That is sooooooo cool. Hubby and I were talking just this week about how many times The Wizard of Oz is referenced in Fringe, but I never saw this. When watching this scene, I was too focused on the CN logo on the side of the Train, because it is the logo for Canadian National Railway and I love anything Canadian when it's featured on TV or in movies.

Just watched this video tonight don't recall if I had seen it before and YouTube didn't show that I had watched it, so I feel like I've never seen it.
