ITT we post weird DIY/homemade trains.
Here are some that snake around the rural jungles of Ecuador. They look poor as hell but you have to admire the ingenuity to create such a weird contraption complete with all sorts of different rail lines, branches, spurs and lots of homemade locomotives. It's the sort of cool thing you'd imagine creating as a child. Sorry for the gay videos.
