I seriously doubt they will put mid-course brakes on *KOCK ON WOOD*. They probably just adjust their dispatch times, cause they dont have to worry that much about midcourse brakes, if you think about it, one train (at least) will be running the course or going up the hill, another in the loading station, and possibly one at the end of the course or in the brakes or unloading station, and if they had a problem in the loading station, they can keep one train in the un-loading station, and another in the brakes at the end of the ride, so...BOOM! There is a 3rd block technicly. That might be what they had in mind all along, no midcourse trims so they use separate stations to add another block and increase the amount of people the ride can handle.
