Guests injured on BTMRR - Paris

I know Screamin' also uses LIMs for propulsion as well @ DCA. Superman: The Escape (Or now Superman: Escape from Krypton) uses LSMs for propulsion.

I know that Coaster does use magnets in the launch system but I'm not exactly sure how.

I think that this should become the standard answer to any questions about how something works, like so:

Guest: "How do you get the Audioanimatronics to move?"

CM: "Magnets!"

*I heard a rumor a long time back that when Coaster was first built the Navy came in and studied the launch system to see if something similar could be used on carriers. Recently I heard that the next carriers to be launched (I believe they're being built now or construction starts soon) will have magnetic catapults. I wonder if the study they did led to this.

Next thing will be to add the Aerosmith soundtrack to the launch of the fighters ! Replace that Top gun music they have been using for the past 25 years !

Its too bad they didn't use them instead of the chains on the lift hills. That first lift is SO noisy and rough on the back !

Doesn't Rock & Roller Coaster use linear induction motors for its launch ?

The chains are actually where the name "Thunder" comes from. Everything that you actually do see happen in that is intentional, along with so many effects that either just never worked right or stopped working along the way and the original Imagineers were not there to fix it. Some very cool effects that we miss.

And the LSM's, I don't remember what that stands for, but it is Linear Something Motor. Sorry to not have an answer.

The LIM's at Thunder are used in the station, on the spurline, and after you go through the dinosaur bones and sometimes will stop before returning to the station.

LSM - Linear Synchronous Motor
LIM - Linear Induction Motor

In the most layman terms possible. LSMs "track" and will activate to "pull" and then "push" the item over each stater (magnet). How? There's usually some sort of transducer on the vehicle to let it (the stater) know where the position of the vehicle is. Therefore it pulls and then pushes.

LIMs are a little different. There's no transducer (as far as I know) on a LIM. LIMs use high alternating current (AC) to induce current into the fins (Screamin' uses copper). It creates thrust and it takes off. Now, on Screamin' I know they use water to cool the LIMs. Reason being is during peak season, launching occurs VERY frequently when running 5-6 trains. LIMs do have a tendency to overheat... Hence the water cooling. There has been times where even with water cooling, Screamin's LIMs overheated.

Yeah, I'm a nerd.
