*rolls eyes* There is no difference between a sit down looper and a stand up except that it takes an extra few seconds to get situated, and that is dependant on the rider's intelligance. Straddle the seat... once your feet are on the ground pull down the restraint, lock the seat belt, once your locked down your locked down... it operates like any other B&M basically.
Yea, the typical rider's intelligence certainly isn't high (Welcome to America!).
In addition, EACH seat must be checked by a ride operator, and then confirmed with the dispatcher. Since there is only one dispatcher that must listen to each seat confirmation, this can take more time than you think. And then if someone pulls the restraint down too much, guess what happens? They have to unlock the seat and re adjust it. Note that the person who must do this is the ride dispatcher. I think the main problem is that the main ride dispatcher who is at the "computer" has way to many things to do, and that causes part of the delays.
I mean really, by the time that the train on the brake section is in the station, the other train is well up the lift. Then it's only about a minute before they're on the brakes again. 1 minute to unload and then re-load a train with a complicated restraint system isn't easy. Typically, as I recall, we had to wait on the brake run for at least 30 seconds before we could re-enter the station.
So IMO there is NO way in hell they could run three trains smoothly, if they can hardly run two.
EDIT: Does anyone think that since some of the signs suggest the repeating of the ride (shuttle mode, or going in reverse) that this could suggest Vekoma's new outer-rail technology that features a train going forwards and backwards. This would be wicked with inversions too. Of course that does kill off that segment of track idea/picture, but since there aren't any other pieces of track lying around maybe it's true that that piece of track is just a replacement for MF.
Not saying I'm right, just trying to stir up new ideas
