Accurascale have announced a new run of their super popular Class 66 diesel locomotives in OO Gauge, with seven new variations expected in Q2 2025!


As with previous runs of the Class 66, these are to be produced in limited quantities, so we advise you to pre-order ASAP to avoid missing out.


As per the first run of Class 66 and along with Accurascale’s other diesel an electric locomotives, each running number will be available in both DC/DCC ready and fully loaded DCC sound fitted formats, with the latter benefiting from a full suite of Accurathrash goodness as well as all the incredible tech you expect to find in Accurascale’s locomotives. With a powerful all-wheel drive arrangement, a weightily diecast chassis set-up and all Accurascale’s all-powerful evolutionary motor and drivetrain set up, they're ready to pull a house down and cope with the heaviest loads on your layout.


Priced at £179.95 for DC/DCC Ready and £279.95 for DCC Sound Fitted, they once again represent excellent bang for buck which is a hallmark of Accurascale’s philosophy of "realistic models at realistic prices", where modellers receive a market leading product and a most reasonable price! It also features all the technology you come to expect from Accurascale, such as multiple lighting models and, of course, their industry leading limited lifetime warranty!

Prototype Information

Class 66

The Class 66 is a six-axle diesel-electric freight locomotive, somewhat based on the earlier Class 59 locomotives. The class has proved to be highly successful with a total production run of 480 in the UK (with additional locos imported from overseas following this) and alternative versions of the loco being marketed to Europe as the EMD Class 66. 


Upon privatisation, a number of newly-privatised rail freight companies; Transrail, Mainline, Loadhaul, Railfreight Distribution, and RES were bought out and became EWS. EWS inherited a fleet of 1,600 mostly diesel locomotives, including many Class 47s which had to be overhauled every 7 years at a cost of £400,000. In an effort to reduce their operating costs, EWS approached Electro-Motive Diesel to build new locomotives based on the Class 59 bodyshell but with a different engine and traction motors to enable higher speed running - leading to the commissioning of the Class 66. 


EWS ordered 250 Class 66 locos, in what was termed "the biggest British loco order since steam days". Further orders were placed by Freightliner, GB Railfreight, and Direct Rail Services in later years. 66779 was the last Class 66 to be built as the design could no longer meet the stringent stage 3b emissions regulations. The locomotives have proved to be extremely reliable and adaptable, being used for across a huge spectrum of UK freight operations.
