British Rail Class 55
The British Rail Class 55, also known as a Deltic, or English Electric List of British Rail power classifications#Type 5, Type 5, is a class of diesel locomotive built in 1961 and 1962 by English Electric for British Railways. Twenty-two locomotives were built, designed for the high-speed express passenger services on the East Coast Main Line (ECML) between Edinburgh Waverley railway station, Edinburgh and . They gained the name "Deltic" from the prototype locomotive, British Rail DP1, DP1 ''Deltic'' (the running number DP1 was never carried), which in turn was named after its Napier Deltic power units. At the time of their introduction into service in 1961, the Class 55s were the most powerful single-unit diesel locomotives in the world, with a power output of . They had an official maximum speed of , and introduced the first regular 100 mph diesel passenger service to Britain, they were however capable of higher speeds than this, and often exceeded their official max ...

English Electric
The English Electric Company Limited (EE) was a British industrial manufacturer formed after World War I by amalgamating five businesses which, during the war, made munitions, armaments and aeroplanes. It initially specialised in industrial electric motors and transformers, locomotives and railway electric traction, traction equipment, diesel engine, diesel motors and steam turbines. Its products were later expanded to include consumer electronics, nuclear reactors, guided missiles, military aircraft and mainframe computers. Two English Electric aircraft designs became landmarks in British aeronautical engineering; the English Electric Canberra, Canberra and the English Electric Lightning, Lightning. In 1960, English Electric Aircraft (40%) merged with Vickers Armstrongs, Vickers (40%) and Bristol Aeroplane Company, Bristol (20%) to form British Aircraft Corporation. In 1968 English Electric's operations were merged with General Electric Company#Further expansion (1961–83), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail DP1
English Electric DP1, commonly known as ''Deltic'', is a prototype demonstrator locomotive employing two Napier Deltic engines, built by English Electric in 1955. The high power of the locomotive at an acceptably low axleload resulted in 22 similar locomotives being ordered by British Railways for use on East Coast Main Line express passenger services, the serial production of which became the British Rail Class 55. Background and design The English Electric company, which had absorbed the aeroengine-maker D. Napier & Son into its group at the instruction of the Ministry of Aircraft Production in 1942, was a major builder of diesel and electric locomotives. The two George Nelsons (Sir George, and his son, known in the works as "Half") saw the potential of Napier's Deltic engine for rail traction and in 1954–1955 built a demonstrator at its Dick, Kerr works in Preston. Officially numbered DP1, its internal project title was ''Enterprise'', and it was intended that the loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Electrification
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or Rail freight transport, freight in separate cars), electric multiple units (Passenger car (rail), passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient electric power station, generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and electric transmission line, transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous electrical conductor, conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel cei ...

LNER Class A4
The LNER Class A4 is a class of streamlined 4-6-2 steam locomotive, steam locomotives designed by Nigel Gresley for the London and North Eastern Railway in 1935. Their streamlined design gave them high-speed capability as well as making them instantly recognisable, and one of the class, LNER Class A4 4468 Mallard, 4468 ''Mallard'', holds the record as the world's fastest steam locomotive. Thirty-five of the class were built to haul express passenger trains on the East Coast Main Line route from London King's Cross railway station, London Kings Cross via York railway station, York to Newcastle railway station, Newcastle, and later via Newcastle to Edinburgh Waverley railway station, Edinburgh, Scotland. They remained in service on the East Coast Main Line until the early 1960s when they were replaced by British Rail Class 55, Deltic diesel locomotives; they themselves proving to be worthy successors to the A4s. Several A4s saw out their remaining days until 1966 in Scotland, partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Region Of British Railways
The Eastern Region was a region of British Railways from 1948, whose operating area could be identified from the dark blue signs and colour schemes that adorned its station and other railway buildings. Together with the North Eastern Region (which it absorbed in 1967), it covered most lines of the former London and North Eastern Railway, except in Scotland. By 1988 the Eastern Region had been divided again into the Eastern Region and the new Anglia Region, with the boundary points being between and , and between and . The region ceased to be an operating unit in its own right in the 1980s and was wound up at the end of 1992. History The region was formed in at nationalisation in 1948, mostly out of the former Great Northern, Great Eastern and Great Central lines that were merged into the LNER in 1923. Of all the "Big Four" pre-nationalisation railway companies, the LNER was most in need of significant investment. In the immediate post-war period there was a need to rebuild ...

Bulldog Nose
"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 style was highly influential in locomotive design internationally during the same period, with many diesel and electric locomotives in Europe and Australia among other places adopting similar styling during the 1940s, 50s and 60s.

Power To Weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or r⋅min−1) is a unit of rotational speed (or rotational frequency) for rotating machines. One revolution per minute is equivalent to hertz. Standards ISO 80000-3:2019 defines a physical quantity called ''rotation'' (or ''number of revolutions''), dimensionless, whose instantaneous rate of change is called ''rotational frequency'' (or ''rate of rotation''), with units of reciprocal seconds (s−1). A related but distinct quantity for describing rotation is ''angular frequency'' (or ''angular speed'', the magnitude of angular velocity), for which the SI unit is the radian per second (rad/s). Although they have the same dimensions (reciprocal time) and base unit (s−1), the hertz (Hz) and radians per second (rad/s) are special names used to express two different but proportional ISQ quantities: frequency and angular frequency, respectively. The conversions between a frequency and an angular frequency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opposed-piston Engine
An opposed-piston engine is a piston engine in which each cylinder (engine), cylinder has a piston at both ends, and no cylinder head. Petrol and diesel opposed-piston engines have been used mostly in large applications such as ships, military tanks, and factories. Current manufacturers of opposed-piston engines include Cummins, Achates Power, and Fairbanks-Morse, Fairbanks-Morse Defense (FMDefense). Design Compared to contemporary Two-stroke engine, two-stroke engines, which use a conventional design of one piston per cylinder, the advantages of the opposed-piston engine are: * Eliminating the cylinder head and valve-train, which reduces weight, complexity, cost, heat loss, and friction loss of the engine. * Creating a Two-stroke engine#Uniflow-scavenged, uniflow-scavenged movement of gas through the combustion chamber, which avoided the drawbacks originally associated with the Two-stroke engine#Cross-flow-scavenged, crossflow-scavenged designs of early piston-engines. * A ...
