Jurassic World VelociCoaster Construction Thread (Opening June 10)

Uhh, in this photo, it looks like they're installing LSMs on the top hat? What? Could these be used as trims/to reduce speed?

Trims. Man, I was hoping it would be untrimmed.

I would rather it be trimmed at the top tbh

As I suspected, they're ensuring the drop is taken at a certain speed for the second half

It's odd that they're using LSMs and not brakes, could be because retractable brakes wouldn't fit right on that track style. That paired with the fact that there's only 3 makes me think that they don't plan on taking much speed off of it.

Could fins be used to also push a train down if there was a stall? Like manually triggered to dislodge a stalled train? Serious question, I literally don’t know. Maybe these could serve dual purpose then, in addition to the normal trimming.

Yeah, I imagine Universal doesn't want rollbacks

Could be that as well. What Vekoma does is they launch faster than it was designed to, then they trim to the desired speed. I wonder if this is a new method to prevent rollbacks by launching at the desired speed and pulling it over the top if it's not fast enough.

Yeah, this ain't Walmart.

 

[WillQ92]

Maybe the last thing we see before loading is a nice view into the paddock?

 

[Nico]

How close to the current construction wall pattern do we think the new fences will be?

In that location, 3 trims could make a huge difference.

Any insight as to why this curvy tunnel thing is built so substantially? A dictator could shelter in that thing!

Since it appears it will give off the impression of being a transport corridor, it has to look bulky enough so the dinos couldn't escape?

No company really uses pinch brakes for trims anymore. it could work like below:

its controlled and gives you a slight hanging feeling.

No. In a worsts cast scenario you would get a roll back, the launch resets and goes for it again. Generally these are static, while traditional LSM can slow and speed up.

Yeah, I imagine Universal doesn't want rollbacks

Rollbacks are going to happen. Universal has no control over it. It's par for the course. It has nothing to do with it being a coaster at Universal. Even Hagrids has had rollbacks.

 

[GAcoaster]

It's an easy way to minimize rollbacks while still regulating speed. You launch faster than necessary so you know it will make it over the top, then reduce the speed slightly to insure that the riders aren't going to get whiplash on the rest of the course.

 

[jarmor]

You don't "launch faster than needed". All launch systems are created to launch within a particular speed range. It will never be the same speed each time, it's more of an average speed. Sometimes it may glitch and cause a rollback. This is why coasters weigh the train to see how much power it needs to launch it. I know when Carowinds was programing Copperhead Strike, they tested the launch at various weights of the train so it can be calculated what power would be needed when the train is empty vs half full vs full.

 

[gabe3235]

Intamin doesn't use pinch brakes period. They have I think two or three early rides that had them and haven't used any on their launch coasters. They have retractable brakes, fixed brakes, LSMs, ad drive tires. Trims are generally fixed or retractable on Intamins, but this track style doesn't have the space for retractable ones.

Yes, but there are always variables like weather and the wheels/bearings-- that's why every launched coaster has rolled back at some point. When Intamin built Kingda Ka they oversped the launch and added brake fins to the top which is why Kingda Ka seldom rolls back where TTD does fairly regularly in comparison. Easier to give the train some extra speed to make up for wind and cold and other factors that could slow the train down. Yes, weight can be calculated and compensated in a launch, but other variables still come into play.

Well yeah, but they want to minimize it

Every time it happens in front of guests it will blow up on social media and end up on the news because people are dumb

If they can attempt to eliminate the amount of times it occurs they will

 

[Scott W.]

Are rollbacks even a concern for this coaster?

The top hat isn't that tall in comparison to other coasters and I'm not sure if weather will play a big deal since it's launching inside a tunnel.

The trim brakes are no doubt for the track after.

Rollbacks are a concern for any launched coaster, for example, Hagrid "rolled back" during the opening week when it didn't make the second launch that goes past the queue.

As others said all launches weight the vehicle first then adjust the launch speed to make it over the hill. Sometimes there's a miscalculation or some sort of weather change (rain or wind) that affects the train and causes a rollback. Both launches on this ride will have breaks that slow down the vehicle if it doesn't make it over the hill and allow the vehicle to attempt another launch.

This “they want to minimize rollbacks” talk is the funniest thing I’ve heard y’all come up with in a long time. Listen to @jarmor on this one, he’s got the facts.
