Multiple Working
On the UK rail network, 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, at extra expense. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Rail Class 26
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 Forty seven examples were built, and the last were withdrawn from service in 1994.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. Origins The BR Modernisation Plan contained a large requirement for small diesel locomotives in the - range and under BR's 'Pilot Scheme', small batches of locomotives were ordered from numerous different manufacturers for evaluation. BRCW obtained an order for 20 mixed traffic diesel-electric locomotives powered by Sulzer 6LDA28 engines. The Birmingham Railway Carriage and Wagon Company was a rolling stock manufacturer, although they were building diesel multiple units for BR. The first standalone locomotives made by the company were produced in 1956-57 BRCW: ... [...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 improve ... [...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 Metro-Vi ...

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 British Rail 10800, 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 List of British Rail power classifications, 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 b ...

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 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 (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) were built in 1958 at the British Rail works in Doncaster and in 1964 ten were deemed surplus to requirements, withdrawn from service and placed in storage. The Southern Region was highly impressed with the "little-ED" JA & JB/class 73 locomotives and were keen to see a higher power locomotive with the same flexibility. In 1965, discussions were opened with English Electric (builders of the production JB/Class 73) to produce a high powered electro-diesel. Orig ...

British Rail Class 73
The British Rail Class 73 is a British electro-diesel locomotive. The type is unusual in that it can operate from the Southern Region's 650/750 V DC third-rail or an on-board diesel engine to allow it to operate on non-electrified routes. This makes it very versatile, although the diesel engine produces less power than is available from the third-rail supply so the locomotives are rarely operated outside of the former Southern Region of British Rail. Following the withdrawal and scrapping of the more powerful Class 74 electro-diesels in 1977, the Class 73 was unique on the British railway network until the introduction of the Class 88 electro-diesels in 2017. Ten locomotives have been scrapped. History The Southern Railway's expanding third rail electric passenger network (which had begun as far back as 1915) was until 1941 a purely passenger electric multiple unit (EMU) system. This was because it was necessary to have gaps in the third rail for level crossings, etc., w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Class 44 and 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 Class 45 build, and had the same Sulzer engine, but differed in the fitment of a 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 earliest of the Class 44 were named after mountains. The British Transport Commission decided to cancel the final twenty Class 46 locomotives then on order and invited bids for twenty locomotives of ...

British Rail Class 45
The British Rail Class 45 or Sulzer Type 4 are diesel locomotives built by British Railways' Derby and Crewe Works between 1960 and 1962. Along with the similar Class 44 and 46 locomotives, they became known as ''Peaks''. History The Class 45s became the main traction on the Midland Main Line from 1962, and their introduction allowed considerable acceleration of the previous steam-powered service. The Class 45s remained the main source of power on the Midland Main Line up to 1982, when they were relegated to secondary services following introduction of HSTs on the route. From 1986 Class 45s virtually disappeared from the line. From the early 1980s until their withdrawal c.1988, the class were regular performers on the North Trans-Pennine line working services from Liverpool Lime Street to York, Scarborough or Newcastle via Manchester Victoria, Huddersfield and Leeds. These trains were usually formed of early Mark 2 carriages, of up to seven in a typical train. Naming 26 C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 British mountains, and, along with the similar Class 45 and 46 locomotives, they became known as ''Peaks''. Overview In part inspired by LMS prototypes 10000 and 10001, and by 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 Class 45 and 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 Engineer. A 1-Co bogie design originally used on the Southern Railway 10201 was used instead. Construction began in the summer of 1958, although the first example was not completed until April 1 ...

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. They were, for a time, the pride of British Rail's early diesel fleet. However, 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 ( LMS No. 10000 and 10001 ordered by the London, Midland and Scottish Railway and British Railways and D16/2 ordered by British Railways between 1947 a ...

British Rail Class 37
The British Rail Class 37 is a diesel-electric locomotive. Also known as the English Electric Type 3, the class was ordered as part of the 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 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. Description Background As part of the large scale dieselisation brought about by the British Rail modernisation plan a need was identified for a number of type 3 locomotives of power output to .
