrangement.
The Córas Iompair Éireann 421 Class was a railway locomotive, built by the CIÉ at Inchicore Works between 1962–1963 and designed for branch line traffic use and shunting.
The Córas Iompair Éireann 601 Class locomotives were built in 1956-1957, by Motorenfabrik Deutz at Cologne, Germany. They were 3 small shunting locomotives of B wheel arrangement and were fitted with a Deutz V8 F8L 614 engine of 130 hp, with Voith hydraulic transmission and chain final drive. They weighed only 18 tons and had a maximum speed of 32 kilometres per hour (20 mph). These locomotives were never fitted with train brakes, so had limited usefulness compared to their successors, the G611 class. The G601 locomotives were withdrawn from service between 1965 and 1972.
The CIE 501 Class locomotives were built in 1955 by Walker Brothers of Wigan for use on the narrow gauge lines on the West Clare section of the CIÉ. They were small diesel mechanical locomotives, with a 0-4-0+0-4-0 wheel arrangement. Controlled from a central cab, the locomotives had two Gardner engines of 224 hp (167 kW), one under each end casing, driving through a fluid coupling and Wilson gear box the inner axle of the opposite bogie, through a spiral-bevel-reverse and reduction gear box. Unusually the locomotives were driven from a seat mounted sideways to the direction of travel giving a clear field of vision both ways by a mere turn of the head.
The Córas Iompair Éireann 113 class locomotives were the first mainline diesel locomotives used in Ireland, being built in January 1950 and October 1951 by CIÉ at their Inchicore Works. They were fitted with Sulzer 6LDA28 engines of 915 hp (682 kW), with four Metropolitan-Vickers MV157 traction motors. They were of Bo-Bo wheel arrangement, weighed 80 tonnes and had a maximum speed of 90 km/h (56 mph). They were initially numbered 1100–1101 in the steam locomotive number series, but were subsequently renumbered B113–B114 in 1957.
The Córas Iompair Éireann 101 Class locomotives, numbered B101-B112, were built in 1956 by the Birmingham Railway Carriage and Wagon Company. They were fitted with Sulzer 6LDA28 engines of 960 hp (720 kW), with four Metropolitan-Vickers MV137 traction motors. They were of A1A-A1A wheel arrangement, weighed 75 tonnes and had a maximum speed of 120 km/h (75 mph).
The Córas Iompair Éireann 181 Class locomotives were built in 1966 by General Motors Electro-Motive Division (EMD) and numbered B181 to B192.
D0226 and D0227 were two prototype diesel shunting locomotives built in 1956 by English Electric at its Vulcan Foundry in Newton-le-Willows to demonstrate its wares to British Railways. They originally carried numbers D226 and D227, their Vulcan Foundry works numbers, but these were amended in August 1959 to avoid clashing with the numbers of new Class 40 locomotives.
The London, Midland and Scottish Railway (LMS) pioneered the use of diesel shunting locomotives in Great Britain. The variety of experimental and production diesel shunters produced by the LMS is summarised below.
LMS diesel shunter 7050 is an experimental 0-4-0 diesel-mechanical shunting locomotive, introduced by the London Midland and Scottish Railway (LMS) in 1934 and which remained in service with that railway for six years. It was later acquired for military use and is now preserved at the National Railway Museum.
British Railways Class D16/2 was a class of prototype diesel locomotives built by British Railways at Ashford Works and introduced in 1950–1951, with a third example being introduced in 1954. They had been designed by Oliver Bulleid for the Southern Railway and were authorised in February 1947 but did not appear until after nationalisation. The diesel engine and transmission were supplied by English Electric, but the Bulleid influence was obvious. The box-like body style closely resembled Bulleid's electric locomotives and was quite different from the usual English Electric style, typified by British Rail Class D16/1 which in turn was strongly influenced by contemporary American design.
British Rail class D3/12 was a class of three experimental diesel-electric shunting locomotives designed by Richard Maunsell of the Southern Railway in 1937. They quickly proved their effectiveness, and although they were not immediately replicated due to the advent of the Second World War, the class were the basis for a larger class of similar locomotives introduced by Oliver Bulleid in 1949.
LMS diesel shunter 7051 was built by the Hunslet Engine Company to demonstrate its wares. After public exhibition in February 1932, it was used for trials at a colliery, before being tested by the LMS. After further public exhibition in February 1933, it was at last purchased by the LMS in May 1933. It was loaned to the War Department from August 1940, which numbered it 27. During 1941–1944 it was returned to the LMS, but in August 1944 it returned to the WD, now numbered 70027. After the end of World War II it was returned to the LMS, but was withdrawn in December 1945 and resold back to Hunslet. Hunslet used the locomotive as a works shunter, but it was also available for hire, and spent time at oil refineries in Essex and with British Railways.
LMS diesel shunter 7052 was an experimental 0-6-0 diesel-mechanical shunting locomotive, introduced by the London Midland and Scottish Railway (LMSR) in 1934 and which remained in service with that railway for six years. It was later acquired for military use until 1966.
