If there was an elevator, they'd want to make it expensive. I'd expect something like requiring redstone in making the tracks that I'd expect it to require.

If they could be redstone operated traps would suddenly have a greater potential for intricacy.

EDIT: Ench mentions in the next post that my post didn't make grammatical sense, so I've re-written it. It's an atrocious block of text and I'm ashamed of it. I've decided to leave it up there for comic reasons.

I'd hope that elevators would be costly to build and maintain. If they used tracks as Ench suggested, the tracks should require something like a unit of redstone dust or two to craft.

If it were possible to control elevators with redstone circuitry, there would be huge potential for better traps to be created.
