This 60 ton, three truck Shay kit is based on the West Side Lumber Company #12. The multi-media kit is composed of pewter, resin and 3d printed parts. Two extensive photo-etched frets allow you to create a highly detailed operating Nn3 locomotive. To add ballast, some of the parts are cold-cast with brass filled resin. The completed kit can be operated with one or two power trucks (available separately on our website). Detailed instructions make building the kit as easy as possible.

He says "The car behind the loco is a Republic Locomotive Works West Side gasoline & diesel car. The second car is a scratch-built cordwood load. The track is Rokuhan Classic, throttle is Rokuhan RC02, water car is Showcase kit".
