The bogie construction was fairly simple, each being made from two side beams cut from balsa using a Dremel jigsaw, joined together with a couple of 12 x 40 mm pine beams. A flat base plate was added to serve as a kind of turntable for the bogies where they attach to the pine beam on the bottom of the MDF loco base plate.

Wheels are 55mm diameter carpet protectors, intended for protecting carpets from medium sized furniture legs. I tried to make 3D printed wheels, but they didn’t look all that great… good thing the carpet protectors just happened to be the right size!
