This is an HOn30 microlayout. Total dimensions are 14"X35". I used regular n scale track and the minimum radius is 6". This is meant to be a small tourist tram on a tropical island. A small gas-electric trolley will service a dock (upper left), a beach area with a few small restaurants (lower left), a scenic tropical jungle with waterfall (lower right) and a hotel/resort area (middle). My original plan was to have some high rise art deco style hotels butt up against the vertical wall section in the middle, but now I’m rethinking it. For the gauge party, I plan to figure out what to do with this area and will add landscape/buildings to either the beach area or the jungle area.
