We are delighted to present the stunning all-new Bachmann Branchline Class 37/4 as Refurbished loco No. 37423 ‘Sir Murray Morrison’ in BR Railfreight Metals Sector livery with SOUND FITTED.
 
The British Rail Class 37 is a favourite among enthusiasts and modellers alike, and this iconic loco returns to the Bachmann Branchline range for 2022, but not as you know it. Following in the footsteps of the award-winning Bachmann Branchline Class 47, our all-new OO scale Class 37 has been designed from the rails up to ensure this classic locomotive is modelled more accurately than ever before, whilst the technical specification is equally impressive and incorporates the same great features as our Class 47. With high fidelity mouldings, numerous separately fitted parts and countless tooling variations to capture the minutiae of the real locomotives throughout their lives, our new 37 is brought to life with an exquisite livery application using true-to-prototype colours, fonts and logos. Along with an unprecedented array of lighting features, our Dual Fitted speaker system is fitted to all models – bringing this SOUND FITTED model to life.

CLASS 37 HISTORY
 
The British Rail 1955 Modernisation Plan paved the way for the large-scale replacement of steam traction with diesel locomotives, and one of the most successful diesel locomotive designs to result from this was the English Electric Type 3. These 1,700hp Types 3 diesel-electric locomotives were built at English Electric’s Vulcan Foundry and by Robert Stephenson & Hawthorns between 1960 and 1965, with 309 examples produced in total. When TOPS was implemented the type was designated Class 37.
 
The class proved popular with railwaymen and so in 1985, a major refurbishment programme for the Class 37 locomotives was sanctioned to extend the working lives of 135 locomotives. Features of the refurbishment involved plating over the four-character head codes and sealing off the nose end communication doors. Dedicated freight locomotives received lower gearing to increase the tractive effort, and some were fitted with extra ballast or even more powerful engines. A new subclass was created for locomotives refurbished with Electric Train Heating (ETH) equipment, allowing their use on passenger trains the whole year-round.
 
With the sectorisation of British Rail taking hold in the early-1980s, the locomotives returned to traffic following refurbishment in a wide and diverse range of liveries. Passenger machines appeared in BR Blue Large Logo, InterCity and Regional Railways schemes to name just three, whilst freight engines received numerous varieties of Railfreight livery, Transrail, Mainline and Loadhaul. The Class continued to be widely used into the Privatisation-era, with examples operating for the likes of EWS, DRS, West Coast Railways and Colas, whilst others have received ‘retro’ heritage repaints.
