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 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 12 is a diesel locomotive built primarily for shunting duties around London.
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.
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 Forty seven examples were built, and the last were withdrawn from service in 1994.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 EMC E3 is a 2,000 horsepower (1,500 kW), A1A-A1A diesel-electric passenger locomotive that was manufactured by Electro-Motive Corporation of La Grange, Illinois as part of the E Series of EMC/EMD diesel passenger locomotives. The EMC demonstrator #822 was released from La Grange for test on September 12, 1938. The cab version, or E3A, was manufactured from September 1938 to June 1940, and 17 were produced. The booster version, or E3B, was manufactured in March 1939 and September 1939, and 2 were produced. The 2,000 hp (1,500 kW) was achieved by putting two 1,000 horsepower (750 kW), 12-cylinder, model 567 engines in the engine compartment. Each engine drove its own electrical generator to power the traction motors. The E3 was the fourth model in a long line of passenger diesels of similar design known as EMD E-units.
HS4000 Kestrel was a prototype high-powered mainline diesel locomotive that was built in 1967 by Brush Traction, Loughborough, as a technology demonstrator for potential future British Rail and export orders. The locomotive number is a combination of the initials of Hawker Siddeley and the power rating of its Sulzer diesel engine (4,000 hp), making it the most powerful locomotive built by the company.
EMD E-units were a line of passenger train streamliner diesel locomotives built by the General Motors Electro-Motive Division (EMD) and its predecessor the Electro-Motive Corporation (EMC). Final assembly for all E-units was in La Grange, Illinois. Production ran from May 1937, to December, 1963. The name E-units refers to the model numbers given to each successive type, which all began with E. The E originally stood for eighteen hundred horsepower, the power of the earliest model, but the letter was kept for later models of higher power.
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.
The Great Western Railway purchased two diesel shunters, and ordered a further seven immediately prior to Nationalisation, which were delivered to British Rail in 1948–49. The two shunters used by the GWR were numbered 1 and 2, while a series commencing at 501 was planned for the new locomotives ordered in the 1940s. British Rail renumbered both its inherited and new locomotives in a series commencing from 15100.
The British Rail Class 43 diesel-hydraulic locomotives were built by the North British Locomotive Company (NBL) from 1960 to 1962. They were numbered D833–D865.
Sentinel Waggon Works Ltd was a British company based in Shrewsbury, Shropshire that made steam-powered lorries, railway locomotives, and later, diesel engined lorries, buses and locomotives.
A gas turbine locomotive is a type of railway locomotive in which the prime mover is a gas turbine. Several types of gas turbine locomotive have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels (drivers). A gas turbine train typically consists of two power cars, and one or more intermediate passenger cars.
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 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. They were numbered D6100-D6157. Thirty-eight of the locomotives were withdrawn by August 1968; the rest were rebuilt with bigger engines to become Class 29, although those locos only lasted until 1971.
British Railways 10100 was an unusual experimental diesel locomotive known informally as The Fell Diesel Locomotive. It was the joint production of Davey Paxman & Co, Shell Refining & Marketing Co and Lt-Col L. F. R. Fell, built for them by the London, Midland and Scottish Railway at Derby. Sir Harry Ricardo was also involved. By the time it emerged in 1950, nationalisation had taken place and it carried British Railways livery. The locomotive had six diesel engines, four of them used for traction. There were two auxiliary engines, both of which were 150 hp (110 kW) AEC 6-cylinder units, and these drove the pressure-chargers for the main engines and the purpose of this arrangement was to enable the main engines to deliver very high torque at low crankshaft speed.
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 NZR DSA class locomotive was a type of 0-6-0DM diesel-mechanical locomotives built by three different manufacturers: W. G. Bagnall, Hunslet, Mitsubishi Heavy Industries, and Vulcan Foundry for the Drewry Car Co. They were built between 1953 and 1967.
An internal combustion locomotive is a type of railway locomotive that produces its pulling power using an internal combustion engine. These locomotives are fuelled by burning fossil fuels, most commonly oil or gasoline, to produce rotational power which is transmitted to the locomotive's driving wheels by various direct or indirect transmission mechanisms. The fuel is carried on the locomotive.
