Blackpool Pleasure Beach | Icon | Mack Multi-Launch

Hmm...

Looks quite different.

On a random note, Icon apparently wasn't open as of 1pm today due to some sort of technical problems, in case anyone was thinking of visiting later today.
 
I hope this doesn't become a pattern from the Pleasure Beach. Tbf it didn't have any issues opening day, apart from someone throwing up so the crew had to stop running the ride for 10 minutes so they could clean it.

You forgot about the rain

So after reading all the reviews I need to be in the left hand side of the train, at the back, the weather needs to be above 20 degrees and it has to be after 3pm. Got it.

It does rattle, but it's far from rough. Just a slight vibration that most coasters in the world have. I'm really not sure what people are complaining about tbh.

Is it like how Mako and The Swarm apparently have rattles according to some people, but they are two of the smoothest coasters I've ever ridden? There are probably smoother rides out there, but these two felt smooth as butter to me, and I'm sure Icon will too.
 
Probably be shot down quickly and corrected, but is this slightly rattle actually part of the design?

Like, surely there's a tolerance of so many millimetres built in to allow for expansion of the track in hotter weather, or to cover the differing weight of the train? So whereas a fully loaded train at the end of the day may have a different direct route throughout the track than an empty train in the morning, and there's a tolerance built in to counteract that? Could that explain the slight rattle?

Or am I, as often the case, talking ****?

I think that makes sense in my head.
 
It does make sense. I saw a TPR video of a back row ride on intimadtor 305 with empty trains. The rattle is clearly visable , but if you watch a video of a full train ride you can't see it.

I think most coasters have a bit of expansion room. It's most noteable on old Vekomas - look at something like Infusion when it's in the station and you'll notice that there's a visible gap between the upstop wheels and the track. If I remember rightly, I'm sure I read somewhere that the likes of B&M used some sort of sprung wheel assembly to push the wheels against the track, providing a smoother ride. I've no idea if Mack do something similar. I'd have thought so, given how well they ride.

Regardless, most Macks have a bit of noticeable vibration. Helix certainly does. It's nothing to be concerned about, as it doesn't really affect the ride at all. It's no worse than something like Nemesis is these days, and from what we've seen with the other Mack rides, it's not something that appears to get worse with time.
 
I remember having one ride on helix at like 10pm when it was flying round the track but had a weird rattling noise. It wasn’t so much a vibration but more the sound of a broken piece of metal / lose bolt. It didn’t make the ride rough but was rather unsettling thinking your seat was going to fly off! No idea if this is what’s being discussed.
 
There's no gap for expansion on Icon - on pretty much all large modern steel coasters the upstop wheels are spring loaded against the rail so that they are always in contact. On older ones like Vekoma SLCs and Mk1200s there are no springs but a small gap instead which does lead to the bumpy ride.

But the vibration on Icon must be caused by something else, I'm off to experience it for myself tomorrow :)

Edit (because I know the spring-loading of upstop wheels is so fascinating...): here you can see the pivot of the upstop wheel assembly (circled) and the approximate position of the spring (zig zag) that causes the wheels to grip the track with no gap.
