I have designed a minifig-scale roller coaster that can run on standard
monorail track. Each car can carry up to four minifigs around a loop, and
the cars can run independently or linked in pairs. (I haven’t tried longer
trains yet...)
There are several ways to make rail for this coaster. The simplest is to use
standard monorail track, although there can be some interference with the
gear on the track. But (curved!) monorail track can also be connected
back-to-back, the wheels riding on the edges of the two monorails, making it
possible to create very smooth loops. From a ~4 foot peak, the cars easily
complete the loop without derailing. I have also created track using Technic
pin-in-tube construction, as well as with tiled brick and tiled SNOT-brick.
The last issue is to work out a reliable lift mechanism. I have a few ideas
that go beyond the “string of 3,000 chain link elements” approach, but I’m
open to suggestions.

It’s a neat design, and I like the idea of using monorail track to do smooth
loops. 4ft is a hell of a lift to make out of LEGO though! I’d be happy with
something smaller, even if it meant going without the loop.
Have you thought of fitting more wheels on the vertical spigots to act as
rollers? I suppose you could have wheels underneath the rails too, using this
method. It gets a bit bulky for minifigs, but I don’t know if you could get
round the loop at a lower speed.
I’m interested in anything that can reduce the size of a roller coaster and make
it more reliable. This was my mini one from LegoWorld last year. Whoever took
these shots got a good close-up of the lifting mechanism:

I tried using pneumatic tubing for the rails, but it just kept giving way. It
was a bit too sticky too. Track System isn’t flexible enough to maintain a
gradient, so I had to resort to making my own rickety stairs, which jam up quite
often.
