Professionally-built coal-fired copper boiler, silver-soldered throughout, boiler feed by mechanical pump driven from crankshaft.
The engine drives through a two speed transmission with differential. There is a powerful band brake fitted on the offside third shaft and winch behind the nearside rear wheel. The straked wheels are particularly effective over soft ground and the engine comfortably pulls its driver and a couple of boys!
The engine is fitted with a mechanical lubricator and governor - most of the plumbing is in place to fit the injector (water tap, boiler clack valve).
In three inch scale the engine is a very practical size for transporting around for club events and rallies. It is 44 inches long, 29 inches to the top of the chimney and weighs around 300 pounds. It fits into the back of an estate car and can be comfortably loaded single-handed using ramps.
