A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight.
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.
D0280 Falcon was a single prototype diesel-electric locomotive, built for British Railways in 1961. It was one of a series of three prototypes: Falcon, DP2 and Lion, eventually leading to the Class 47 and Class 50. A requirement was expressed by the BTC at a meeting on 15 January 1960 for new Type 4 designs of Co-Co arrangement, which would be lighter than the earlier 1Co-Co1 locomotives such as the Peak classes, produced under the Pilot Scheme.
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 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 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 Forty seven examples were built, and the last were withdrawn from service in 1994.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.
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.
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.
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 Rolls-RoyceC range was a series of in-line 4, 6 and 8 cylinder diesel engines used in small railway locomotives, construction vehicles, marine and similar applications. They were manufactured by the Rolls-Royce Oil Engine Division headed by W. A. Robotham to 1963, initially at Derby and later at Shrewsbury, from the 1950s through to 1970s.
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 Dash 8 Series is a line of diesel-electric freight locomotives built by GE Transportation. It replaced the Dash 7 Series in the mid-1980s, and was superseded by the Dash 9 Series for freight usage and the Genesis Series for passenger usage in the mid-1990s.
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.
