TTD Anti-Rollback wheels

I remember there being a topic a while back that stated TTD had anti-rollback wheels installed to prevent rollbacks by boosting the train over the crest. I contacted CP about a month ago and just got the response today, it basically said there is no such thing. Im not sure if people were still wondering or not.

Can someone please explain how anti-rollback brakes would work? haha

They won't PERIOD!

I think we determined the first time that this wasn't going to happen. Despite evidence from a friend's sister's neighbor's dog's breeder's nephew that supposedly saw the plans to add it.

This is great and made my day. Anti-rollback wheels... LOL...

I am surprised they replied back though on that. Shows customer service it making strides on answering questions.

Maybe you may have been confused with No-Limits software. I believe their version of TTD style coaster had a chain towards the top that would pull the train up if it could not reach proper acceleration. However, this was just on the game.

^An earlier topic had people arguing over the issue, so i decided to contact the people who would know. It sounded like a farfetched idea, but it doesn't hurt to ask. I'm throwing this out there to people who were still wondering.

They should just put jet packs on the back of the trains so they go 300 mph like real drag racing cars.

Or just let it roll back like it's been doing since 2003. There's no damage done by letting it roll back, other than slowing down the line while they fix the bug.

^And it gives enthusiasts a "brass ring" to try and attain every time they go to the Point.

^^Who's to say there's always a "problem" behind it?:)

Most if not all of the time it's either weather related or just the system warming up. And they handle the relaunch procedures really well now. On the days they know it's gonna have a hard time warming up, they only send out one train to launch at a time. That way they don't have to pull back all the trains in the station and unload manually so the train in prelaunch can be brought back into the station allowing the rollback train to be brought into prelaunch in order to reset the launch. Of course you'll only see this done mostly in May and October.....or just cold mornings in general.

HAHA! Seriously? This made me laugh.

^ CP Rush did not make a joke.

It does not require a full working knowledge of roller coasters to join this website.
I am willing to bet that the majority of the PB's population are working class heroes. Such as myself. And I thought that this topic was informative. Because it told me something that I too was wanting to know.

CP rush typed “wheels”, not “brakes”.

Thank you CP rush for posting this and letting me know. I was afraid that My buddy and I would never be able to get a rollback on Dragster. Our previous attempts at such have came close but unsuccessful. Maybe this year will bring one and I hope to run into you at the point.

Peace, Mikey

My understanding is that Kingda Ka has an advancing wheel on the top of the tower to make sure that it can't top-stall the way that Dragster has more than once.

Dragster doesn't have anything of the sort.

--Dave Althoff, Jr.

Kingda Ka doesn't have a wheel on top to help it over but has the opposite. Kingda Ka launches at a higher speed than is required to make it over the hill and therefore has breaks on the top of the hill to slow it down before it continues down the other side. This is why Kingda Ka has a lot fewer rollbacks that Top Thrill Dragster.

Just saw a video on YouTube. It showed the top of the hill on Kingda Ka. There was not an advancing wheel, however there were what looked like magnetic brakes that are used on TTD's brake run at the end.

***EDIT*** realmadrid kinda beat me to it.

Why don't we organize a PB TTD ride, where we all know how to slow the train down (aka arms to the side of the trains with some sort of long sleeve clothing that creates drag, palms open facing the direction you are going) and we get on the train and just get rollbacks constantly.

Maybe stick the heaviest couples in the back of the train also with the lightest up front.......

I wish this would actually work. But we would actually have a better chance if we asked them to send two empty trains before ours and then just ride the ride like we normally do.

As I understand it. Each time a train is sent a computer tracks how long it takes to make it over the top and then computes how fast it needs to send the next one based on that. So, if we sent two empty trains that both make it to the top really quick it will slow down the launch on the next one.

It's my understanding that the brake on top of Kingda Ka is so that people hang a little bit longer at the top so they can "enjoy the view." The faster launch speed has nothing to do with it. It needs that extra speed to get up the extra 30+ feet of track, and it probably crests the top around the same speed as TTD.

That may not have been its intended use, but it eliminates the need for the slower launches. Eliminating the slow cresting that is wanted on Top Thrill Dragster.

So they can launch the trains fast enough to eliminate rollbacks, while still getting the same slow cresting.

^That's pretty much it. But there's more to why. Another reason they WANT the trains to crest the top at a target speed is due to the amount of blocks. I don't know the exact explanation, but the jist of it is that they can't have trains going over the top hat at more than 15-18mph(or somewhere in that range). Anything more and a train can overshoot block sections which would cause problems.

Ka is more lenient with this because it has less block sections than Dragster and hardly runs all 4 trains in full block mode. This also allows them to "open" the hydraulic motor more which gives them their high speed launches. And the fins at the top help trains that fly over the top (which most do) slow to a more reasonable speed when they enter the brake run so they don't overshoot anything. Of course they wouldn't market the brakes in that way, so instead they market them there for the reason of giving the riders an extended time to look around......which from what I've heard is hardly noticeable when riding.
