Jackrabbit will not be the only coaster an Kennywood to have these next season.  PR will use these as trims over the last two bunnies before the transfer. Check out this link:

That certainly looks like the Jackrabbit.  (It is receiving magnetic brakes this season) Ace News ran a story about this recently.  It seems Kennywood, if happy with JR, will possibly add these to all their wood coasters.  Some interesting adjustments had to be made to the tracik/structure and trains to permit this modification.  I bet John Miller never imagined that!

You can see the ones on PR under "applications" on the same page bigkirby linked to.
Seems like Kennywood likes this product. :)

Hmm, interesing.  Where is that PR trim placed?  (please tell me that's the ascent to the brake run)
It would seem that this company is offering a combo pinch/magnetic brake.  Cool!

Let's see if we can all link to the applications page. ;)

Peabody - I think that break is located on the bunny hop between the turnaround and the station.

These look much more efficient then the Intamin style ones, because they dont have to move into place, and the accident on S:ROS wouldnt have happenned with these.

Yes, Jack Rabbit will run this year with it's brand new magnetic braking system.  PR's magnetic are on the final two rises into the friction brake run.  If you can imagine to final two hops into the brakes, the magnets are located on those two hops.  The ride is basically uneffected as far as airtime goes.  It is still amazing air with two train operation.

The Intamin brakes are often stationary as well, it just depends on the application. None of those shown on that site are for the purpose of stopping the train, in particular the Kennywood applications.

Millennium Force uses a whole series of them to slow down the train, and nearly stop it when it's empty. The train keeps moving because it's on a slant, ditto for the Jack Rabbit.

The faster the fins move through the magnets, the more force there is to stop it. S&S had a little setup of this at IAAPA that demonstrated this in terms a human could experience. A little "car" on a track moved pretty freely through the magnet, right up until you tried to move it through quickly.

You can us magnetic brakes to slow the train without stopping it and leave them ridgid.  However, if you use them to bring the train to a complete stop you need to be able to disengage them, or you will only be able to move the the train forward very slowly.
