The British Rail (BR) 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"[1][2], a name derived from the distinctive beat the engine produces under load which resembles the sound of a helicopter.
Overview
Designed around relatively basic technology, the 73-ton 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[3]; 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 traveling nose first, though in these circumstances the driver's view is comparable to that on the steam locomotives that the Class 20s replaced.
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 37 locomotive on the West Highland Line. Otherwise their use on scheduled passenger services was limited to use on summer relief services, particularly to Skegness and other holiday resorts in the east of England, occasional duties as a pilot, and short distance diversions of electric-hauled trains over non-electrified lines[4].
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Most have now been withdrawn but a few remain with DRS and other minor and industrial operators. Several which are usually operated singly have been fitted with nose-mounted video cameras in order to solve the visibility problems.
Operation
British Rail
The first batch of Class 20s were allocated to Devons Road depot in Bow, London to work cross-London transfer freights, with the following 8 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 in to 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 Sheffield, from where they regularly worked into Lincolnshire and Humberside. 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[1].
After Privatisation
Some Class 20's 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. These trains sprayed a weedkiller onto the track bed.
Direct Rail Services' (DRS) fleet of Class 20/3s has at times seen frequent work across the country in pairs, or with Class 37s, on nuclear flask trains, the company's speciality. Perhaps the most unusual train hauled by a Class 20 was the Kosovo Train for Life charter train in Autumn 1999 which carried 8000 tonnes of aid. Leaving London's Kensington Olympia station on 17 September 1999[5], the train was hauled by 20901, 20902 and 20903 throughout, reaching Prague by 20 September[6] and arrived at Pristina station at 10:00 on 25 September 1999[7]
In 2005 Harry Needle Railroad Company (HNRC) acquired a large number of 20/0s and 20/9s from the DRS stored fleet. By May 2008 HNRC had 16 Class 20's in storage and 8 operational of which 2 are on hire at Corus Scunthorpe (nos 81 and 82). DRS have 10 Class 20/3 locos operational[8].
Sub-classes
| Sub-Class | Description |
|---|---|
| 20/0 | Standard as built locos |
| 20/3 (under British Rail) | Small fleet of standard Class 20/0s modified for Peak Forest aggregate workings |
| 20/3 (DRS) | DRS-owned/operated locos fitted with modified cab equipment and fully refurbished |
| 20/9 | Modified from Class 20/0 after withdrawal and sold to Hunslet-Barclay for contract freight use. Few technical differences from standard locos. Later sold to DRS and recently some to HNRC. |
Liveries
British Rail
D8000 was delivered in 1957 in overall green livery, with grey footplate[3], red bufferbeams and a grey roof extending down the bodyside to the edge of the roof panels[9]. 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.[3] This was adjusted after D8103[3] to include a small yellow warning panel, although the precise size and detail of such panels varied somewhat[1].
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.[10] 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)[10] 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[3]; thus 20141 was the final main line loco to carry BR green livery.[11]
Some locomotives, including 20227, were repainted in the Railfreight grey livery with red sole bars, yellow ends and large double arrows on the sides.
Privatisation
Class 20/9 locomotives operated by DRS have all been painted in DRS blue, with grey roof, red buffer beams 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. Some locomotives owned by HNRC, of subclasses 20/0 and 20/9, have been painted in a variation of two-tone grey livery. These have dark grey roof, mid-grey upper body and light grey lower body, black underframe and buffer beam. The nose end is painted yellow, which the lower part of the cab end is yellow and the upper part black, this continuing round the cab sides but with the light grey instead of yellow. However, HNRC class 20s on long-term hire to Corus have been painted in Corus livery; previously silver but currently a bright yellow-green with red solebar and silver cabs sides.
At least 4 of the class were painted in the BR Telecommunications livery:
20075 - Sir William Cooke - rebuilt as 20309 and in service with DRS
20128 - Guglielmo Marconi - rebuilt as 20307 and in service with DRS
20131 - Almon B. Strowger - rebuilt as 20306 and in service with DRS
20187 - Sir Charles Wheatstone - rebuilt as 20308 and in service with DRS
4 locomotives have also carried the orange and white livery of the CFD (Compagnie de Chemins de Fer Departementaux') : 20036, 20063, 20139, 20228.[12] whilst working in France.
20227 has been used extensively on the London Underground network. In the mid-2000's was painted in Metropolitan maroon livery and named "Sir John Betjeman" by the Class 20 Locomotive Society as acknowledgement of this work.
In popular culture
In the 1995 James Bond film Goldeneye, British Rail Class 20 No. D8188 was used as an escape train, with the addition of armour plating to give the impression of a Russian armoured locomotive. In addition, the distinctive engine noise was overdubbed with a more generic sound.
This fearsome looking train (British Rail Class 20 No. D8188) is an old ICBM train adapted by the villain Alec Trevelyan to become his mobile base of operations. The train is kitted out with bulletproof armour plating, an escape helicopter contained within a carriage with a removable roof, security doors and cameras.
After Bond manages to stop the train in its tracks using a Russian tank, he holds Trevelyan and Xenia Onatopp to ransom in exchange for Natalya Simonova. However, Bond shoots General Ourumov after Alec signals him to release Natalya, causing them both to be trapped. Meanwhile Alec and Xenia escape in the helicopter, leaving Bond and Natalya to escape in three minutes before the train explodes.
Preservation
A total of 25 Class 20 locomotives are preserved, including the original member of the class, D8000, as part of the National Railway Collection at the National Railway Museum in York.
In addition to the 24 locos listed above, 20177 is owned by the Somerset & Dorset Loco Company and stored at the Birmingham Railway Museum where it is being used as a source of spare parts for their other Class 20 locomotoves. As more parts are removed from this loco, it is increasingly unlikely that it will be returned to running order.
Models
In 2008, Hornby produced several of the class 20 in various liveries in 00 gauge, which were based on old Lima tooling. Bachmann Branchline (00) have their own version of the model in various liveries. Bachmann (Graham Farish) have also produced a model in various liveries in N gauge.
