Rollbacks?

[sheikra_rocks]

I've seen BLSC stopped on top of the spiral before....

Train 4 on Montu in tampa rolls back between the mcbr and batwing sometimes.

there is a video of a Raptor train sitting between the mcbr and cobra roll on youtube.

I had 7 or 8 roll backs on Wicked Twister.

I should add that when Son of Beast valleys (or saddles), and it is almost always empty at the time--but not always, there is a long time for everyone to get a sickening feeling of reality, as the train goes almost to the top of the hill it didn't make it over...or even goes just a bit over it, then falls backwards and goes backwards and forwards like a pendulum or giant metronome, over and over and over until all the accumulated energy is spent. This can take many, many minutes

I love making it do that on No Limits ( )

So how do they get the train back and fix the problem after a roll-Back?

ok i feel stupid asking this but what does valleyed mean

[Beast1979]

ok i feel stupid asking this but what does valleyed mean

It goes through a dip, but doesn't make it up the next hill, and Valleys inside the dip.

o ok thanks

As for saddle...look at what a saddle looks like...a valley between two hills...some say a ride valleys, other say it saddles. I guess it depends on whether you were raised on or nearer ranches or farms!

Footers or Footings?

[The Interpreter]

Footers....footings? RUN FOR THE HILLS!

isn't that the ride on a normal day?

[The Interpreter]

And then the darn thing rolls back, and they make me get off and go around again if I want to ride it again!

[Beast1979]

Amen! Sweet Thrills that ride gives. The one Ride where rollbacks are good!

[FOFreak]

Has there ever been any rollbacks on Invertigo?

[firehawkboy]

^Yeah. I've seen Invertigo go up the 2nd hill and it failed to latch on to the catch car. But the brakes caught it, and catch car came down.

[BavarianBeatle]

Well I'm typing on the blackberry from Sandusky tonight. No rollbacks this evening that I saw. But very cold and crowded. Almost three hours to do Magnum and Gemini!!! Then we came back and watched the end of the Ohio State game. But we will be there again tomorrow for ERT. .

IJST and FOF have rolled back before, SOB, Face/off and Beast have valleyed before.

Where would Beast valley? The only place I could think of would be anywhere between the second tunnel and the second lift. The second time through the helix seems possible, but just slightly.

[MarketingExpress]

I wish the ride ops. could some how make there be a roll back, i would beg them to let it have a roll back almost everytime!

When roll backs occur, it is not good for the computer system. Unless a ride op has figured out a loophole in the system, they can't cause a rollback on purpose unless they somehow close the brakes through the launch area while the train is traveling through it. But 99.9% of the time, it is random.

On Flight of Fear there is a glitch and you can about the launch but other then that they do not have any access to close brakes when they please. Only to release them when a train is in the position. Example would be to bring a stopped train into the station. The control panels are very easy to operate and is foolprof in a sense.

Yes you can abort the launch on FOF. But ride ops can also stop the train in the brakes by E-stopping the ride if they need to, which is what I was referring to in my origional post. I am very familiar with the control panels and know how these rides operate.

You can stop the launch brakes without the e-stop, but even if you did use the e-stop maintenance would have to reset it. So it would be pointless to hit it. (unless a real emergency of course). Trust me I know how they work too i work FOF lol

Just to chime in on the TTD and KK issue. The hydraulic motors and fluid are warmed by electric warmers and cooled during use with a heat exchanger (better known as a radiator) to a pre determined temp. The two things that need to be worked in the mornings are wheel bearings and the cable. The cable does not have to be stretched, just warmed up so the individual strands in the cable bend on to the spool. And at speeds of 100+ the wheel bearings do not take long to warm up. The cable is the most important. At first TTD was storing the cable wrapped around the spool, the cable did not like that at all and did not warm up or wear properly. Last, the operator can not ask for less than the absolute minimum to propel the train over the crest, they can ask for more with a dial if they have one particular train that is having a bad wheel day. The minimum and maximum is preset by the engineers, and the operators are told to use the minimum unless a situation arises. A lot of the time when a train does not make it over, it is because the motor did not have enough energy stored to perform the task. That is caused by fast load and dispatch times, and the system did not have an adequate time to charge. This info is based on KK operations, and I am assuming that info I received about TTD is correct, so don't shoot me if I am a little off.

See I learn something new all the time. I didn't know about the hydraulic fluid warmers. Now are those something that came after the issues with TTD in the begining and were new for KK or did TTD have those in the begining. I only ask because this is the first I have heard of them.

If you watch the radar reading of speed on TTD, after a roll back you can tell they dial it up because it usually launches 5 to 10 mph faster. Just overall a great ride to sit and watch.

I've never noticed the radar on TTD. Where is that?

During a morning test Beast didnt make it up the last hill from the helix into the brake run. It would have valleyed if not for the anti-rollbacks that are placed on that hill. so it was a 90% valley i guess. But to fix that situation the train had to be manually pushed up the rest of the hill were it was stuck till gravity took hold when it caught the brakes.

[Jasper]

Wow it must have took some man power to push the train back up the hill. Sounds like a cool experience.

Fluid case heaters are pretty much standard on equipment like this. I did NOT work on TTD, so I can not tell you for sure if they were there from the beginning. The wear and tear on the equipment would be tremendous to send cold fluid through a system like that. Like I said though, the warm up is to warm up the cable for flexibility and the wheels on the trains. They "Dial it up" to save wear and tear on the equipment, normally it will run at about 80% giving them 20% to play with. (20% is actually a lot of power). At warm up (in the morning) they will run it at about 50% and work up to 80% in a short time. Once again, I can only go by what I have been told about TTD, but KK I am pretty sure that is how they still perform warm up. You were pretty much on the right track, I just wanted to add my......well......now it is worthless, but it used to be two cents. Hydraulics are a great source of power, but MUST operate at a specified temp, too cold or too hot will cause a failure.

[RailRider]

The radar located on the sign on the engine room/cable building. This is a great shot of it from the grandstand thanks to coaster image.

Monroe, once again thanks for the education.

[clbehymer]

^Thanks! As many times that I have been to the Point and ridden TTD, I have never seen that. I guess I'll be looking for that the next time I go up there.

so do they really just push and pull on train or do they hook it to a wench?
