Why would you want to make Lego Train Track from minifigures? Good question, I really don't know why, but you can, and here is how.
It does work best using powered trains, it's 100% legal (i think) so you don't need to fear the Lego Police, and no, you can't do curves.
No minifigures were harmed in the making of this dumb video.
