train set isn't just any model train set. No -- it's probably the world's smallest, most ridiculous and most awesome all at once (all at once). The so-called James River Branch community has been in the works for months on end, and the $11 working locomotive is 35,200 times smaller than a real one. Of course, the moving trains are really just attached to the top of a rotating tube, but you can certainly pretend you never heard that spoiler if you'd like. Check the video after the break -- the kid in you will thank us.
