In order to conserve space and money, Imagineers redesigned the entire ride system for the attraction at Disney's California Adventure.

The attraction features three elevator shafts. Each shaft, in theory, is its own separate ride with its own separate operating system. Doing this made it easier to repair individual areas of the attraction without causing the entire attraction to go down. Each shaft has two vehicles and two load levels. It is designed so that the lower vehicle can be in its ride profile while the upper vehicle is loading, giving the attraction the ability to move its line much faster.

Since each vehicle loads and unloads from the same point, it ended up saving space. Due to the smaller budget and fewer breakdowns, Disney used this system again in Paris and Tokyo.
