I think I got it. I think I know why V2 got extra supports. Now you may have already figured this out.
Of course you have noticed the V2 sways. If it is really windy and V2 is running. When V2's brake stops V2 on its back tower. Then after a long time of V2's brake stopping V2. The of the wind would keep hitting V2 and all the pressure allowed on V2 would cause the back tower to snap.
I hope that helps. Post what you think about my theory.

Sorry about the grammer. Yes I do need to work on it. It sounded perfect when it was still in my head but when it got on the forum then it got a little confusing. I reread it and I agree it was confusing. I am sorry though.
I not worrying about it. I just thought of my theory(in the most unlikely place too) and wanted to post it.

I do believe that your theory is correct, however I feel there is more to it. Its all a matter of resonance, if you get the wind with the right frequency and a train sending the towers swaying, the waves form constructive interference and build up enough energy to do damage. Look at the Tacoma Narrows Bridge, thats what I'm talking about.
I also believe however that Wicked Twister helped to expose these flaws, without something that was on Lake Erie and its high winds the stress fractures caused by this would have gone unnoticed. When Intamin finally inspected WT, and saw what the wind was doing they reinforced WT greatly, and they began to wonder if their engineering needed a little addition to its figures.
Rather than trust its original engineering, which I still believe would have been completely safe, Intamin took the safer route and decided to stiffen the supports a bit, not too much or else you would get sudden breakage rather than gradual stress.
I'm going to be doing Engineering at Marquette, so I'll get back to you in a few years when I know whats really going on with the Engineering.

The track was designed with wind forces in mind, it's all open bars, if anything the new solid support increased the wind load on the ride, though I have explained this in relative detai in another post.
(for those not wanting to look it up, the 7+ ton train that travels up and down the spikes has alot more to do with it, especially when it's held up on the second spike and the entire spike starts to bend like a ruler being bent backwards)
