Bachmann 32-491

Bachmann's Description & Specifications

The Class 40 Diesel Locomotive has long been a highlight of the Bachmann Branchline OO scale fleet, and for 2023 this popular model has been upgraded to bring you more features than ever before.

With the DCC decoder interface upgraded to Plux22; new lighting features and enhanced speaker arrangements have also been employed on the Class 40 to enhance the operating experience. On track the model has a mighty presence, just like the real locomotives and, with its five pole, twin flywheel motor powering all six driving wheels, you can be sure of a performance to match too. This Class 40’s good looks are enriched by the superb livery application using true-to-prototype colours, fonts and logos to produce a model fit for any collection.

This model depicts preserved locomotive No. D345 which is presented in its current condition, carrying retro BR Green livery with small yellow panels but with the modern adornments of overhead warning flashes and orange cantrail lining. The locomotive’s unique nose end combination, with central headcode panels and high intensity headlights, is also modelled faithfully.

Class & Prototype

British Rail Class 40 "Whistlers" were iconic diesel-electric locomotives that pioneered Britain's transition from steam to diesel traction between 1958-1985. Built by English Electric with distinctive turbocharger whistles and 2000hp engines, these 200 locomotives initially worked prestigious services like the Flying Scotsman before settling into secondary passenger and freight duties. Their conservative engineering prioritized reliability over power, leading to eventual displacement by more capable designs. Seven locomotives survive in preservation, while excellent model representations from Bachmann, Graham Farish, and Heljan serve railway modellers across all scales. The class remains beloved for its pioneering role, distinctive sound, and elegant styling that defined the early diesel era.

No prototype found.

Operator & Livery

British Railways transformed Britain's fragmented rail network into a unified national system following nationalisation on 1st January 1948. Created from the "Big Four" companies under the Transport Act 1947, BR operated most of Great Britain's railways until rebranding as British Rail in 1965, managing over 20,000 route miles and inheriting nearly 20,000 locomotives of diverse designs.

The organisation pioneered standardisation through its revolutionary BR Standard locomotive programme (1951-1960), producing 999 advanced steam engines under Robert Riddles' direction. These included the versatile Britannia Pacifics, mighty 9F freight engines, and mixed-traffic classes that incorporated the best features from all predecessor companies. The 1955 Modernisation Plan accelerated diesel and electric traction development, creating fascinating mixed-traction operations.

Notable achievements included establishing unified locomotive classification systems, introducing distinctive corporate liveries, and managing the complex transition from steam to modern traction. BR's six regional structure preserved operational diversity whilst enabling standardisation of practices, signalling, and rolling stock that had eluded private enterprise for over a century.

The BR era represents steam traction's final flowering alongside emerging diesel technology, creating unparalleled locomotive variety. Today, this heritage remains highly popular with railway enthusiasts through extensive preserved fleets, heritage railway operations, and comprehensive model ranges from manufacturers like Hornby, Bachmann, and Dapol, making BR subjects essential for authentic post-war British railway modelling across all scales.

British Railways' green livery with small yellow warning panels represented a significant safety evolution during the early 1960s, combining the established prestige of the Deep Bronze Green finish with new visibility requirements for locomotive operations. The basic livery remained the standard BS224 Deep Bronze Green used on express passenger steam locomotives, maintaining visual continuity across the modernising fleet whilst incorporating practical safety improvements mandated by changing operational practices.

The distinctive feature of this livery was the addition of small yellow warning panels to the lower portion of locomotive ends, initially introduced around 1960-1962 as BR began implementing enhanced visibility measures. These panels were typically rectangular and covered only the lower section of each cab front, leaving the majority of the end in the base green colour. Many locomotives in this livery also featured additional decorative elements including grey roofs, white cab window surrounds, and various stripe configurations - some had broad horizontal grey or light-coloured stripes at solebar level, whilst others featured narrow white stripes positioned at waist height along the bodysides.

This livery variant appeared across numerous diesel classes including the Class 24, 26, 27, 35 (Hymek), 46, and others during the early-to-mid 1960s transition period. The small yellow panels were later expanded to full yellow ends from around 1966-1967, making the intermediate period with partial yellow treatment relatively brief but historically significant. Locomotives carried either the early "Lion and Wheel" or later "Lion and Crown" crests depending on their painting date, positioned centrally on the bodysides. This livery represents BR's cautious approach to safety modernisation, gradually introducing visibility improvements whilst maintaining traditional railway aesthetics before the comprehensive Rail Blue revolution transformed the entire fleet's appearance from 1965 onwards.
