message: I removed this unsourced statement because it does not have a neutral point of view: "Great America fans are angered even to this day that the Great America Scenic Railway was removed for absolutely nothing."  While it is understandable that PGA fans would not like to see one of their rides leave and not be replaced, the language in the statement is too extreme.  Is there a reliable source for saying this? --Idont Havaname (Talk) 18:27, 2 October 2006 (UTC)

message: Can someone tell me the actual top speed for this coaster? There are 2 speeds listed and I dont know if either of them are right.  —Preceding unsigned comment added by 71.241.30.19 (talk) 04:46, 13 November 2010 (UTC)
replies: text: according to RCDB. Where do you see the other speed I can only see 80 in reference to this ride. Themeparkgc  Talk  07:33, 13 November 2010 (UTC)

message: I recall being at Kings Dominion (our kids would go every week - we had season passes)  and more than a dozen times I'd see people stuck at the top. 
The ride used a computer to gauge the car weight and the amount of distance it would use to brake at the end.  It would then try and calculate the next shot.
Problem was - it screwed up a lot.  Poor engineers would be there trying to figure out why it would fail and undershoot to the point of the cars not making it over the hump.
So we used to go to a restaurant near the bottom and we'd see them doing test shots with water-filled dummies.  Over and over, again and again.
Just happens that one day near closing time I was standing near one of the stanchions at the banked, horseshoe curve and noticed one of the gussets vibrating wildly -  at least a +/- 6" deflection - every time a car went by.  It would stay in this random motion for quite sometime - like multiple harmonics along it's length.  Usually until the next shot.  
So it dawned on me that the reason they were having such an issue predicting the rides overshoot at the brakes was because that random oscillation would arbitrarily add or subtract energy from the cars as they crossed over it.
As I was standing there, just so happened a structural engineer walked by that was picking up his kid.  
"I'd never let my kids ride that..." he said.  "The whole thing goes uncontrollably resonant.  Probably caused by the fact that they had to remove a section of track when they moved it from Utah and had to relocate one of the stanchions due to it interfering with an existing water run off pipe. "
So that might be why they closed it.  A lot of coaster sites say it was due to the rubber tires ... not so sure about that.  I think they got tired rescuing people from being stuck at the top.  — Preceding unsigned comment added by 71.114.86.209 (talk) 22:24, 2 July 2023 (UTC)
