Nick, this is the second time I've created an aerial O gauge railroad...first about 10 years ago 1 foot down from ceiling of the basement...this one is 1 foot down from the ceiling of my den. Basically encircles the den with two large reversing loops and four turnout switches. Railway is built, track laid...working on the electrical parts now. Hope to finish in a couple of weeks, and will then provide pictures and video. In my opinion it is epic!!!
