The last hurrah for deja....?

I just derived the fact that a new computer system or reprogramming of the computer system would prevent almost 99% of the valleys. I am not a rollercoaster designer, No one on Coasterbuzz is but I just derived that from common sense. I have no first hand experiance and its just an oppinion.

My understanding has been that the Deja-Vu triplets valley because there's some mechanical failure in engaging the second lift cable (why they'd use a cable instead of a chain, who knows).

As much as we wish it were true, you can't correct for mechanical defficiencies is software. "We'll fix it in software," is often not the best mindset. This is a mechanical problem that requires a mechanical fix.

The mechanical failure is *why* the train may prematurely drop from the lift, but there are systems in place to prevent the train from valleying between the loop and the cobra roll (ie a set of brakes going halfway up the loop that do not open until the train has reached a safe height on lift two). Obviously, since SFGAm's has valleyed in the place it never should *twice*, there's some other problem and perhaps a stricter computer system wouldn't hurt.

...or they could fix the *real* problem instead of patching the rest of the holes that are its result.

What is the "real" problem?

No matter how hard you try, you can't depend on a machine to hold onto a train that heavy (and it makes it even more difficult when that train has to be caught mid-air). Therefore, a system needs to be in place to prevent the train from valleying in the said place. Boomerangs have had this system since they first opened. So, if the system needs to be in place and it *doesn't* work, then you tell me what the "real" problem is.

It's rare that trains let loose early from the lift, but it happens. When the other system has failed *twice* out of all the rare times when it does let loose, which system isn't working?? It's not hard to see. One system works almost all of the time. The other has a pretty poor record.

I though the Vu's were down because they were reconfiguring the train situation, making them completely four across instead of the staggered four across?

There are much more complex mechanical systems that operate on a daily basis with much greater reliability than Deja Vu's cable system. Heck, your car is probably more complex than Deja Vu's cable system. Don't even start on stuff like airplanes or factories.

Okay, but what I was saying was that those systems all have *backups* in place. You can't depend on a machine without having a backup...or at least you can, but not wisely. That said, Deja Vu's mid-air clam is still awfully advanced, and understandably has some downtime. However, it's not much. Most of the problems (common, minor breakdowns) have nothing at all to do with the lifts. I think you severely overstate how many problems Deja Vu actually has with the lift system itself, especially if you compare it to other rides that are having problems (Intamin's rocket coasters, for example).

We have enough DV topics going on. Until some reliable news comes our way, we will not depend on rumors from other coaster sites.

Closing.
