Hattons Originals Class 66

A sample of the Hattons Class 66 model locomotives

The model represents our biggest project to date, engineered from the ground-up using the very latest design and production techniques - with an all-new tooling, comprehensive detailing and a myriad of features at an affordable price. We want to produce the definitive modern era OO gauge loco and with the Class 66 now entering its third decade - we think there is no better time to do so.

Our range showcases usage of the locomotives by EWS, DB Schenker, Euro Cargo Rail, Freightliner, Direct Rail Services, GBRf and Colas Rail. This means that the lifespan of the 66 is thoroughly covered, with a variety of tooling variations and loco-specific modifications on show. You can explore the vast range of features and tooling variations that are included in the model below.

Prototype Information

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 455 in the UK 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.
