Short Hood
The short hood of a hood unit-style diesel locomotive is the shorter of the two hoods (narrower sections of the locomotive body in front and behind of the cab) on a locomotive. The short hood contains ancillary equipment, frequently a chemical-retention toilet for crew use, and may contain a steam generator for heating older-style passenger cars. Styles High Normally, the short hood is the front of the locomotive, and may be referred to as the locomotive's "nose". Originally, this was not the case; railroads preferred to have the long hood leading, for additional crew protection in a collision, and because it was the familiar mode of operating steam locomotives. The requirement for increased visibility conflicted with this and ultimately gained precedence. Many locomotives originally had a short hood the full height of the locomotive (a high short hood). This gave extra equipment room and was often used to house a steam generator. Low Once the short hood was establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Class 16
The British Rail Class 16 also known as the North British Type 1 was a type of diesel locomotive designed and manufactured by the North British Locomotive Company. A total of ten were produced, these being numbered D8400-D8409. The type was ordered by British Railways (BR) as an element of the 1955 Modernisation Plan. The design was largely derived from North British's earlier prototype locomotive, designated No. 10800, produced during the late 1940s; it also incorporated several engineering approaches common to steam locomotives, the company allegedly having difficulty transitioning to the new traction format. Akin to several other Type 1 designs, they were relatively compact locomotives that were intended primarily for local freight traffic. The performance of the type was found to be lacking in comparison with its peers, thus the potential for follow-on orders evaporated and no further examples were constructed beyond the original batch. The Class 16 shared numerous design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 15
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 Class 15 was ordered by British Railways (BR) shortly after the announcement of the 1955 Modernisation Plan, which led to the procurement of a diverse number of diesel locomotives under the 'pilot scheme'. Shortly following the completion of the first locomotive during 1957, its performance was sufficient to justify multiple follow-on orders, leading to a total fleet of 44 locomotives. In service, the type was relatively unreliable, much of this been traceable to its Paxman (engines), Paxman 16YHXL power unit. Its fortunes were further impacted by inconsistent policy making. During the late 1960s, it was decided to withdraw the Class 15 in favour of the more numerous and successful British Rail Class 20 locomotive, both types hav ...

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 ...

British Rail Class 45
The British Rail Class 45 or Sulzer Type 4 are diesel locomotives built by British Railways' Derby Works, Derby and Crewe Works between 1960 and 1962. Along with the similar British Rail Class 44, Class 44 and British Rail Class 46, 46 locomotives, they became known as ''Peaks''. Technical details Engine The engine of the Class 45 was a marine-type, slow-revving diesel, a Sulzer (manufacturer), Sulzer 12LDA28B with a Bore (engine), bore of (hence the 28 in the engine designation) and a Stroke (engine), stroke of . This gave per cylinder, or for the whole engine. The unit was Turbocharger, turbocharged and Intercooler, intercooled and gave at 750 Revolutions per minute, rpm. The engine was of the U engine, double bank type with two parallel banks of 6 cylinders, geared together to a single output shaft. Six-cylinder versions of the engine were fitted in the British Rail Class 25, Class 25 locos (amongst others) and eight-cylinder versions in British Rail Class 33, Cl ...

British Rail Class 40
The British Rail Class 40 is a type of British railway diesel electric locomotive. A total of 200 were built by English Electric between 1958 and 1962. They were numbered D200-D399. Despite their initial success, by the time the last examples were entering service they were already being replaced on some top-level duties by more powerful locomotives. As they were slowly relegated from express passenger uses, the type found work on secondary passenger and freight services where they worked for many years. The final locomotives ended regular service in 1985. The locomotives were commonly known as "Whistlers" because of the distinctive noise made by their turbochargers. Origins The origins of the Class 40 fleet lay in the prototype diesel locomotives (British Rail Class D16/1, LMS No. 10000 and 10001 ordered by the London, Midland and Scottish Railway and British Railways and British Rail Class D16/2, D16/2 ordered by British Railways between 1947 and 1954) and most notably with ...

British Rail Class 37
The British Rail Class 37 is a Diesel locomotive, diesel–electric locomotive. Also known as the English Electric Type 3, the class was ordered as part of the British Rail Modernisation Plan, British Rail modernisation plan. They were numbered in two series, D6600–D6608 and D6700–D6999. The Class 37 became a familiar sight on many parts of the British Rail network, in particular forming the main motive power for InterCity (British Rail), InterCity services in East Anglia and within Scotland. They also performed well on secondary and inter-regional services for many years. Many are still in use today on freight, maintenance, and empty stock movement duties. The Class 37s are known to some railway enthusiasts as "tractors", a nickname given due to the similarities between the sound of the Class 37's engine and that of a tractor.

British Railways
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most rail transport in Great Britain from 1948 to 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board. British Railways was formed on 1 January 1948 as a result of the Transport Act 1947, which nationalisation, nationalised the Big Four (British railway companies), Big Four British railway companies along with some other (but not all) smaller railways. Profitability of the railways became a pressing concern during the 1950s, leading to multiple efforts to bolster performance, including some line closures. The History of rail transport in Great Britain 1948–1994#The Modernisation Plan, 1955 Modernisation Plan formally directed a process of dieselisation and Railway electrification in Great Britain, electrification ...

Steam Locomotives
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Hood Unit
A hood unit, in North American railroad terminology, is a body style for diesel and electric locomotives where the body is less than full-width for most of its length and walkways are on the outside. In contrast, a cab unit has a full-width carbody for the length of the locomotive and walkways inside. A hood unit has sufficient visibility to be operated in both directions from a single cab (locomotive), cab. Also, the locomotive frame is the main load-bearing member, allowing the hood to be non-structural and easily opened or even removed for maintenance. History The hood unit evolved from the switcher locomotive. A switcher's long hood is normally low enough that the crew can see over it, and there typically is no short hood. American Locomotive Company, Alco introduced the road switcher concept with the ALCO RS-1, RS-1, which was an enlarged switcher with a short hood ahead of the cab. This was added to provide protection for the crew in case of a collision. The low long ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Hood
The long hood of a hood unit-style diesel locomotive is, as the name implies, the longer of the two hoods (narrower sections of the locomotive body in front and behind of the cab) on a locomotive, particularly American-type freight locomotives. Equipment The long hood normally contains the diesel engine (prime mover), the main generator or alternator, the locomotive's cooling radiators, the dynamic brake resistor grids if fitted, and most of the locomotive's auxiliary equipment. Head-end power equipment, if fitted, is normally in the long hood; steam generators for heating older passenger cars may be either in the long or short hoods. Operating direction Normally, the long hood is the rear of the locomotive. For early hood unit models, this was not the case; railroads preferred to run with the long hood at the front and the cab at the rear (referred to as operating long hood forward or LHF). This is a holdover from the steam era of railroads where almost all locomotives were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
