British Transport Commission
The British Transport Commission (BTC) was created by Clement Attlee's post-war Labour government as a part of its nationalisation programme, to oversee railways, canals and road freight transport in Great Britain (Northern Ireland had the separate Ulster Transport Authority). Its general duty under the Transport Act 1947 was to provide an efficient, adequate, economical and properly integrated system of public inland transport and port facilities within Great Britain for passengers and goods, excluding transport by air. The BTC came into operation on 1 January 1948. Its first chairman was Lord Hurcomb, with Miles Beevor as Chief Secretary. Its main holdings were the networks and assets of the Big Four national regional railway companies: the Great Western Railway, London and North Eastern Railway, London, Midland and Scottish Railway and the Southern Railway. It also took over 55 other railway undertakings, 19 canal undertakings and 246 road haulage firms, as well as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 31
The British Rail Class 31 diesel locomotives, also known as the Brush Type 2 and previously as Class 30, were built by Brush Traction from 1957-62. They were numbered in two series, D5500-D5699 and D5800-D5862. Construction of the first locomotive was completed in the final week of September 1957, and the handing-over took place on 31 October. The first Class 31 entered service in November 1957, after the launch of the Class 20 locomotive and was one of the Pilot Scheme locomotives ordered by British Railways to replace steam traction. Engines They were originally built with Mirrlees JVS12T (D5500–D5519) and engines and Brush electrical equipment, but the engines were not successful and in 1964 D5677 was fitted with an English Electric 12SVT engine (similar to the 12CSVT used in the Class 37 but without an intercooler) rated at . The trial proved successful, and between 1965 and 1969 the entire class was re-engined. The de-rated engine was used as it was the maximum the el ...

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 12LDA28C 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. As of December 2021, 78 locomotives still exist as Class 47s, including 31 which have been preserved. 33 further locomotives were converted to Class 57s between 1998 and 2004. Origins The Class 47 history begins in the early 1960s with the stated aim of ... [...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 43 (HST)
The British Rail Class 43 (HST) is the TOPS classification used for the InterCity 125 ''High Speed Train'' (formerly Classes British Rail Class 253, 253 and British Rail Class 254, 254) power cars, built by British Rail Engineering Limited from 1975 to 1982, and in service in the UK since 1976. The class is officially the Railway speed record#Fuel-electric, fastest diesel locomotive in the world, with an absolute maximum speed of , and a regular service speed of . The record run was led by 43102 (43302) and trailed by 43159. History and background In the early 1970s, the British Railways Board made the decision to replace its main-line express diesel traction. Financial limitations were tight, so mass electrification was not possible. As a result, a new generation of high-speed diesel trains had to be developed. Experience with the high-speed British Rail Class 55, Class 55 ''Deltic'' locomotives had shown that a low axle weight was essential to avoid damage to the track at ...

British Rail Class 43 (Warship Class)
The British Rail Class 43 diesel-hydraulic locomotives were built by the North British Locomotive Company (NBL) from 1960 to 1962. They were numbered D833–D865. Classification The D800 series diesel-hydraulic 'Warship Class', of UIC classification, B-B wheel arrangement, was constructed by two different builders. Those locomotives built by British Railways at Swindon railway works, Swindon Works were originally numbered D800-D832 and D866-D870. They were allocated Class 42 under the 1968 classification system, while those built by the North British Locomotive Company (NBL) were originally numbered D833-D865 and allocated Class 43. Because of their early withdrawal dates, neither the Swindon- nor the NBL-built locomotives carried TOPS numbers. More detail on factors common to both types can be found in the article on the Swindon-built British Rail Class 42. Mechanical details The NBL-built D800s differed mechanically from the Swindon-built batch: the Swindon locomotives us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 42
The British Rail Class 42 ''Warship'' diesel-hydraulic locomotives were introduced in 1958. It was apparent at that time that the largest centre of expertise on diesel-hydraulic locomotives was in West Germany. The Western Region of British Railways negotiated a licence with German manufacturers to scale down the German Federal Railway's "V200" design to suit the smaller loading gauge of the British network, and to allow British manufacturers to construct the new locomotives. The resultant design bears a close resemblance, both cosmetically and in the engineering employed, to the original V200 design. Warship locomotives were divided into two batches: those built at BR's Swindon works were numbered in the series D800-D832 and D866-D870, had a maximum tractive effort of and eventually became British Rail Class 42. 33 others, D833–D865, were constructed by the North British Locomotive Company and became British Rail Class 43. They were allocated to Bristol Bath Road, Plymou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 41 (Warship Class)
The British Rail Class 41 diesel-hydraulic locomotives were built by the North British Locomotive Company in Glasgow during 1957 and 1958. Although they were withdrawn before TOPS was introduced, British Rail classified them as Class 41. All were named after Royal Navy vessels, hence the nameplates each bore a subtitle "Warship Class". History The fleet was ordered by the British Transport Commission as direct comparison with the British Rail Class 40, and were not actually wanted by the Western Region, who preferred their production fleet of D800 Warships. The D600s were the result of power politics within the BTC and the WR: the former was unwilling to sanction radical, stressed-skin lightweight construction locomotives at the time, while the latter was equally insistent that at least some of the new Type 4 power range locomotives on order be equipped with hydraulic transmission. They were much heavier than production Warships (almost compared to ) and can be regarded as stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
