Class 47/7 47712 'Lady Diana Spencer' BR ScotRail - Sound Fitted version


As part of our Spring 2022 British Railway Announcements, we are delighted to present the stunning new Bachmann Branchline Class 47/7 as No. 47712 'Lady Diana Spencer' in BR ScotRail livery.

Following the release of the first of the all-new Bachmann Branchline Class 47s in late-2021, this new addition brings BR ScotRail livery to the new Class 47 for the first time. With high fidelity mouldings, numerous separately 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 – our new 47 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 new Dual Fitted speaker system is fitted to all models, bringing to life our SOUND FITTED models. For the ultimate experience, choose our SOUND FITTED DELUXE models with their ground-breaking motorised radiator fans and authentic tinted windscreen glazing!
