Well here's something you don't see every day: train tracks on fire. But what's going on here?

Did someone try and drive on the train tracks again? Is this a remnant from Superman trying to stop a speeding train?

Actually, what's happening here is a good thing. It's something called a fire snake, and it heats up railroad tracks in the winter to keep them from breaking. I did not know that!

 

That is COOL! Here's the instructional video. Don't try this at home, people!
