You missed a thread or five. ;c) What I wrote above pertained only to People
Movers, not monorails.

I wasn't aware the Orlando People Mover was different than the Anaheim People
Mover. The WDW People Mover with its linear induction motor makes it to be a
miniature maglev.
Here's an interesting Wikipedia entry that pertains directly to this wholly
off-topic discussion:

I was unaware that WDW used a different People Mover technology as Disneyland;
people on this side of the country are significantly more familiar with WDW than
with Disneyland. However, having never been to WDW I believed that the two
systems were analogous. Obviously I was incorrect.
