Arrow spring-loaded wheels retrofit?

Saturday, January 19, 2002 2:57 PM
After riding Cyclone @ Dreamworld & Corkscrew @ Seaworld, I got to thinking & yes, this was before reading "Why're coasters rough?"

Now that TT & X have spring-loaded wheels, do you think Arrow will offer parks a retrofit (or more) for their older coasters to make them run smoother?

I'm not certain about X, but TT does not have spring loaded wheels.  It is my understanding that the wheel assemblies are identical to those found on Steel Phantom.  It woud be nice, but I don't know how those new type of assemblies would handle some of the worst transitions on the older Arrows.

I've heard that Tennessee Tornado was pretty smooth, but the two days my friends and I rode it, it was just as rough as any other Arrow I'd been on.  One thing I'm curious about though are BGW's Arrows.  Loch Ness is just as smooth as any other coaster I've been on and so was Big Bad Wolf.  I'm a little curious as to why they are so smooth.  Perhaps better maintence?

I think Arrow may feel that those other coasters are just lost causes.  Making them smoother won't matter due to the fact that they will never be as popular as the, "4 across ones with all the cool layouts."

On some Arrow coasters, it wouldn't do a whole lot. Take one like GASM or Shockwave, and it's not really the wheel assemblies that need a redesign, it's the transitions. They are too sudden for how fast the train is moving, spring loading the wheels would only make it a more graceful (instead of shuffling) slam into the MCBR, corkscrew, boomerang, or whatever element it's going in.

That's funny, I can think of a great 4-across Arrow that has a spectacular layout (not to mention wave reviews!). :) TrBiggar (and various others over the last year) are right. It's the transitions, not the wheel carriages. But I do see that shuffle on some older Arrows with smaller diameter wheels (like Dragon Mountain). If there is a space, the wheels will move until they come in contact with the rail. The newer sets like TT have 10" road wheels, I believe. The road wheel axle block sits up higher, but no change was made to the guide or upstops, so it still may shuffle if the guide wheels wear too thin. And I also notice a problem if the guides are old and have less tread on them (which is fixed with spring-loading). I would love to ride Shockwave with sprung wheels, but I doubt that would do much for it. TT's transitions are flawless, and I cannot think of a finer example of Arrow's capability. It's also important to note that BGW does not let their coasters run wild.

All Arrow coasters are designed to leave a little room between the rails and the guide wheels.  This is supposed to only be about 1/4 of an inch or so, but steel being the imperfect material it is this can fluctuate quite a bit depending on the tolerances during manufacture.  As the trains "shuffle" back and forth the guide wheels do take a beating, and it's inevitable that something starts to bend or give just enough to start widening that gap.  The better maintained the coaster is, the more the trains will keep the correct gague for the guide wheels and track, and the smoother the ride will be.

TriBeggar said it well.  I think that neither Loch Ness Monster or Big Bad Wolf have some of those nasty transitions other Arrow's are so infamous for.  I wonder if Arrow will ever retrofit their rides with lap bars.  We'll just have to wait and see.

I have never heard of a rough Suspended, IE Big Bad Wolf.  The Swinging pretty much does teh same thing a suspension woudl do.
