The file 'HO Scale Overpass (4 Trains Allowed) 3D Printer Model' is (stl) file type, size is 55.96 KB.
I tried to simplify this as best as I could for printing. Each piece can be laid flat for best quality. The overpass road itself might have to be cut up, but be careful as there is a notch for the middle support underneath. The side walls on the overpass will need four total printed, two on each side. The retaining wall is in two sections that will interlock, with the rounded side facing the trains. I should be fairly close to the scale requirements for distances between tracks to fit passing trains, track to side walls, and overpass height.
