Click over to watch the biggest version (HD) and skip ahead to around 1:30 (right after I use the Diamondback logo to fill space) and watch the track after the train passes over. I never realized it moves that much on the drop. Crazy stuff that I only noticed when I slowed the shot down.

Oh yeah, you could see it in my version as well. The copy I posed on YouTube is filled with “OMG can u see teh track shake???!!!!” comments.
