I bet if it valleys in the cobra I would assume they'd use a cherry picker to get the people down, it would actually be faster, easier and safer than the SF home made evac platform.
I think Silverwood will have good luck with Aftershock, they have alot more time and resources to devote to DV than SF ever did, and at least a coaster that maxes out at 450pph is better suited to there than at SFGAm, though if they get rid of the seatbelts that SF had Premeir put on the train, I bet they could potentially do 800-900 pph.
