Most of the track is a dual spine set. This is a very similar style track to what's on Intimidator 305 which supports the loads of a multi ton train exuding untold tons of force as it hits speeds approaching 100MPH. Gringotts requires the dual spine simply due too the weight of its tandem trains. From on board computers to hydraulics to interactive elements these trains are loaded.The collaboration from multiple vendors on Gringotts alone is unlike anything done before. Different companies are supplying so many different aspects of the ride and for the first time that I know of competitors had to visit each others facilities to invent, install, and trouble shoot different aspects of the attraction.
I've said it once and I'll say it again, the ride system for Gringotts technologically speaking makes the FJ look as complicated as a Omnimover.
