This is an insane track.

[ezdays]

Lookie here, I can't get four feet of track with one curve to run five minutes without some sort of derailment. I can't keep ten cars on the track all at once without fiddling around for a half-hour, so I really got to hand it to this guy for getting it to run like it does. He's got this set up in his living room with the return loop on cardboard boxes, so you know this wasn't meant to be anything but a whim to go on YouTube...
