You will also note in the video just how fast they can release the cars.
The video covers the two cars in front of us plus our car. There were
just 2 cast members involved in the release operation, plus one in the
control room. The work lights in Space Mountain came on no more than 5
seconds or so after we came to a stop. The release of the cars started
almost immediately. You could tell that they have done this before.

I cannot remember which one it is, but there is at least one coaster
somewhere that the last car has a special fixture on it that if the
train makes a mid track emergency stop, the attendants can connect a
special motor that creeps the train home at 5-7 mph.

For the same reason that the steepest grade between railroad yards is
pulling up out of the yard. If you can make it out of the switchyard, you
can make the remainder of the line to the next yard. Otherwise at least
your consist hasn't far to roll back, and you're stuck in a good spot
(barring catastrophic failure.)

Barring wheel bearing failure, or other unusual friction/resistance, any
properly designed rollercoaster should have enough slope in elevation to
gravitationally accelerate a car from any one brake zone to the next.

Not to say that ALL rollercoasters have been designed properly. If you have
ever built a killer coaster on Roller Coaster Tycoon, as I have, you quickly
learn better design.

On the other hand, in RCT, I have intentionally built the "Red Man Parking
Lot Launcher" - one car on a few sections of 80mph launch looper shuttle
station where the business end of track is just three sections that point to
the sky over the fence at the park boundary. If I catch a red faced angry
vandal, I pick them up, place them in their own little fenced off isolated
rehabilitation corner of the park. It has a restroom, a ten cent drink
stand, a ten cent food stall, a dedicated custodian, mechanic and
walk-around character, some cheerfull decorations, trees, flowers, benches -
all surrounded by a fence, and the only way out is to ride the "Red Man
Parking Lot Launcher." Nobody dies IN my park. But still remains the stigma
of a killer track that no-one will board after first use, so it's worth it
to then demolish the ride and rebuild it for the next victim.... er, vandal.

Having the brake be "normally closed" and requiring positive pressure to
open them makes a lot of sense. My guess is that the pressure
required by the braking system would be much greater than a mechanical
spring could provide, which means it would still need to be pneumatic or
hydraulic. In that case, a pneumatic system could be used against that
to keep the brakes open, but then there is still the issue of
calibrating the pressure of the system that closes the brakes. I guess
no matter how you set it up, there could always be a failure point.

As someone who's played waaaaaaay to many hours of RCT2, I can't
help but sit here and laugh my lift hill off.

Next time I've given up on everything else and pull out RCT2, I'm
playing a resource unlimited scenario and build dozens of these
things...
