Mantis stuck

Wednesday, May 21, 2003 7:21 PM
I was at Cedar Point on May 9th and I was heading to Mantis when I saw that it was stuck between turnaround to the midcourse brakes and the midcourse brakes. The employes were pulling the train with a rope back and forth to get it up the midcourse brakes. Has this ever happened before?

From what I have heard, Mantis does this alot because the trains are a little heavier than most coasters.

What makes Mantis an exception? The Georgia Scorcher, Chang, The Riddler's Revenge have the same trains as Mantis.

I was wondering when I'll hear something like this cause I wanted to know how they get the coasters back running when they stall.

They take them off the track and put em back on in the appropriate spot (train shed, etc.) Big job!

Mantis was a rare coaster that didn't valley in it's first year of operation...in fact I beleive the first time it stalled was only two or three years ago.

Heavy dew in the morning can slow down a steel coaster. Its like the way you feel your car slow when you hit standing water on a highway at high speeds. The wheels have to squeegee off the water and that takes energy away from the train. Also, in the morning, the wheel bearings are cold and the grease is stiff. This also slows the train. The trains actually weigh less in the morning because they are not full of guests. A heavier train will do better and parks do add weight in the morning.

Also, the wind direction has a lot to do with it. Mantis can be slowed down considerably if the wind is blowing at it head first on that brake run. Of course the same thing can be said for just about all their coasters. If there's a strong wind off the bay (like there was on the 11th) Raptor will be shut down, and when it's 60mph like it was that day, so will MF (and apparently MS, MR, Gemini, & MXL200).

Actually, as far as I know, this would be only the second time it has ever happened (at least where the public could see it). The first time was the year before last at the bottom of the first drop.

What a mess. When it got stuck at the bottom of the first drop, what exactly did they do?

Man, what a shame. This has to be in part due to that darn trim on the drop. When Mantis first opened, it was one nasty white knuckle ride. You could feel some tightness in your legs after riding. This sucker was furious. Then, they added the trim on the first drop. Just hasn't been the same since. Ah, the memories...

What is going on with CP? I know they just opened but I've never heard of this many problems hitting them at once. All I've heard about so far this year are the constant break downs with TTD (which is expected), rollbacks with TTD, constant breakdowns with MF, breakdowns with Raptor, and now this. I'm going in early June. Hopefully luck will be on my side. I've followed the park for years and I've never heard of these kinds of problems happening so frequently in the opening weeks.

Nothing is happening. Have you ever looked at what happens during the first few weeks of park operations in parks that close for months? These coastes have been sitting dormant sine the end of october, of course things like this are going to happen.

Cp can't prevent rollbacks; they just happen.

But how do they stop the train when it vallys? I mean doesn't the train go back and forth when it stalls? How do they stop it?

Eventually it succumbs to friction. You can see the same effect with a pendulum. Start it swinging, and then don't touch it again. Each "swing" will be a little bit lower, until eventually it stops moving.

How did they get the train out between the first drop and the loop?

I was under the impression that the trim hasn't been used since Mantis went to two trains.

Really? I was not aware of that. Then again, the last time I made it to CP was 2000.
