Maverick Testing

I remember Kinzel telling that story, but I don't remember where.

^The Coasterbuzz Podcast #7!

If asking about what coasters have stalled half way through the course. I've heard of almost every coaster at CP valleying at least once over the years. TTD is obvious and WT would be quite scary if it didn't valley.

Rob - The sections that are PURE braking sections (hill over swan pond, end of ride, right before tunnel) would most likely just use magnetic brakes like on MF or TTD.

MF uses friction brakes mounted on the side of the trian. The only coaster at CP that uses non friction brakes is TTD. Mavrick will be the second.

From looking at the animation, it looks like the hill after the launch would be high enough to allow the train to finish the circuit if it clears.

MF, WT, and TTD all use non friction brakes. MF's brakes are just placed on the side of the train instead of the bottom.

You make a good point, I think you may be right about that hill being the tallest on the second half. *** Edited 9/10/2006 7:08:53 AM UTC by Gomez***

I was on Patriot yesterday and noticed it uses a combination of LSM's and friction braking. I don't remember seeing any kind of friction braking on TTD, and unfortunately, MF was out of service when I was at the park back in May. What do they use as a backup system in case of power failure?

Obviously WT isn't a problem since it will eventually come to a stop with no worries of hitting anything.

cptroublemaker: MF has no friction brakes; they are magnetic.

dr_olds: The magnetic brakes don't require power. They are permanent magnets.

Patriot at World's of Fun? I highly doubt there's an LSM anything on that ride. Its B&M, so I'm guessing its friction braking.

Then again, I forgot that Raptor has a launch halfway through, so maybe Patriot does too. LOL!! :)

^Raptor has a launch?

ha ha!! It was a joke. Leslie said in one of these threads that she loved the launch halfway through Raptor.

If these aren't LSM's then what are they?

Bottom pics. Sorry, couldn't get these to link individually. There are friction breaks right after these that aren't pictured in these photographs.

The brakes on Patriot are a combination of magnetic brakes (like those on MF and Dragster) and standard friction brakes.

They're standard magnetic brakes like on M Force and Dragster. Any recent Intamin, really. B&M started using mags a few years ago for speed reduction.

WOW - I had no idea Patriot used magnetic braking. Those aren't LSMs, but they do look like the brakes on MF. That surprises me because I didn't realize B&M was using brakes like that. Intamin owns the patent on magnetic braking for a roller coaster, right? So, B&M would have to pay Intamin to use that technology? Someone enlighten me please. :)

So if magnetic brakes don't require power, how do they adjust for train speed? Patriot must use the friction brakes actual bring the train to a stop and release it. How does this work on TTD and MF? I'm guessing Dragster meters speed by dropping the fin plates. But on side mounts such as MF, what do they use to release and control the train speed (especially mid course blocking areas)?

I definitely like the magnetic brakes, I hope they start retrofitting some of the older coasters with them.

Well to control Top Thrill Dragster the brakes go down, watch the end of the brake run next time you ride.

Millennium Force is another matter, but I don't think those are designed to stop the train, they are to slow it down. After that the tire prepulsion does the rest.

So I see I was confusing magnetic brakes with LSM's. So, my next question still relates to loss of power. If Maverick is climbing the lift hill, what prevents it from sliding back to the station in the event power is lost? I'm guessing many of these rides have backup power (aka UPS type systems). Would Maverick depend on backup power, or is there something mechanical to stop it?

I'm guessing TTD defaults to an up position in the case of power failure. Not sure how these LIM's would work.

The final brakes on MF also move out of the way. The section closest to the lake right before the unload station pivot out of the way as the train moves into the station.

I could be wrong, but I don't think magnetic brakes can 100% stop a train. I think they just slow it down to almost a stop. The real advantage to them is you can send a train into a magnetic brake run at HIGH speeds, slow it down quickly without causing pain to the guests, and there's no parts to replace like brake pads.

Yeah, I'm betting if train actually was stopped with a stationary magnetic brake, it would be very difficult to move it. Much like trying to open a door which uses a magnetic lock.

So, power outages, any ideas? Notice there isn't an exit staircase on this ride, so they aren't planning on this ride getting stuck on the lift hill. There's no exit ramp on woodstock's express either.

Rob

There's no exit stairway in the animation. But, there IS on the actual ride.

See the outriggers on this track piece? http://www.pointpixels.com/4images/details.php?image_id=8084 That's to mount the stair to.
