Bachmann 32-492SF

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.

Finished in BR Green livery with Full Yellow Ends we have No. 40039, a Class 40 with disc headcodes which has received its TOPS number, but still carries BR Green livery. The work-worn condition of the prototype is replicated on this Branchline model using complex weathering and fading techniques.

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.
