The Class 47 was British Railways’ most prolific class of main-line diesel locomotive and so it’s no surprise that high fidelity models of these ever-popular machines are available in N Scale as part of the flagship Graham Farish range. Such were the variations that appeared across the fleet, whether from new or following modifications or refurbishment, that various sub-classes were used to highlight particular features and the Class 47/4s were those locomotives fitted with Electric Train Heating such as No. 47425 ‘Holbeck’. 
This model takes full advantage to the recent upgrades that have benefited the Graham Farish Class 47, namely the technical advancements which see the model boasting a Next18 DCC decoder interface, pre-fitted speaker, cab lighting (when used on DCC) and independent control of the directional lights at each end. The Next18 interface and pre-fitted speaker are put to full use in this SOUND FITTED model, bringing an added dimension to your model railway straight out of the box!
