Power for this model comes from a Tomytec TM-04 chassis, which is 4 wheel drive, 8 wheel pickup, and a traction tire on one drive wheel. The parts are hollow to easily add the weight of your choice. We prefer "Liquid Gravity" by Deluxe Materials.
The modeler can decide what type of materials to use for the sides, and what details to add, but our test model was built up with .040" square styrene rod for the roof and side supports, and .020" styrene grooved sheet for the sides, along with some .060" L angle and bits and pieces. The piping and rear railing is made from .015" phosphor bronze wire, with spots already laid out on the boiler for the sand lines and pipes. The bell and whistle assembly are brass castings from the parts bin.
The wood load is BBQ skewers, cut with old rail nippers... they're hiding more brass square stock for weights. There is enough room in the center by the chassis motor for even MORE weight if desired, we opted to leave this space available for crew figures and other details. These photos show off the insane amount of detail that can be achieved when using Frosted Extreme Detail. The truck springs, for instance, are actual coils of 3D printed plastic. When painted and weathered, you can't tell they're not real!
