How would this aerial gondola system work?

The LA ART aerial gondola system would include cables, passenger stations, towers, a non-passenger junction, and gondola cabins. In an aerial transit system, cabins are suspended above grade by cables strung between stations and towers/junctions.

LA ART is proposing a Tricable Detachable Gondola (3S) system (the most advanced technology currently available), utilizing high-capacity cabins to efficiently transport passengers. 3S systems use three steel cables to support and move cabins. Two stationary cables provide stabilizing support, while a third cable continuously circulates the cabins.
