Thorpe Park | Hyperia | Mack Hyper Coaster | 2024

This isn’t normal for a coaster of this magnitude to have this many issues.

I don’t think this is Thorpes fault I think Mack have sold them a dud.

What we thought were teething problems clearly aren’t and this coaster has lift hill & valleying issues which haven’t been solved in the off season.
 
A few big things that need addressing in this thread.

I'm starting to think that Mack may need to add some kind of rolling launch on that section before the outer-banked element to prevent this happening again.
This is something I see thrown about a lot now, but it's not a simple thing to do.

The ride is a standard lift hill coaster. Adding on LSMs to the track and making the train capable of utilising it is not a quick or easy thing to do. In fact, I can't think of any coasters out there with a chain lift hill and LSMs. There's likely a reason for that.


The design flaw that the third element is taller than the second element would do that.
This isn't a design flaw, this is the design.

The ride was purposefully designed like that to help create the hangtime/stall feeling. There are plenty of rides which have a latter element taller than a previous element.

The issue seems to come that Mack have done some sort of miscalculation. It runs absolutely fine when filled with people, but then struggles when empty. Which I'll discuss in a bit.


Have they not learnt that this thing needs to test with dummies?
They do. Every day. The testing process includes a full train of full water dummies, which are gradually emptied. It takes a long time.

But ultimately, a coaster has to be capable of running empty. It just has to. They could, if they wanted, test the ride with dummies after every shutdown. But empty water dummies are heavy, take a long time to load/unload. And it'll take even longer if they fill and empty those.


As mentioned, I think the issue is Mack have done some sort of miscalculation somewhere. The ride runs fine when full. But when empty, in certain conditions, it seems to absolutely hate the stall. That miscalculation could be anything, to do with what the climate conditions are like in that part of the park, the direction of the wind, etc.

Obviously that's a huge thing to say: I'm saying that one of the biggest coaster manufacturers around has made a pretty large error. I could be well wrong. But it seems justifiable given what we've seen. And also, let's not forget this relates to a never-before-done element, which is designed to mimick the sensation of stalling. They've pushed the envelope quite far out, and maybe they've just gone too far out. I'm not saying that's an excuse, but I'm not saying it's a big blame game.
And again, I could be completely wrong with what I'm saying there and there might be another reason.

But now, what happens here. Do the park continue to just run it and hope and pray rollbacks don't happen? Do they look at redesigned trains, given it's now rolled back on various different types of wheel? Do they have to redesign and rebuild that element? Do they have to convert the lift hill and add LSM recovery to that area? Can they actually do anything? And if they do do something, who foots the bill? Some coaster manufacturer legal issues I'm sure very few of us have any ideas on.
 
How long is it typically closed for when it valleys?
The first time it happened, it was on the 19th June and it was back open on one train on the 22nd June, then the last time as mentioned above it valleyed on the 2nd October, and it was back open for the Fright Nights’ press night on Thursday 3rd October, then to the general public the next day for the first Fright Nights (4th October).

Looking back through this topic the first time it happened the second train was back running quite quickly on the 23rd June, whereas it took till Saturday 12th October for the second train to return.

I’ve had it confirmed from a friend who took a picture of the train that ended up valleying, that this time it was train 2 that valleyed for it’s first time, following an operational running close down due to high winds to get the guests off train 1.

I feel like it would have been more logical considering train 1 has previously valleyed, both times with dummies in morning testing for the park to have preformed an evac on the train in the break run instead of running the risk sending the empty train, but that’s where hindsight comes into play.

I can't think of any coasters out there with a chain lift hill and LSMs. There's likely a reason for that.
Takabisha, and its clone TMNT ShellRaiser Are the only two that come to mind for that, but they were designed to use both.

I was thinking about taking a day off work and heading over to the park this week because I *still* haven't had a chance to ride - despite Thorpe being literally a 30 minute drive away - due to all the engineering issues last year (it was down every single time I visited). I'd glad I didn't bother booking leave. Such a shame that it seems to be so unreliable.
I've not ridden it either and it's like £200+ with trains, tickets and overnight stay, so its persistent unreliability is too stressful

It’s an unprecedented situation, i’ve not known this happen to a coaster this regularly other than a launch coaster with a top hat which is obviously designed with rollbacks in mind.

How long before it’s a cold day, the winds blowing in a certain direction and it valleys with people on board? Definitely a possibility it could happen one day.

Also I thought they were just hauling the empty trains up the lift hill at higher speed to make sure it didn’t valley? What happened to that.

It stopped at the beginning of the lift hill just before so maybe the lift didn't make it upto speed in time
 
I haven't seen or heard of the "Boost Mode" being used this year.

That was a quick fix scenario in any case, and never seemed like a suitable long-term solution, so maybe it was just a "get it to the end of the season" thing.
 
I do feel sorry for Thorpe. They finally invest in an excellent coaster that everyone loves, only for it to be plagued with problems, seemingly due to the manufacturer's miscalculations.

So what are the possible long-term solutions?

Could something be added to the top of the outer bank, to help propel it over when it's at risk of stalling?

Could they add a sliding transfer track to the bottom of the valley, for ease of train removal when it stalls?

Could they re-design the trains to make them heavier?

I'm no ride engineer. But it'd be interesting to get the opinion of someone who is, and how they would solve this long-term.

Not a good sign. I've still not had a chance to get down to Thorpe to ride Hyperia. I'm desperate to, but with no annual pass and a 7 hour round trip in the car I'm too scared to make the trip and the financial cost to not get on it.

It's easy. Just build a pole with a rope attached that riders can grab onto and pull themselves round if it slows down. Doesn't help when the train is empty. Maybe move one of the hand dryers from the toilets and attach it under the track?
 
Mack did install drive tires on RtH after it stalled on the top hat. So it's not a totally crazy rumour to believe 😅 However, I think those are just used to help recovery and aren't actually used as boosters (as far as I know).

It seems like the outerbank requires a slim margin on speed to keep forces reasonable while also not valleying. When I rode last year, there was a surprising amount of variation between the two trains. Both trains were fully loaded and had been running all day, however, one crawled through the outerbank while the other zipped right through. Apparently the trims added to Stardust Racers were to prevent excessive forces on riders, so it does seem like Mack might be a little *too* daring with their designs lately.

Vekoma did lower some elements on Odyssey at Fantasy Island because it kept valleying. So redesigning the outerbank isn't completely unprecedented...

Oh crap, I fell for Thorpe Pork... Of all the dumb things.

Edit: wait, I'd blocked them before? Sigh...
To be fair, that is a missed opportunity for a BBQ restaurant in the park!

If it were me, which it's not and I've had a drink or two, I'd just ramp the chain speed up 10mph and just ****ing yeet it round the outerbank. Works for RMC...

More drunk Hixee is exactly what the world needs.

This is a fantastic idea (yeeting it around, not the drinking, although that's not a bad idea either.)

HOWEVER, looking at that video, I'd properly love to experience a stall on that element!!!
