HO Scale Overpass (4 trains allowed)

thingiverse

I've made every effort to simplify this as much as possible for printing purposes. Each piece can be laid flat for optimal results. The overpass road itself may need to be cut into sections, but exercise caution when doing so as there's a notch that accommodates the middle support underneath. Four side walls will be required in total, with two on each side of the overpass. The retaining wall comes in two sections that interlock perfectly, with the rounded side facing the trains. I'm confident that I've met or exceeded the scale requirements for distances between tracks to allow passing trains, track positioning relative to side walls, and overpass height.
