Prototype Era
Era 11 (2016 to 2026) The Last Days of Privatisation
Exclusive to Rails of Sheffield
Prototype History
Exclusively available from Rails is Class 66/7 66747 'Made in Sheffield' in the striking Newell & Wright Group colourscheme. Celebrating the partnership between NWT and GB Railfreight, this distinctively liveried locomotive was unveiled in July 2019 and sees daily use across the entirety of GBRfs services. It has even hauled passenger services as part of the Caledonian Sleeper trains!
Based in Masborough, NWT are the largest privately owned haulage contractor in South Yorkshire, and are just as proud of their local heritage as we are at Rails, as showcased by the locomotive's name "Made In Sheffield".
Model Enhancements
Alongside the new liveries, Accurascale has implemented a number of refinements to the Class 66 tooling to ensure the models remain faithful to the evolving real-world fleet.
Enhancements include a newly tooled exhaust silencer with improved profile and detailing, revised handbrake linkages moulded in the off position, and an etched middle handrail bracket on the cab fronts for locomotives that carry this feature. Additional updates include the ability to represent roof-mounted Wi-Fi pods, Freightliner cab-door handle modifications, and locomotives fitted with BMAC-replacement lighting units.
New buffer-plate combinations have also been introduced, allowing additional prototype variations to be accurately represented within the range.

Accurascale Class 66 GBRF (Newell and Wright) No.66747 diesel locomotive – DCC Sound is a limited‑edition model released as part of the Rails of Sheffield range. It carries the manufacturer part number ACC3475‑DCC and represents a current‑era GB Railfreight locomotive.
The prototype history replicates locomotive 66747, named “Made In Sheffield”, in the Newell & Wright Group colour scheme. The real locomotive was unveiled on 01/07/2019 and is in daily use across the GB Railfreight network, including occasional haulage of Caledonian Sleeper passenger services.
Model enhancements include a newly tooled exhaust silencer with improved profile, revised handbrake linkages moulded in the off position, an etched middle handrail bracket on the cab fronts, optional roof‑mounted Wi‑Fi pods, Freightliner‑style cab‑door handle modifications and BMAC‑replacement lighting units. New buffer‑plate combinations allow additional prototype variations to be represented.
Deluxe and DCC features comprise a PowerPack capacitor for uninterrupted power, a customised dual‑speaker system – a large “Accurathrash” style bass speaker together with a smaller high‑frequency cube – and a hall sensor for flange squeal, the latter being available only on DCC‑Sound fitted models. The locomotive is DCC ready with a 21‑pin MTX socket or can be fitted with an original ESU LokSound 5 decoder.
High‑performance traction is provided by a five‑pole motor with two flywheels, gearing that enables a minimum scale top speed of 75 mph (120 km/h) and all‑wheel drive with all‑wheel pickup. The fully detailed lighting pack offers directional lighting for both DC and DCC operation, switchable red and white marker lights with day/night settings, and separately switched cab lighting that auto‑turns off when the locomotive is moving.
