The 1250 class were a class of diesel locomotive built by English Electric, Rocklea for Queensland Railways between 1959 and 1963.
The design of the 1250 class was unusual being a cab unit with a cab similar to the 1200 class but with a narrow long hood. [1] They were based on a design built for use in Brazil five years prior.
The first five units had a 1,035 kW (1,390 hp) engine and screw couplers.
The subsequent units fitted with a 1,145 kW (1,540 hp) engine, auto couplers and were wired for multiple unit operation.
They were used on ore traffic on the Great Northern line, and on general freight on the North Coast and Southern lines. [1] [2] [3] A characteristic addition to the 1250 class in 1961 was a sun visor to help reduce glare.
Two were withdrawn in the early 1980s, donating parts to the rebuild of the single 1225 class locomotive. The remainder were withdrawn in 1987. Two units have been preserved: [1] [4]

A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
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 Consequently, a large proportion of the class has been withdrawn from mainline use and stored, scrapped, exported or sold to industrial or heritage railways.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 26 diesel locomotives, also known as the BRCW Type 2, were built by the Birmingham Railway Carriage and Wagon Company (BRCW) at Smethwick in 1958–59. Forty seven examples were built, and the last were withdrawn from service in 1994. Like their higher-powered sisters, the BRCW Classes 27 and 33, they had all-steel bodies and cab ends with fibreglass cab roofs. They were numbered D5300-D5346.
The British Rail Class 73 is a British electro-diesel locomotive. This type is unusual in that it can operate on the Southern Region's 650 / 750 V DC third rail power supply, or an onboard diesel engine to allow it to be used on non-electrified routes. This makes it very versatile, although the diesel engine produces less power than is available from the third-rail power supply, so the locomotives are rarely used outside of the former Southern Region of British Rail. It is one of the first bi-mode locomotives ever built. Following the withdrawal and scrapping of the more powerful Class 74 bi-mode locomotives in 1977, the Class 73 was unique on the British railway network until the introduction of the Class 88 bi-mode locomotives in 2017. Ten locomotives have been scrapped.
A road switcher locomotive is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere.
"Bulldog nose" is the nickname given, due to their appearance, to several cab-unit diesel-electric locomotives manufactured by GM-EMD and its licensees from 1939 to 1970. The term originated with EMD F-units, as well as later E-unit models such as the E7, E8, and E9. The bulldog nose design, which has been described as a "cultural icon", consists of two narrow front cab windows, swept back above a protruding nose section, usually with a prominent nose-top mounted headlight. This bore resemblance to a dog's face. It was a blunter and more vertical variation of the early "slant nose" style, which featured a more sloped front and often less protruding headlight. Examples of this included the EMC E1.
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. All were named after Royal Navy vessels, hence the nameplates each bore a subtitle "Warship Class".
The British Rail Class 25, also known as the Sulzer Type 2, is a class of 327 diesel locomotives built between 1961 and 1967 for British Rail. They were numbered in two series, D5151–D5299 and D7500–D7677.
The X class is a class of diesel locomotives built by English Electric for the Tasmanian Government Railways between 1950 and 1952. They were the first class of diesel locomotive to enter mainline service on a Government-owned railway in Australia.
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not.
The ALCO FA was a family of B-B diesel locomotives designed to haul freight trains. The locomotives were built by a partnership of ALCO and General Electric in Schenectady, New York, between January 1946 and May 1959. Designed by General Electric's Ray Patten, they were of a cab unit design; both cab-equipped lead FA and cabless booster FB models were built. A dual passenger-freight version, the FPA/FPB, was also offered. It was equipped with a steam generator for heating passenger cars.
The New Zealand DSC class locomotive is a heavy shunting locomotive used throughout New Zealand. The class was built in seven batches, the first 18 locomotives being built by British Thomson-Houston of the United Kingdom, with the further 52 locomotives being built by New Zealand Railways (NZR).
The Y class is a class of diesel locomotives built by the Tasmanian Government Railways between 1961 and 1971.
The WAGR X class is a now-withdrawn class of diesel locomotives built by Beyer, Peacock & Company and Metropolitan-Vickers, Bowesfield Works, Stockton-on-Tees for the Western Australian Government Railways (WAGR) between 1954 and 1956. Several members of the class have been preserved.
The Victorian Railways E class was a class of electric locomotive that ran on the Victorian Railways (VR) from 1923 until 1984. Introduced shortly after the electrification of the suburban rail system in Melbourne, Australia, and based on the same electrical and traction equipment as Melbourne's early suburban electric multiple unit fleet, they provided power for suburban goods services and shunting for six decades.
The 1300 class were a class of diesel locomotive built by English Electric, Rocklea for Queensland Rail between 1967 and 1972. They were later sold to AN Tasrail.
The 1200 class were a class of diesel locomotive built by English Electric, Bradford for Queensland Railways in 1953–1954.
The GE PowerHaul is a class of mainline diesel-electric locomotives designed by General Electric. Thirty locomotives were ordered by Freightliner in 2007; the first locomotive was completed in July 2009 at GE's Erie, Pennsylvania, plant.
Diesel multiple units and railcars are trains, usually with passenger accommodation, that do not require a locomotive. Railcars can be single cars, while in multiple units cars are marshalled together with a driving position either end. As of December 2010, 23 percent of the rail passenger cars used on Network Rail are part of a diesel multiple unit.
The 1270 class were a class of diesel locomotive built by English Electric, Rocklea for Queensland Railways between 1964 and 1966.
