As you can see, Top Thrill Dragster's entire vertical column is completely supported, unlike its sister ride at Knott's. I doubt moderate to slightly high winds should cause for it to close down. As for riding in the rain, Superman The Escape and Dodonpa have similar stories. Ask for those.
The only problem I can see with wind and TTD is that if the wind is blowing too strong in the wrong direction, is there a potential that a train may not make it over the top because of the high air resistance?
I would pray for a rollback, not only would you get to go BACKWARDS down a 400 foot drop, but you get another launch without having to wait! ------------------ If you haven't rode Raging Bull in the back row you haven't lived. The feeling on that first drop cannot be explained in words!
The train is unloaded, and the passengers of the cycle that "short-shot" are to wait on the exit ramp while they send off for a few test runs before letting them on again. That's what they do with Xcelerator. The electromagnetic LIM/LSM rides don't follow the same path as these Hydraulic coasters. They need to investigate what was the cause of the short-shot.
Of course it wont operate in the rain no roller coaster at Cedar Point runs in any rain. This is because Lake Erie tends to turn the smallest rain storm into a thunderstorm with no warning on a regular basis. As with the high winds (moderate wind should hopefully not be a problem), this park is located in Ohio high wind does not usually occur without a storm so I dont see it being too much of a problem.
------------------ I don't care what anyone says, Magnum is better then Millenium Force.
Wind, unless gusting over 40 mph or so, wouldn't increase wind resistance very much I suppose. In Physics, they told us that Wind Resistance is just the mass of the object falling creating friction with the still air as it falls, so I wouldn't think that wind would change that, but I may be wrong.
------------------ "Enjoy your record-breaking ride on Millennium Force"
The trains wont collide if it rolls back. They have brakes on the launch strip which close when the train passes, and doesnt open till the next train is dispatched. That way the brakes will stop it on the launch strip. Wind is just added friction if you think about it.
High wind could make a difference, look at Windjammer, although I guess that was a bad design though. ------------------ So you believe that you are studying us, then kindly explain why you are the ones trapped in your seats.
