Accurascale expands Class 66 range with prototype-accurate OO models

Accurascale’s third Class 66 OO run is a good reminder that modern freight modeling has moved past the era of “close enough.” On a class that first arrived in Britain on April 18, 1998, and quickly became a constant on UK freight, the difference now is not the basic shape of the diesel. It is whether the model matches the right era, the right fittings and the right livery treatment.

That is why this release matters. Accurascale has treated the Class 66 as a family, not a single paint scheme, and this latest batch stretches from the type’s introduction to the present day. The line-up includes DB Cargo’s 66017 in red, Freightliner’s 66501 in 60 orange with Spirit of ’65 branding, Ocean Network Express’ 66587 in magenta with As One, We Can, and 66601 in dark green commemorative form. For modern-image layouts, that mix is the point: one class, but multiple identities, each tied to a specific prototype moment.

The tooling changes show where the hobby has got sharper. Accurascale says the new run includes a newly tooled exhaust silencer with a revised profile, improved detailing, handbrake linkages moulded in the off position, an etched middle handrail bracket where appropriate, roof-mounted Wi-Fi pod representation, Freightliner cab door handle modifications, BMAC replacement lighting units and revised buffer beam configurations. Retailer listings add more prototype variation through new buffer-plate combinations. Those are not headline-grabbing changes on their own, but they are exactly the sort of corrections that separate a good-looking diesel from a model that feels like a specific loco on a specific day.

The most notable prototype in the batch is 66601. The 66/6 sub-class covers 25 locomotives, numbered 66601 to 66625, built with a lower gear ratio for heavier trains. Accurascale says 66601 arrived aboard the M.V. Stellanova on November 13, 2000, was originally named The Hope Valley and was repainted into dark green with commemorative decals at Eastleigh in March 2025. That kind of backstory gives the model real-world weight, especially for anyone building a freight roster that mirrors contemporary practice rather than a generic “Class 66” stand-in.

There is also a human side to the story. DB Cargo locomotive 66091 was named Accurascale on July 19, 2025, at DB Cargo UK’s Family Day at Midland Railway - Butterley, with Pete Waterman performing the naming. The charity link is no footnote either: Accurascale says the limited-edition 66190 model raised £10,000 for Martin House Children’s Hospice, and its Class 66 charity projects have raised £45,000 in total. For OO modelers who run modern freight because they want their fleet to look like the real railway, this is the run that makes the case for upgrading.
