Will the 1954 Godzilla with train in mouth be in the 2014 film?

Given the size and apparent bulk of Godzilla, I highly doubt that the train in the clip is going to be in his mouth. Is it possible, yes, but unlikely. I think what is more likely to happen is a portion of track on a bridge is destroyed, or it is being attacked by one of the Mutos. The reason I say this is because if Godzilla is anywhere near the 120-150 meter range which speculations places him at, putting a train in his mouth would instantly cause it to snap off at the edges of his mouth because of the size and strength of his jaws. Perhaps he is carrying it? Perhaps, but again, because of his size and bulk it's highly unlikely that he'll be forcing himself to bend over that far just to pick up a train. It would definitely be nice to see a throwback, but as with so many other aspects of this movie I think it'd be best for fans to stop asking "will they put this in?", "will they put that in?", "will they put this scene in or that monster in?" It's unproductive to ask such questions just because of coincidental evidence. Still, again, I agree that it'd be nice to see at least a few throwbacks to the 54' movie.
