Is it just me, or is this inline twist different from other inline twists on Intamin Inverted coasters, like Volcano? I've been on Volcano, and I think that the inline twists on it are more like B&M inverted zero-g rolls, but this looks like one of the zero-g rolls on B&M sit-downs or floorlesses, giving more of a zero-g feeling. Is this one different or is it just a tricky camera angle?
Intamin makes thier rolls like that. The rails when upside down are lower then were you are right-side up. It lines your heart up through the roll. Very nice... ----------------- www.SFWoA.com Your Connection to SFWoA!
They pretty much look like the same barrel rolls to me. Personally, I think that Intamin's barrel rolls look the best. Just think about 5 of those right in a row for Atlantis, the new coaster with 10 inversions.

Hmm... I guess I never paid it much attention and this picture was so dramatic... I thought that the rolls on Volcano were slightly heartline, but not as heartline as this. I'll guess I'll have to pay better attention next time I visit!
I've been on this coaster, and those inline twists give you some hang-time. The Lethal Weapon Pursuit (WBMW) has also got the same type of barrel roll. There is another Intamin inverted in Spain, look at the difference in the support structure of the loops, Tornado (in Spain),Tornado (in Finland). I wonder why there is such a big difference in the supports, could be the fact that in Finland, there is track going through the loop? *** This post was edited by Kari on 9/28/2001. ***

The Spanish coaster uses three-rail track, which is not as rigid as the four-rail track, so it is connected to the support structure what appears to be seven times (hard to see in the photo). On the other hand, the more rigid four-rail track used on the one in Finland needs support only on each side and at the bottom of the loop.
You can see similar points of contact on the Intamin hyper coasters. Millennium Force has two-rail track in the brakes and station, where supports are every few feet. With the three-rail track, they're further apart. Then the four-rail track spans large distances between supports, over the lagoon, for example.

The only Intamin inverted full-circuit I've ridden is Volcano (probably true for most of us US buzzers). I'd love to try a few others, but would like for Intamin to explore other types of inversions, and add HELICES.... ----------------- rollergator - intent on improving the "guest experience" - coming soon to a park near you
It is true that B&M's do go upwards, but the actual inversion is pretty much in a straight line. They are designed so your heartline travels in a parabola or the way that you would naturally travel if the inversion was not there. Intamin basically does the same thing, except they place the inversion in a straight piece of track. In order for your heartline to stay in the natural motion of the train, the track has to be lower when the train is inverted. Simple Physics......
