Hatton’s has revealed the final CAD drawings for its ‘O’ gauge Gresley ‘A3’ 4-6-2 covering seven different locomotives and a number of detail variations. The model is being produced by Heljan for Hatton’s with a target of release in 2018.
More details of the locomotive’s specification have also been revealed. This includes a compensated centre driving axle, a five-pole can motor with brass flywheel mounted in the boiler, provision for speakers in the boiler and tender, sprung buffers and all wheel pick up. The model is also being designed to operate down to second radius in ‘O’ gauge – the equivalent of 1,020mm radius track.
Variations include single and double chimney locomotive, with and without smoke deflectors, corridor and non-corridor tenders, dome styles and numberplate positions.
The full list of planned ‘A3s’ is available to view and pre-order on Hatton’s dedicated Gresley ‘A3’ web page.
