Multiple Working
On the rail network in Great Britain, multiple working is where two or more traction units (locomotives, diesel multiple units or electric multiple units) are coupled together in such a way that they are all under the control of one driver ( multiple-unit train control). If the front locomotive of a pair in multiple has failed the driver can still control the rear locomotive for as long as air and electricity supplies are available on the failed locomotive. "In tandem" is when more than one diesel or electric locomotive are hauling a single train and under the control of a driver on each locomotive. Locomotives In the early days of diesel locomotives in the 1960s, locomotives worked within their class (i.e. two locomotives of the same class could work together but not with other classes). Locomotives from different manufacturers had varying methods of controlling engines or braking systems. If a train required more than one locomotive, an additional driver was needed, a ...

British Rail Class 47
The British Rail Class 47 or Brush Type 4 is a class of diesel-electric locomotive that was developed in the 1960s by Brush Traction. A total of 512 Class 47s were built at Brush's Falcon Works in Loughborough and at British Railways' Crewe Works between 1962 and 1968, which made them the most numerous class of British mainline diesel locomotive. They were fitted with the Sulzer (manufacturer), Sulzer 12LDA28C U engine, twin-bank twelve-cylinder unit producing though this was later derated to to improve reliabilityand have been used on both passenger and freight trains on Britain's railways for over 55 years. Despite the introduction of more modern types of traction, a significant number are still in use, both on the mainline and on heritage railways. , 76 locomotives still exist as Class 47s, including 32 which have been preserved. 31 locomotives, including six which are preserved, retain mainline running certificates. A further 33 locomotives were converted to British Rail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 29
The British Rail Class 29 were a class of 20 diesel-electric Bo-Bo locomotives produced by the re-engining of the NBL Type 2 units. The units were designed for both passenger and freight trains. Background The machines were produced from 1963 onwards from the North British Type 2 (later Class 21 under TOPS) by replacing the original unreliable licence-built MAN engines of the Class 21s with Paxman Ventura V12 engines at Paxman's Colchester works. The first unit to be re-engined was D6123, a further 19 machines were re-engined in 1965–1967 at Glasgow Works and mostly Inverurie Works, along with other modifications including the fitting of four-character headcode displays in the nose ends (D6123 retained its original front ends and so did not receive a headcode panel). After rebuilding, they returned to service from Eastfield depot in Glasgow. The allocation of all twenty locomotives in August 1967 was Eastfield. Withdrawal Although these offered more power and much impro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 28
The British Rail Class 28 ( Metro-Vick Type 2) diesel-electric locomotives, known variously as 'Metrovicks', 'Crossleys' or 'Co-Bos', were built under the Pilot Scheme for diesel locomotives as part of the British Railways 1955 Modernisation Plan. These Crossley-engined locomotives were one of two designs built under the Pilot Scheme to use two-stroke diesel engines, the other being the Class 23 'Baby Deltic' locomotives. The locomotives had a Co-Bo wheel arrangement (a 6-wheel bogie at one end, a 4-wheel bogie at the other) – unique in British Railways practice and uncommon in other countries, although Japan also used some C-B diesel hydraulics. The maximum tractive effort of was unusually high for a Type 2 locomotive but, as there were five (not four) driving axles, the risk of wheelslip was minimal. Origin Work had begun on the Pilot Scheme in 1954 and the first plan for 174 locomotives (all classes) had been produced by October 1954, including 20 of these Metr ...

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 74
The British Rail Class 74 was an electro-diesel locomotive that operated on the Southern Region of British Railways, rebuilt from redundant British Rail Class 71, Class 71 locomotives in the late 1960s. An electro-diesel locomotive is one that can operate either from an Railway electrification system, electrical supply, such as Overhead line, overhead catenary or (in this case) 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. History Twenty-four British Rail Class 71 (pre-TOPS type HA) locomotives were built in 1958 at the British Rail works in Doncaster Works, Doncaster. Ten of these were deemed surplus to requirements and placed in storage in 1964. The work to convert these to electro-diesels was originally to have taken place at the Southern Region works at Eastleigh, but their involvement in new build EMUs for the Bournemouth electrification meant that Crewe Works was c ...

British Rail Class 73
The British Rail Class 73 is a British electro-diesel locomotive. This type is unusual in that it can operate on the Southern Region's 650 / 750 V DC third rail power supply, or an onboard diesel engine to allow it to be used on non-electrified routes. This makes it very versatile, although the diesel engine produces less power than is available from the third-rail power supply, so the locomotives are rarely used outside of the former Southern Region of British Railways, Southern Region of British Rail. It is one of the first bi-mode locomotives ever built. Following the withdrawal and scrapping of the more powerful British Rail Class 74, Class 74 bi-mode locomotives in 1977, the Class 73 was unique on the British railway network until the introduction of the British Rail Class 88, Class 88 bi-mode locomotives in 2017. Ten locomotives have been scrapped. History The Southern Railway (UK), Southern Railway's expanding third rail electric passenger network (which had begu ...

British Rail Class 46
The British Rail Class 46 is a class of diesel locomotive. They were built from 1961 to 1963 at British Railways' Derby Works and were initially numbered D138–D193. With the arrival of TOPS they were renumbered to Class 46. Along with the similar British Rail Class 44, Class 44 and British Rail Class 45, 45 locomotives, they became known as ''Peaks''. Fifty-six locomotives were built. The first was withdrawn in 1977 and all were withdrawn by the end of 1984. Overview The Class 46 design was structurally the same as the preceding British Rail Class 45, Class 45 build, and had the same Sulzer (manufacturer), Sulzer engine, but differed in the fitment of a Brush Traction, Brush generator and traction motors, in place of the Crompton Parkinson equipment fitted to the Class 45. Along with the other Sulzer class 44 and 45 designs they are often referred to as "Peaks", so named because the Class 44s were named after mountains. The British Transport Commission decided to cancel the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 44
The British Rail Class 44 or Sulzer Type 4 diesel locomotives were built by British Railways' Derby Works between 1959 and 1960, intended for express passenger services. They were originally numbered D1-D10 and named after List of P600 mountains in the British Isles, mountains in England and Wales, and, along with the similar British Rail Class 45, Class 45 and British Rail Class 46, 46 locomotives, they became known as ''Peaks''. Overview In part inspired by British Rail Class D16/1, LMS prototypes 10000 and 10001, and by British Rail Class D16/2, Southern Railway 10201-10203, the Class 44 diesels were some of the first big diesels commissioned for the British Rail modernisation project and were the precursors to the British Rail Class 45, Class 45 and British Rail Class 46, Class 46 locomotives of similar design. They were originally designed to have a Co-Co wheel arrangement, but it proved impossible to keep below the axle loading limit imposed by the British Railways Civil E ...

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 ...
