> A working brake van? I'm fascinated. Please explain.
I'll sit down and Ldraw some of it, but not right now...I just don't have all
that much time. It uses a small Pnumatic cylinder mounted in the car, driving
down through a 2R curve (the 2x2 macaroni bricks, stacked) pivot point, to the
Technic cam pieces via 2 sets of angle gears. Kind of neat, but intricate. It
was worth about a motor for brake effect...but, a lot of fun.

The Limacion is NOT mine! (have to add that)

Been there, done that, got lots of photos to prove that Mindstorms can crunch
coal cars into little bitty lego chunks :).
I built both a loader (mine) and unloader (rotary dumper). Both were
mindstorms controlled, and all that is left is the lock/table from the dumper
now. (I have 3 buildings left to take apart from my city, I am moving across
Canada again in 3 months...)
> How steep is the rise you are using, James?
I used wood, rather than Lego. Therefore, exact lego grade is unknown, but
around 1.3 bricks/section of track. I had 12.3 space between the rail and the
closest objects (lego bridges, in fact). This is not really enough (quite) for
some of what I had built/gotten. The 4551 is too tall for it with the full
pantograph arrangement, and so is 4552.
My city/layout can be seen at:

(hmm...I was looking, but no real photos of the room as it was...ah well. Much
of the lego stuff is in there, but none of the room in total.)
