"Excited Train Guy" reminds us a lot of the Double Rainbow dude. Excited Train Guy, you see, is really excited about trains, and doesn't mind sharing his excitement with the world. He is, after all, a self-described foamer-- a locomotive enthusiast so excited by the sight of old trains, that he or she is liable to foam at the mouth.

As one commenter on YouTube put it, "OMG it's a double trainbow!"

Watch as "Excited Train Guy" watches two train cars in North Creek, New York move back and forth along a track.
