CLASS 20/0 HISTORY

The British Railways Board's (BRB) 1955 modernisation plan called for a change to alternative forms of traction and manufacturers were asked to produce trial or initial designs for evaluation. English Electric adapted an existing design based on an export model for a 1,000bhp diesel and 20 were built as a pilot scheme for assessment.

The first batch was built in 1957 and the diesels were assigned to work from Devon's Road depot, East London. The design was a success from the start and by 1962 a total of 127 had been built. Following assessment of all the Type 1 diesels, BRB placed a further order increasing the total to 228 by 1968 and the design became the BR standard for 1,000bhp diesel locomotives. With the introduction of TOPS the locomotives were designated Class 20 and renumbered 20001 to 20228. The locomotives were principally designed for freight work but also saw service on summer passenger trains where train heating was not required. The Class 20s worked over the Eastern, London Midland and Scottish regions as well as into Wales and were commonly associated with coal traffic. The only drawback the Class had was its single end cab, unlike modern designs that have a cab at each end. BR resolved this problem by regularly operating the Class 20s as pairs, nose to nose, and with the combined power of 2,000bhp they were able to haul the heavier block freight trains.

BR's decision to switch to Type 5 and in particular Class 60 diesels in the late 1980s started a gradual withdrawal of the fleet, with just 28 left by 1994. A tribute to the design is that after 45 years the Class is still in service with DRS on mainline duties following refurbishment, the resulting locomotives being designated Class 20/3s. At least 28 of the class are now preserved.

Prototype information

^* Class names often change over the lifespan of a locomotive, so this is not necessarily the class name used by the operator in the period modelled.

Bachmann Branchline OO‑scale model of a British Rail Class 20/0 locomotive, number 20057, finished in pristine British Rail Blue livery. The model measures 190 mm in length, carries disc headcodes at each end and is supplied with an accessory pack that includes a selection of disc headcodes. It represents a locomotive built between 1957 and 1968 for British Rail, with a wheel arrangement of Bo‑Bo and a maximum speed of 60 mph (75 mph on later specifications).

The locomotive is DCC sound fitted and includes a 5‑pole motor with twin flywheels. It features fully functional directional and cab lighting, interior lighting and NEM coupling pockets, and the lighting can be operated via easy‑access switches or DCC. Sound functions cover engine start‑up (warm and cold), brake, single and two‑tone horns, guard’s whistle, buffer and coupling noises, wagon snatching, flange squeal and a number of ancillary sounds such as wipers and compressor. Analogue users receive basic directional lights and prime‑mover sounds directly from the box.

The model reflects the British Rail Class 20/0 as it appeared in the TOPS era, a 1 000 bhp single‑cab diesel introduced under the 1955 modernisation plan. A total of 228 units were built up to 1968; they were primarily used for freight, often operating in nose‑to‑nose pairs to provide a two‑cab configuration. The class remained in service into the 1990s and several examples are now preserved. This product was announced in the Spring 2021 British Railway announcements (21/03/2021).
