Accurascale’s  Director of Product Development & Commissions, Patrick Conboy, said: “We are delighted to be working alongside KMS Railtech to produce the Class 73/9 in OO gauge. KMS are a young company with tremendous drive and ambition, and that is reflected in their decision to commission a high-spec model of these fantastic locomotives. The Class 73/9 dovetails nicely with our forthcoming Caledonian Sleeper Mk5 coaches, and together they will provide modellers with the means to recreate some of the most iconic present-day passenger services on Britain’s railway network.”
