The lifts in the World Trade Center went up only half-way and you had to get out and "change trains," at least when I rode them in the early '80s... Fastest elevators I ever rode.

The article is mistaken about changing elevators in a super tall building. It's not cable length (if it was then explain the express elevators to observation floors) but to reduce the real estate devoted to shafts as the local cabs going up from the first sky lobby can be in the same space as the cabs from the lobby that handle the lower floors. And then the elevators from the second sky lobby can use the same space yet again. Otherwise a huge amount of space is taken up for shafts if each went all the way down to the bottom.

This technology has been long in coming and has many possibilities. Elevators going up in one shaft then crossing over and going down in another. They move forward to the door when stopping so other cars can pass behind them. In a large complex one might board an elevator in a parking structure go down...horizontally...then up directly to the destination floor. Maybe not so great for the little stores in the building lobby. LOL
