Built as my COVID project, to design a modular train system to border Micropolis layouts. The Track modules have twin tracks, plus street and sidewalk, and add 8-studs to the standard city grid along the “front” (long) side of the city. The track modules for the “short side” of the city are 6-studs wide, with no road and sidewalk. It’s built for Micropolis 2, so that wires can pass underneath to reach other MOCs.
