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 (reference 35‑431SF) is an OO‑scale (4 mm) model of a British Rail diesel locomotive in the West Coast Railways Company Maroon livery, carrying the running number 47826. The model represents the British Rail sectorisation period and is supplied in a pristine condition with a length of 255 mm.

The locomotive is equipped with interior lighting and a DCC‑only sound decoder (ESU Loksound V5DCC). It features the Bach‑Up Stay Alive system to maintain power and prevent stalling, light flicker and sound cut‑outs. Both the Sound Fitted and Sound Fitted Deluxe versions use a dual fitted XL speaker system, including a patented enhanced‑bass passive radiator. The Deluxe version adds motorised radiator fans, tinted windscreen glazing and auto‑release couplings that uncouple on a single DCC function.

Key mechanical details include a five‑pole, twin‑shaft motor with two flywheels driving both bogies, all‑axle drive, metal bearings on each axle and die‑cast metal chassis and bogie towers. Wheels conform to NEM310/311 standards and detachable NEM362 coupling pockets are fitted, with auto‑release couplings at each end on the Deluxe version. The model is designed to run on curves of second radius (438 mm) or greater.

Additional detailing comprises plated headcode panels with sealed‑beam marker lights, twin bufferbeam brackets, a cut‑cab layout, bufferbeam‑mounted ETH equipment, single‑arm windscreen wipers, high‑intensity headlight, round buffers, a checker‑plate kickplate, full cab roof vents, Serck radiator grilles, ribbed exhaust panels and later‑type extended‑range fuel tanks. The model was voted Model of the Year 2021 and its Sound Fitted Deluxe specification won Innovation of the Year.
