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.

The Bachmann Branchline Class 20/0 is a new tooling project introduced in 2021, featuring a BR Blue weathered finish and disc headcodes. This OO scale model represents a Class 20 locomotive, a type of diesel engine built by British Rail from 1957 to 1968. The model is DCC ready and features a Plux 22 socket, five pole and twin flywheel motor, and directional and interior lighting. It has a length of 190mm and a minimum radius curve of 2nd radius (438mm).

The model is equipped with a range of features, including disc headcodes, large cab side windows, and fluted bogie equalising beams. It also has a mechanical speedo drive and battery boxes with additional cover clips. The model is supplied with a set of decorated bufferbeam pipework and accessory parts.

The Class 20/0 was a successful design that was built to meet the British Railways Board's modernisation plan in the 1950s. A total of 228 locomotives were built, with the first batch being introduced in 1957. The locomotives were primarily used for freight work but also saw service on passenger trains. They were later withdrawn from service in the late 1980s, but some have been preserved and are still in operation today.

The Bachmann Branchline Class 20/0 model is a detailed representation of these iconic locomotives, with accurate liveries, logos, and typefaces. It is available in a range of variants, including a weathered BR Blue finish with disc headcodes. The model is designed to operate on curves of second radius (438mm) or greater and is suitable for use with DCC and analogue control systems.
