Question about Everest

[jmicro59]

Just back from a 12 day WDW magical vacation and I noticed something while I was on Everest. Just as you come out of the loading platform on both sides of the track there are two lawn sprinklers wetting down the track. Anyone know why this is done?

When the vechile brakes, there is tremendous friction on the system. The cooling is done to keep the brakes and metal pieces from overheating. The same is done to the LIM launch on California Screamin. I haven't seen what you are talking about, but this is my best guess, because of how many times Everest Stops, 4 Total, with many other Safety Brakes that can be activated, in addition to the regular "slow down" brakes.

hang on if they can put sprinklers in to spray the track to stop friction,why cant they put the mist effect back up in the mountain itself,its the same thing isnt it?.

 

[Chape19714]

maybe beacause of the sensor placement. The Sprinklers are ment to cause the track to be cooler, but the Mist is not. The Mist also is very fine, which could set it off, while the sprinklers are a steady stream. My above theory is just an educated guess, and is subject to verification.

Just a guess, but you make an excellent point.

The mist in the cavern effected the sensors more than it did the track. The computer couldn't tell where the train was located, thinking it was not where it was supposed to be, keeping it from switching the track, and causing an e-stop to prevent the train behind it from hitting it.

Hmmm, I thought the brakes were long metal strips that are mounted underneath the train. These sprinklers were only hitting the two rails of the track and didn't have enough spray to hit the under carriage where the brake assembly would be.

That goes to show that it is a good thing that the mist isn't there. I was scared enough on the ride as it is (I was fine after it was over, I had just gotten worked up about it) but it would be even worse if when we started going backwards, it went the wrong way!

That is where the brakes are, maybe they weren't turned on all the way. Maybe it was a part of the switch piece right there for the garage area. I really don't know, but the friction theory is my best guess.

The mist was affecting the mountain structure, not the ride. I'm pretty sure the sprinklers are there because the trains are going a little faster than they should be due to the heat. They put those there to cool down the wheels. That's all i've heard told.
