The British Rail Class 83 electric locomotives were built by English Electric at Vulcan Foundry, Newton-le-Willows as part of the West Coast Main Line electrification.
Fifteen locomotives of British Rail Class 83 were built between 1960 and 1962 by English Electric at Vulcan Foundry, as part of British Rail's policy to develop a standard electric locomotive. Five prototype classes (81-85) were built and evaluated, which eventually led to the development of the Class 86 locomotive.
Three of these locomotives were to have been built as Type B, geared for freight trains, but as it was only two were so built, becoming E3303 and E3304. [6] The third Type B, E3305, was never built as such. Instead it was used as a test bed with silicon rectifiers and transductors, [7] this being the first step towards thyristor control. It became a Type A, geared for passenger trains, and numbered E3100.
The other two Type B locomotives were eventually rebuilt as Type A, being renumbered E3098 (ex E3303) and E3099 (ex E3304). Power was provided by overhead catenary energized at 25,000 V AC.
Under the pre-TOPS British Rail classification, the first fourteen locomotives, E3024 - E3035 and E3303, E3304 (later E3098 and E3099) were Class AL3 (meaning the 3rd design of AC Locomotive). The fifteenth engine, E3100 became Class AL3/1. All fifteen were included in the TOPS numbering system, being renumbered 83001-015.
The Polish EU06 class was produced by English Electric at the same time as the Class 83s and externally they are quite similar.
The class was used to haul trains on the then newly electrified West Coast Main Line, from Birmingham, to Crewe, Manchester Piccadilly, Liverpool and later Preston. By 1965, electrification had spread south to London Euston.
As with the Class 84, the Class 83 suffered with problems due to the mercury-arc rectifiers. [8] After spending several years in storage (1967 to 1971), they were rebuilt with silicon rectifiers, as were already fitted to E3100, and dual braking between July 1970 and October 1973. [1]
The decision to reinstate the fifteen engines of Class 83 was the result of the extension of the electrification from Weaver Junction to Glasgow, which required more electric locomotives. [6] With both Class 83 and Class 84 being returned to traffic only thirty-six Class 87 were required to be built.
Electrification finally reached Glasgow in the early 1970s, allowing this class to operate the full length of the West Coast Main Line.
The last three in service (83009, 83012 and 83015) were retained for use on empty coaching stock workings from London Euston Station to Willesden. [9] [10] 83009 had previously been used at Longsight in Manchester, to convert the 25 kV AC supply to 1500 V DC, to allow testing of the Class 506 units [10] following the closure of Reddish Depot.
Two engines were withdrawn early as a result of accidents. The first was 83003, withdrawn in May 1975, which was severely damaged in an accident on 23 January 1975 at Watford [1] with a Class 86 (86209).
The second engine was 83004 which, on 24 December 1977, was severely damaged in a collision with a Class 47 at Willesden. [1] In 1983, ten of the remaining thirteen engines were withdrawn, all being sent to the Vic Berry Scrapyard in Leicester. The final three were withdrawn in 1989, with two of the three being scrapped at MC Metals of Glasgow in 1993. [11]
The locomotives always worked on power provided by overhead catenary energised at 25,000 V AC. However, the main transformer, normally operated with the four windings in series, could be operated at 6250 V AC with the transformer windings in parallel. This voltage was initially to be used where limited clearances gave concern over use of the higher voltage. Since the clearances were found to be adequate, the lower voltage connections were locked out of use. [12]
One locomotive has been preserved by the AC Locomotive Group.
The locomotive was originally preserved by Pete Waterman in 1992, and then purchased by the AC Locomotive Group in 1997. [11]

The British Rail Class 05 is a class of 0-6-0 diesel-mechanical shunters built by Hunslet Engine Company from 1955 to 1961. They were used on the Eastern and Scottish Regions of British Railways. The first two batches were delivered as 11136-11143 and 11161-11176. Subsequent locomotives were delivered, new, as D2574-D2618.
The British Rail Class 89 is a prototype electric locomotive. Only one was built, in 1986, by British Rail Engineering Limited's Crewe Works. It was used on test-trains on both the West Coast and East Coast Main Lines. The locomotive was fitted with advanced power control systems and developed more than 6,000 bhp. After being withdrawn in 1992, it was returned to service in 1996, before being again withdrawn in 2000. As of January 2021, it is in the final stages of an overhaul that will return it to the main line.
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.
The British Rail Class 86 is a class of electric locomotives built during the 1960s. Developed as a 'standard' electric locomotive from earlier prototype models, one hundred of these locomotives were built from 1965 to 1966 to haul trains on the then newly electrified West Coast Main Line (WCML) from London Euston to Birmingham, Crewe, Liverpool, Manchester and later Glasgow and Preston. Introduction of the class enabled the replacement of many steam locomotives, which were finally withdrawn by British Rail in 1968.
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.
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. It is one of the first bi-mode locomotives ever built. Following the withdrawal and scrapping of the more powerful Class 74 bi-mode locomotives in 1977, the Class 73 was unique on the British railway network until the introduction of the Class 88 bi-mode locomotives in 2017. Ten locomotives have been scrapped.
The British Rail Class 85 is an electric locomotive that was designed and produced at British Rail’s (BR) Doncaster Works during the early 1960s. While largely developed by BR, much of its systems can be attributed to the British manufacturing interest Associated Electrical Industries (AEI).
Class AM1 was allocated to the prototype AC electric multiple units, converted from fourth-rail DC electric stock in 1952 and used on the Lancaster/Morecambe/Heysham route. This route had been electrified by the Midland Railway at 6.6 kV, 25 Hz AC. These were withdrawn in 1952 and the service reverted to steam haulage. The line voltage was changed to 6.6 kV at 50 Hz in 1953 and the AM1s were introduced. Thus was a test to see if power could be drawn from the National Grid rather than railway owned power stations. The AM1s were fitted with mercury arc rectifiers but one was later converted to a solid state rectifier as a test. The stock was maintained at Meols Cop works near Southport.
The British Rail Class 419 Motor Luggage Vans were battery electric multiple unit cars built from 1959-61 by BR at Eastleigh Works.
Class 80 was the TOPS classification allocated by British Rail to the prototype 25 kV AC electric locomotive. This locomotive was built by Metropolitan-Vickers, initially as a prototype gas turbine-electric locomotive, numbered 18100. British Rail allocated the number E1000 to the locomotive following its conversion from gas turbine propulsion.
The British Rail Class 87 is a type of electric locomotive designed and built by British Rail Engineering Limited (BREL) between 1973 and 1975. A total of thirty-six locomotives were constructed, to work passenger and freight services over the West Coast Main Line (WCML).
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 mountains in England and Wales, and, along with the similar Class 45 and 46 locomotives, they became known as Peaks.
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.
The British Rail Class 81 is a class of AC electric locomotives that formerly operated on the West Coast Main Line of the London Midland Region of British Rail. Originally designated AL1, it was the first type of AC electric locomotive to be delivered to British Railways.
The British Rail Class 82 electric locomotives were designed by the British manufacturing interest Metropolitan-Vickers and produced by Beyer, Peacock and Company on behalf of British Rail (BR).
The British Rail Class 84 was a 25 kV AC electric locomotive that operated on the West Coast Main Line (WCML) of the London Midland Region.
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.
The British Rail Class 70 was a class of three third rail Co-Co electric locomotives. The initial two were built by the Southern Railway (SR) at Ashford Works in 1940–41 and 1945 and were numbered CC1 and CC2 - the Southern Railway latterly preferring French practice for locomotive numbers which also gave an indication of the wheel arrangement. Electrical equipment was designed by Alfred Raworth and the body and bogies by Oliver Bulleid. CC2 was modified slightly from the original design by C. M. Cock who had succeeded Raworth as Electrical Engineer. The third was built by British Railways in 1948 and numbered 20003.
British Rail's Class 27 comprised 69 diesel locomotives built by the Birmingham Railway Carriage and Wagon Company (BRCW) during 1961 and 1962. They were a development of the earlier Class 26; both were originally classified as the BRCW Type 2. The Class 27s were numbered D5347-D5415.
British Railways 10800 was a diesel locomotive built by the North British Locomotive Company for British Railways in 1950. It had been ordered by the London, Midland and Scottish Railway in 1946 but did not appear until after the 1948 nationalisation of the railways.
