Interesting stuff, friends of ours purchased several train cars and placed them on train tracks on their property and made them into a home. Each railcar has a specific functionality: bedrooms, formal dining room, family room, theater room, den, kitchen, game room & an atrium car. There is a separate guest railcar on a single track about 75 ft from the rest for privacy. It's a cool setup to say the least, especially the atrium car(upper sides and roof all glass). Shit, now that I think about it, probably wouldn't be considered a micro home.
