Manufacturer description

Bachmann’s award-winning Class 47 is back, and our brilliant Brush is better than ever following a brief spell in the works to add further enhancements to this stunning OO scale model.

After winning a public vote to be crowned Model of the Year 2021, the Bachmann Branchline Class 47 has a proven track record, and now we’ve taken things to the next level with an even higher technical specification alongside refinements to two key details.

Every Branchline Class 47 now comes with our Bach-Up Stay Alive System pre-installed, providing uninterrupted power when running on DCC to eliminate stalling, light flicker and sound cut-outs. Talking of sound and our SOUND FITTED and SOUND FITTED DELUXE models now boast the Dual Fitted XL speaker system, combining two speakers for optimum sound reproduction – including the new enhanced bass reproduction speaker, a patented component which incorporates a passive radiator design for sound effects like you’ve never experienced before.

Not only was the Class 47 crowned Model of the Year in 2021 but our SOUND FITTED DELUXE features – motorised radiator fans and tinted windscreen glazing – were voted the Innovation of the Year and the SOUND FITTED DELUXE specification just got better with the addition of our revolutionary Auto-Release Couplings, fitted at either end to provide hands-free DCC uncoupling at the press of a single function button.

To define the Class 47 look we’ve turned our attention to the cab windscreen glazing and made improvements to the fit and finish of this important area. Snowploughs were a significant feature of some Class 47s too, and we’ve totally redesigned this component which now attaches to the chassis of the locomotive, providing a fixed position for a realistic appearance even when running on curved track, and allowing the bufferbeam detail to be fitted at the same time.

These enhancements only add to the stunning model that is the Branchline Class 47, with its high fidelity mouldings, a wealth of fitted parts and countless tooling variations to capture the minutiae of the real locomotives throughout their lives - ensuring each model is faithful to its prototype.

CLASS 47 HISTORY

Towards the end of the 1950s, British Railways began planning a new fleet of diesel locomotives and after investigating several prototypes, BR decided to place an order with Brush Engineering for 20 locomotives during February 1961. The resulting design became the iconic Brush Type 4 Diesel locomotive, a practical, versatile design with a very distinctive cab. Powered with a Sulzer engine and initially rated at 2,750hp, the locomotive could achieve a top speed of 75mph with a tractive effort of 55,000lb. Building commenced in January 1962 and the first locomotive No. D1500 appeared in late September of the same year with test runs on the London Midland Region and Western Region. The design was a success and BR went on to order a total of 512 with continuous production through to early 1967, forming the largest single class of main-line diesel locomotives in the UK.

During this time and subsequent years, several variations appeared with an increase in speed and tractive effort to 95mph and 62,000lb respectively. Originally fitted with four character train reporting head-codes, these changed to marker lights, with the addition of high intensity lights and roof aerials in the late 1980s. Other variations involved the fitting of different types of steam heating boiler for early BR coaching stock, later replaced with electric train heating for use with modern rolling stock. The numbering system started with four figures but changed to five with the introduction of the TOPS coding system which saw the locomotives classified as Class 47 Diesels with variations such as 47/0, 47/2, 47/3, 47/4 and 47/7. By the end of the 1990s, half of the Class 47 fleet had been withdrawn or scrapped, 33 have been converted into Class 57 locomotives and several have been preserved, including the original No. D1500, now numbered 47401.

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 Class 47/4 (model 35‑431) reproduces a British Rail Class 47 locomotive in the West Coast Railways Company maroon livery, running number 47826. The OO‑scale model measures 255 mm in length and represents the British Rail sectorisation era (Era 9). It is supplied with a Plux 22 DCC decoder socket and the recommended decoder item No 36‑570A.

Technical features include a five‑pole twin‑shaft motor with all‑axle drive, die‑cast metal chassis and bogie towers, and metal bearings on each axle. The locomotive is fitted with the Bach‑Up Stay Alive system for uninterrupted power on DCC, and the Dual Fitted XL speaker system, a patented passive‑radiator design that provides enhanced bass reproduction. The Sound Fitted Deluxe version also incorporates motorised radiator fans, tinted windscreen glazing and auto‑release couplings that can be uncoupled hands‑free by a single DCC function.

Detail refinements specific to this model are plated headcode panels with sealed‑beam marker lights, twin bufferbeam brackets, a cut‑cab layout, bufferbeam‑mounted ETH equipment, single‑arm windscreens wipers, high‑intensity headlights, round buffers, a checker‑plate kick‑plate, full cab roof vents, Serck radiator grilles, ribbed exhaust panels and later‑type extended‑range fuel tanks. Snow‑ploughs are now fixed to the chassis for realistic appearance on curves, and the model includes a slow‑speed speedo drive at the No. 2 end.

The locomotive is supplied with pre‑installed ESU Loksound V5DCC sound decoder (for Sound Fitted versions), directional lighting that can be switched on or off at either end, and authentic BR colour specifications applied by multi‑stage tampo printing. It is designed to run on curves of second‑radius (438 mm) or greater and is suitable for both DCC and analogue operation. The model reflects the historical development of the Class 47 fleet, which entered service from 1962 and was later subdivided into sub‑classes such as 47/4 during the sectorisation period.
