^True, but you've got to admit the structure really adds to the effect. This will be a long sweeping turn anyway, so the G's will be sustained for a good while. From what I can tell the overbank would be right up against the train tracks, and then it will drop out of that and continue curving down into the valley until it crosses over or under the base of the first drop.
As for the footers on that side of the station, I simply don't see how they could be for track. Yes, that is the maintenance bay side of the station, but there's no room for a switch track on that side. The only thing that makes sense is a walkway of some sort, potentially the exit, which would explain why it dips so much there.
