Where are yall picking up this "first LIM" deal with Screamin? It's not even the first Intamin to use that exact type of LIM, the only "new" element to it is the most inefficient and overcomplicated lift hill known to mankind, and for some bizarre reason it didn't even open with magnetic brakes despite the trains being ready for them. Linear Gale and Volcano both opened as Intamin inverted LIM coasters in 1998, and the first Premier spaghetti bowl LIM coaster in 1996. Heck, look across the esplanade and you'll see LIM's on a 1979 coaster.
It is the first and only as far as I know to use liquid cooling. Those misters on the launch aren't just for show.
What, the topic was about 6 trains? Oh right, sounds like fun.
