The way I assume this will work is that stationary Gondolas (multiple) will be "stacked" up in the secondary load/unload area. As someone boards/loads in the secondary area a gondola will be pulled off the primary line into the secondary load/unload area on the upside of the cable (entry point). Then as that "opening" comes around the loaded gondola will slide right into the empty spot.
This allows peak efficiency for the system (leaving stacked empty cabins for secondary loading, keep gondolas at perfect spacing). I assume if a gondola comes in loaded with an
ECV and needs to go to the secondary area they will go into the area and just fill the empty space with an empty gondola. The only issue I see to this "peak" efficiency is that a Gondola comes in that needs to be unloaded at the exact moment they are loading up an ECV. However, the system should know where ECV loaded gondolas are and can hold off on filling in those in the secondary a few moments to avoid this issue.
I would assume this requires a "load" and "unload" side of the station because they can't walk around the entire station. But I don't know that for sure; however, crossing issues aside, from a flow of people too that would make sense.
