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 English Electric Company Limited (EE) was a British industrial manufacturer formed after the armistice ending the fighting of World War I by amalgamating five businesses which, during the war, had been making munitions, armaments and aeroplanes.
The Ferrymead Railway is a New Zealand heritage railway built upon the track formation of New Zealand's first public railway, from Ferrymead to Christchurch, which opened on 1 December 1863. On the opening of the line to Lyttelton on 9 December 1867, the Ferrymead Railway became the Ferrymead Branch and was closed shortly thereafter. In 1964, rail enthusiasts began relaying track on the historic formation and the new 3 ft 6 in narrow gauge. Ferrymead Railway officially reopened in 1977. It now operates steam, diesel and electric trains regularly and is recognised as one of the most significant rail preservation sites in New Zealand.
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives, electric multiple units or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers.
British Rail Engineering Limited (BREL) was the railway systems engineering subsidiary of British Rail.
Brush Traction was a manufacturer and maintainer of railway locomotives in Loughborough, England whose operations have now been merged into the Wabtec company's Doncaster UK operations.
The British Rail Class 87 is a type of electric locomotive designed and built by British Rail Engineering Limited (BREL) between 1973 and 1975. A total of thirty-six locomotives were constructed, to work passenger and freight services over the West Coast Main Line (WCML).
Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, it was particularly well known for its industrial electrical equipment such as generators, steam turbines, switchgear, transformers, electronics and railway traction equipment. Metrovick holds a place in history as the builders of the first commercial transistor computer, the Metrovick 950, and the first British axial-flow jet engine, the Metropolitan-Vickers F.2. Its factory in Trafford Park, Manchester, was for most of the 20th century one of the biggest and most important heavy engineering facilities in Britain and the world.

Electro-Motive Diesel is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD is now owned by Progress Rail Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, and in 2010, EMD was sold to Progress Rail. Upon the 2005 sale, the company was renamed to Electro-Motive Diesel.
An electro-diesel locomotive is a type of locomotive that can be powered either from an electricity supply or by using the onboard diesel engine. For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose.
The British Rail Class 74 was an electro-diesel locomotive that operated on the Southern Region of British Railways, rebuilt from redundant Class 71 locomotives in the late 1960s. An electro-diesel locomotive is one that can operate either from an electrical supply, such as overhead catenary or an energised third rail, or from an onboard diesel engine. All were withdrawn between June 1976 and December 1977, and scrapped between 1977 and 1981.
Stadler Rail is a Swiss manufacturer of railway rolling stock, with an original emphasis on regional train multiple units and trams, but moving also into underground, high speed, intercity and sleeper trains. It is also producing niche products, such as being one of the last European manufacturers of rack railway rolling stock. Stadler Rail is headquartered at its place of origin in Bussnang, Switzerland. Stadler Rail employed 13,400 employees by 2022.
CSR Corporation Limited (CSR), formerly known as China South Locomotive & Rolling Stock Corp was a Chinese manufacturer of locomotive and rolling stock.
The Diesel Traction Group (DTG) is the Christchurch-based operator of a fleet of ex-New Zealand Railways Department diesel-electric locomotives. The fleet represents a full collection of New Zealand locomotive classes built by the English Electric Company and is a historically significant collection of early New Zealand diesel traction. All of the DTG's locomotives are owned by individual members through the sale of shareholdings.
