The British Rail Class 20, otherwise known as an English Electric Type 1, is a class of diesel-electric locomotive. In total, 228 locomotives in the class were built by English Electric between 1957 and 1968, the large number being in part because of the failure of other early designs in the same power range to provide reliable locomotives.
The locomotives were originally numbered D8000–D8199 and D8300–D8327. They are known by railway enthusiasts as "Choppers". [4] [5]
Designed around relatively basic technology, the 73-tonne locomotives produce 1,000 horsepower (750 kW) and can operate at up to 75 mph (121 km/h). Designed to work light mixed freight traffic, they have no train heating facilities. Locomotives up to D8127 were fitted with disc indicators in the style of the steam era; [6] when headcodes were introduced in 1960 the locomotive's design was changed to incorporate headcode boxes. Although older locomotives were not retro-fitted with headcode boxes, a few of the earlier batch acquired headcode boxes as a result of repairs. Unusually for British designs, the locomotive had a single cab. This caused serious problems with visibility when travelling nose first, though in these circumstances the driver's view is comparable to that on the steam locomotives that the Class 20s replaced. It was common, however, to find Class 20s paired together at the nose, with their cabs at opposite ends, ensuring that the driver could quite clearly see the road ahead, and a guard can watch the train from the other locomotive without the need for a brakevan.
The Class 20 saw only limited service on passenger trains. A small number were fitted with a through pipe for steam heating, primarily for use in conjunction with a Class 27 locomotive on the West Highland Line. Otherwise their use was limited to summer relief services, particularly to Skegness often under the adopted title of The Jolly Fisherman starting from various places including Burton-on-Trent, Stoke-on-Trent, Derby and Leicester. Also occasionally other holiday resorts on the east coast of England, occasional duties as a pilot, and short distance diversions of electric-hauled trains over non-electrified lines. [7] [ page needed ]
The shift of light mixed freight to the road network left British Rail with an oversupply of small locomotives. The Class 20s, however, could work in multiple and so handle heavier traffic. Most spent the majority of their working lives coupled nose to nose in pairs to provide a more useful 2,000 hp (1,500 kW) unit and to solve the visibility problems.
Most have now been withdrawn but a few remain with GBRf and other minor and industrial operators. Several that are usually operated singly have been fitted with nose-mounted video cameras as a way of solving the visibility problems.
The Série 1400 locomotives of Portuguese Railways (CP) and the G class locomotives of Midland Railway of Western Australia are based on the BR Class 20s, with the latter units featuring a different cab, based on the Jamaican Railways Class 81.

The first batch of Class 20s were allocated to Devons Road depot in Bow, London to work cross-London transfer freights, with the following eight locos allocated to Hornsey depot. After a trial with D8006, D8028–D8034 were allocated for work in highland Scotland, and had tablet catcher recesses built into the cabsides. D8035–D8044 were originally to be allocated to Norwich, but were actually used for empty coaching stock (ECS) workings in and out of London Euston. D8050–D8069 were allocated to the new Tinsley TMD in South Yorkshire, from where they regularly worked into Lincolnshire and East Yorkshire. D8070–D8127 were sent to operate in the Scottish Lowlands, particularly in the Forth-Clyde area, and the Fife coalfield. This completed the original orders for 128 locos, the last being delivered in August 1962.
With the subsequent order for a further 100 Class 20 locos, deliveries recommenced with D8128 in January 1966. Tests in 1967 using D8179 and D8317 resulted in locos from D8316 being delivered from the manufacturer with the new electronic control system for working merry-go-round (MGR) coal trains. Trains to Longannet Power Station sometimes required locos to triple-head trains. [4]
Some Class 20s were used on the construction of the Channel Tunnel and High Speed 1 and some even made their way to France to work for the Compagnie des chemins de Fer Départementaux (CFD) in industry there, although these have since been repatriated. Some locos have in the past been hired by Hunslet-Barclay to provide motive power for weedkilling trains.
The fleet of Class 20/3s owned by Direct Rail Services (DRS) has at times seen frequent work across Britain in pairs (or with Class 37s) on nuclear flask trains, the company's speciality. DRS supplies class 20s for use with the Rail Head Treatment Train in winter. Perhaps the most unusual train hauled by a Class 20 was the Kosovo Train for Life charter train in autumn 1999 which carried 800 tonnes of aid. Leaving London's Kensington Olympia station on 17 September 1999, [9] the train was hauled by 20 901, 20 902 and 20 903 throughout, reaching Prague by 20 September [10] and arriving at Pristina station at 10:00 on 25 September. [11]
DRS initially had a fleet of 15 operational Class 20/3 locomotives. Three of these have subsequently been disposed of for scrap, after stripping for spares; a further two have been sold on to Harry Needle Railroad Company (HNRC). Following the end of the 2019 Sandite season (Rail Head Treatment Trains), all of the remaining DRS Class 20/3 fleet were stood down, awaiting disposal.
In 2005 HNRC acquired a large number of 20/0s and 20/9s from the stored DRS fleet. By May 2008 HNRC had eight operational Class 20s and sixteen in storage; two were on hire at Corus Scunthorpe (nos. 81 and 82).
Over a ten-year period, concluding in 2019, a number of class 20s from HNRC were employed to deliver new S-Stock from Bombardier Transportation at Derby Litchurch Lane Works, to London Underground at Neasden depot or West Ruislip depot, for commissioning. Subsequently, immediately after the completion of deliveries, modification of these units (addition of equipment for automatic signalling) was required and they were returned to Derby in the same manner. Formation of the trains usually consisted of a pair of Class 20s, two barrier wagons, the LU S-Stock set, two barrier wagons and a dead-in-tow pair of Class 20s at the rear.

D8000 was delivered in June 1957 in overall green livery, with grey footplate, [6] red bufferbeams and a grey roof extending down the bodyside to the edge of the roof panels. [12] [ page needed ] The original batch of 10 locos bore the BR crest facing towards the nose on both sides, used yellow sans serif numerals, and had green cab roofs; locos from D8010 had the correct pattern BR crest, white numerals and grey cab roof. [6] This was adjusted after D8103 [6] to include a small yellow warning panel, although the precise size and detail of such panels varied somewhat. [4]
In 1966, D8048 was selected by the BR design panel for livery experiments and was painted in the prototype standard blue, including the bufferbeams and roof. The exceptions were the full yellow front ends and a black underframe. [13] After the adoption of Rail Blue as the BR livery, D8178 became one of the first locomotives to be delivered in this livery (along with Class 25 D7660 and Class 47 D1953) [13] and all subsequent locomotives were delivered in this livery. Despite this, some locos continued to be returned to traffic in green livery, although often with the later BR "double arrow" logo and data panel; [6] thus 20 141 was the final main line loco to carry BR green livery. [14]
Some locomotives, including 20 227, were repainted in the Railfreight grey livery with red sole bars, yellow ends and large double arrows on the sides.
At least four of the class were painted in the British Rail Telecommunications livery: [15]
Class 20/3 locomotives operated by DRS have all been painted in DRS Oxford Blue livery, with red bufferbeams and full yellow ends. There have been small variations in the shade of yellow used on these locos, and the penetration of blue from the sides onto the ends.
Class 20 locomotives operated by the Harry Needle Railroad Company (HNRC) are painted into house colours of orange and black, with yellow nose ends (20 121, 20 166, 20 311 and 20 314). Some other locomotives owned by HNRC, of subclasses 20/0 and 20/9, have been painted in a variation of two-tone Railfreight grey livery. These have dark grey roof, mid-grey upper body and light grey lower body, black underframe and buffer beam. The nose ends are painted yellow, with the lower part of the cab end in yellow and the upper part black, this continuing around the cab sides but with the light grey instead of yellow. Others are in BR Blue or Railfreight Red-stripe livery. HNRC Class 20s on long-term hire to Corus were painted in Corus livery; previously silver but currently a bright yellow with red solebar (No.81 – 20 056). Since the Corus business was bought by the Indian Tata Steel group, some of these locomotives have been repainted into Tata Blue livery (No.82 – 20 066). Two HNRC Class 20s have been painted into GBRf Europorte's blue and gold livery (20 901 and 20 905), while two other HNRC Class 20s have been painted in the White livery of Hope Construction Materials (now Breedon Cement), with a black solebar (No.2 – 20 168) and a white solebar (No.3 – 20 906).
Four locomotives carried the orange and white livery of the CFD (Compagnie de Chemins de Fer Départementaux) whilst working in France, these were 20 035, 20 063, 20 139 and 20 228.
Two locomotives, numbers 20 142 and 20 189, were briefly (for a matter of months during 2013) painted into a Balfour Beatty blue and white livery but were then returned to a variation of BR blue.
The last built class 20, number 20 227, has been used extensively on the London Underground network. In the mid-2000s it was painted in Metropolitan maroon livery and named "Sir John Betjeman" by the Class 20 Locomotive Society as acknowledgement of this work. It was repainted in a special 'modern taste' LUL-based livery, to mark the London Underground 150 celebrations but has now been repainted, again into Metropolitan maroon, but this time lined, and renamed "Sherlock Holmes". The "Sir John Betjeman" name is now carried by 20 142, which also sports Metropolitan line maroon livery.

For the 1995 James Bond film GoldenEye , a Class 20 (20 188) on the Nene Valley Railway was made to look like a Russian armoured train with the addition of fake armour. [20]
22 English-Electric Type 1 Class 20s are preserved, including the first of the class built, D8000, which is part of the National Railway Collection at the National Railway Museum in York, North Yorkshire.

A further three engines were preserved but later used for spares, then eventually scrapped. 20 035 was stripped of parts for use on fellow Gloucestershire Warwickshire Railway based classmate D8137, and later scrapped at EMR Kingsbury. 20 177 was located at the Severn Valley Railway and became a source of spare parts for D8188 & D8059; with the remains first going to C.F. Booth Ltd., Rotherham and then the cab section to The Cab Yard in south Wales. [23] 20206 was operated on the Mid-Norfolk Railway, but later sold by its owner, stripped of parts and scrapped.
In 2008 Hornby Railways launched its first version of the BR Class 20 in OO gauge. [24]
In May 2021 Bachmann Collectors Club announced a limited edition run of two London Transport models of the class 20, No. 20142 Sir John Betjeman and No. 20227 Sherlock Holmes. The models are produced in conjunction with the London Transport Museum, [25]
The British Rail Class 55, also known as a Deltic, or English Electric 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 and London King's Cross. They gained the name "Deltic" from the prototype locomotive, DP1 Deltic, 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 3,300 hp (2,500 kW). They had an official maximum speed of 100 miles per hour (160 km/h), 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 maximum in service, especially in their later years, with speeds of up to 117 miles per hour (188 km/h), being recorded on level gradients, and up to 125 miles per hour (201 km/h) whilst descending Stoke Bank.
The British Rail Class 52 is a class of 74 Type 4 diesel-hydraulic locomotives built for the Western Region of British Railways between 1961 and 1964. All were given two-word names, the first word being "Western" and thus the type became known as Westerns. They were also known as Wizzos and Thousands. The final Class 52 locomotives were withdrawn from service in 1977.
The British Rail Class 03 locomotive was, together with the similar Class 04, one of British Railways' most successful 0-6-0 diesel-mechanical shunters. 230 were built at Doncaster and Swindon works between 1957 and 1962, and were numbered D2000-D2199 and D2370-D2399. D2370 and D2371 were used as departmental locomotives and originally numbered 91 and 92 respectively.
The British Rail Class 09 is a class of 0-6-0 diesel locomotive designed primarily for shunting and short-distance freight trips along branch lines.
The British Rail Class 57 is a type of diesel locomotive that was remanufactured from Class 47s by Brush Traction of Loughborough between 1998 and 2004.
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 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.
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 to 1962. 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.
The British Railways Class 24 diesel locomotives, also known as the Sulzer Type 2, were built from 1958 to 1961. One hundred and fifty-one were built at Derby, Crewe and Darlington, the first twenty of them as part of the British Railways 1955 Modernisation Plan. This class was used as the basis for the development of the Class 25 locomotives.
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 Class 66 is a type of six-axle diesel-electric freight locomotive developed in part from the Class 59, for use on the railways of the UK. Since its introduction the class has been successful and has been sold to British and other European railway companies. In Continental Europe it is marketed as the EMD Class 66 (JT42CWR).
Railfreight Distribution was a sub-sector of British Rail, created by the division in 1987 of British Rail's previous Railfreight sector. It was responsible for non-trainload freight operations, as well as Freightliner and Intermodal services. In its early years, the division was occasionally referred to as Speedlink Distribution. It was later responsible for freight operations through the Channel Tunnel.
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 British Rail Class 50 is a class of diesel locomotives designed to haul express passenger trains at 100 mph (160 km/h). Built by English Electric at the Vulcan Foundry in Newton-le-Willows between 1967 and 1968, the Class 50s were initially on a 10-year lease from English Electric Leasing, and were employed hauling express passenger trains on the then non-electrified section of the West Coast Main Line between Crewe and Scotland. Initially numbered D400–D449 and known as English Electric Type 4s, the locomotives were purchased outright by British Rail (BR) at the end of the lease and became Class 50 in the TOPS renumbering of 1973.
The British Rail Class 92 is a dual-voltage electric locomotive, which can run on 25 kV AC from overhead wires or 750 V DC from a third rail. It was designed specifically to operate services through the Channel Tunnel between Great Britain and France. Eurotunnel indicates the Class 92 locomotive as the reference for other locomotives which railway undertakings might want to get certified for usage in the Channel tunnel.
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".
Toton Traction Maintenance Depot or Toton Sidings is a large traction maintenance depot located in Toton, Nottinghamshire. The TOPS depot code for the depot is TO. Before TOPS, the shed code was 16A.
The history of British Rail's corporate liveries is quite complex. Although from the mid-1960s to the 1980s the organisation was associated with "Rail Blue", a number of other schemes were also used, especially when it was split into operating units or "sectors" in the mid-1980s.
Network NorthWest was a brand name of British Rail which was applied for a short period to the provincial railway network in North West England. It was launched in 1989 during British Rail's sectorisation programme which created distinct brand identities for regional sub-divisions.
ScotRail was the trading name providing a distinctive brand for the British Rail network in Scotland, first adopted on 22 September 1983, under manager Chris Green, British Railways Scottish Region.
