Based on the
Atkinson-Walker Class A.3 engine’s later conversion to diesel power by the County Donegal
railway. This is a 3 mm scale print in Smooth Fine Detail Plastic and designed to run on a Tomy-Tec HM-01 chassis. It is printed in one piece, to be separated in the building process into the roof, body/footplate, and detail parts; these include exhaust pipe, work lamps, and basic couplings. If you wish to see how
similar models were built you can see this on the Model Engine Works blog at: http://modelengineworks.blogspot.com/2017/11/phoenix.html
There are some alternative chassis with a 16mm wheelbase available at the site below.
