ANYTHING you can add would be great, I already have some info but more would be all the better. Thanks. :)
A counterweighted tow car pulls the passenger cars up the tower. At the top, the hook releases, and the cars drop. The cars have magnets on them. When the car gets down the tower far enough, conductive non-magnetic brake fins pass through the air gap between the magnets, inducing a current and causing eddy-current braking.
For details on the lift mechanism, research elevators.
For details on the braking system, research eddy current braking.
For details on the restraint system, consult this article at Virtual Midway and look at the first two sections. Intamin's hydraulic shoulder bars use exactly the same mechanism as their hydraulic lap bars.
