A switcher locomotive, shunter locomotive, or shifter locomotive is a locomotive used for maneuvering railway vehicles over short distances. Switchers do not usually move trains over long distances, instead they typically assemble trains in order for another locomotive to take over. Switchers often operate in a railyard or make short transfer runs. They may serve as the primary motive power on short branch lines or switching and terminal railroads.
The British Rail Class 01 diesel locomotive is a short wheelbase 0-4-0 diesel-mechanical design intended for use in areas with tight curves and limited clearance.
The British Rail Class 02 are a class of twenty 0-4-0 diesel-hydraulic shunting locomotives built by the Yorkshire Engine Company in 1960 and 1961 (D2860-D2869) for service in areas of restricted loading gauge and curvature such as docks. They had the door to the cab at the rear, with a railed veranda behind the cab; this feature was very unusual on British Rail locomotives, although it was used on many Yorkshire Engine Co. designs and is quite normal in North American practice.
The British Rail Class 03 locomotive was, together with the similar Class 04, one of British Railways' most successful 0-6-0 diesel-mechanical shunters. 230 were built at Doncaster and Swindon works between 1957 and 1962, and were numbered D2000–D2199 and D2370–D2399. D2370 and D2371 were used as departmental locomotives and originally numbered 91 and 92 respectively.
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 05 is a class of 0-6-0 diesel-mechanical shunters built by Hunslet Engine Company from 1955 to 1961. They were used on the Eastern and Scottish Regions of British Railways. The first two batches were delivered as 11136-11143 and 11161-11176. Subsequent locomotives were delivered, new, as D2574-D2618.
The British Rail Class 06 is a class of 0-4-0 diesel-mechanical shunters built by Andrew Barclay Sons and Company from 1958 to 1960 for use on the Scottish Region of British Railways. They were originally numbered D2410–D2444 and survivors after 1973 were given the TOPS numbers 06001–06010.
The British Rail Class 07 diesel locomotive is an off-centre cab 0-6-0 diesel-electric shunter type built by Ruston & Hornsby in 1962 for the Southern Region of British Railways. The 14 members of the class were primarily used at Southampton Docks and later also at Eastleigh Works.
The British Rail Class 08 is a class of diesel-electric shunting locomotives built by British Railways (BR). As the standard BR general-purpose diesel shunter, the class became a familiar sight at major stations and freight yards. Since their introduction in 1952, however, the nature of rail traffic in Britain has changed considerably. Freight trains are now mostly fixed rakes of wagons, and passenger trains are mostly multiple units or have Driving Van Trailers, neither requiring the attention of a shunting locomotive. Consequently, a large proportion of the class has been withdrawn from mainline use and stored, scrapped, exported or sold to industrial or heritage railways.
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 13 was a type of diesel-electric shunting locomotive. The type was designed in 1965 because of the need to provide more powerful shunters for the Tinsley Marshalling Yard. Due to Tinsley's status as a hump yard, it was not possible to use a single locomotive owing to the risk of grounding. So, to achieve the required power, a pair of Class 08 shunters were permanently coupled in 'master and slave' formation, with the slave unit having had its cab removed. Both units were then ballasted to improve traction. Initially coupled cab-to-cab, it was found more practical to couple master nose to slave cab.
The Hunslet Engine Company is a locomotive building company, founded in 1864 in Hunslet, England. It manufactured steam locomotives for over 100 years and currently manufactures diesel shunting locomotives. The company owns a substantial fleet of Industrial and depot shunting locomotives which are available for hire. The company is part of Ed Murray & Sons Ltd.
The British Railways Class D3/7 is a class of 0-6-0 diesel electric shunting locomotives built as LMS Nos. 7080–7119. The class were built from May 1939 through to July 1942 by the London, Midland and Scottish Railway at their Derby Works using a diesel electric transmission supplied by English Electric.
The Yorkshire Engine Company Janus is a line of 0-6-0 wheel arrangement, diesel-electric locomotives that weighed 48 long tons and had a maximum speed of 23 mph (37 km/h). The two Rolls-Royce C6SFL diesel engines gave a total power output of 400 hp (300 kW). Each engine had its cooling system at the outer end, and its generator at the inner end. There were two traction motors, each being powered by one generator, thus simplifying the electrical system.
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.
The British Rail Class 97/6 0-6-0 diesel shunting locomotives were purpose-built for departmental duties by Ruston & Hornsby at Lincoln in 1953 (97650) or 1959 (97651-654). There are minor technical differences between 97650 and the 1959 batch.
The F Class are a class of diesel locomotive shunters built by Dick Kerr Works for the Victorian Railways between 1951 and 1953. They are similar to the British Rail Class 11 and NS Class 600 shunting locomotives also built by English Electric during this period, but modified for use on the VR's 5 ft 3 in (1,600 mm) broad gauge.
Heritage Shunters Trust (HST) is a trading name of The South Yorkshire Railway Co. Ltd. which was founded in 1989.
The NZR DS class locomotive is a type of 16 diesel shunting locomotives built by the Vulcan Foundry and supplied by the Drewry Car Co from 1949–1955, for New Zealand Railways (NZR).
The China Railways "Dongfang Hong" diesel-hydraulic locomotive classes DFH2, DFH5, DFH6, and DFH7, built from the 1970s to 1990s, were all used as shunters on the Chinese railway network.
