The Brush Type Twos – Class 30s and Class 31s – are the next Diesel Locomotives to get the Bachmann Branchline treatment, with models of these long-lived prototypes joining the Branchline OO scale range for the first time. Following in the footsteps of their N scale counterparts from Graham Farish, these new OO scale models have all the hallmarks of the Branchline Class 37 & 47 locomotives and more. 
Depicting a Refurbished Class 31/4 with ETH, this locomotive has had its Mirrlees engine replaced with an English Electric 12SVT and the Branchline model faithfully recreates this, with the correct roof exhaust ports and 12SVT engine block detail visible through the bodyside windows.
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 Class 31 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. This SOUND FITTED DELUXE model provides the ultimate experience, producing realistic running sounds alongside the motorised radiator fan, authentic tinted windscreen glazing and, for the first time ever, DCC-uncoupling – thanks to the Bachmann Auto-release Coupling System!
