It would be elevated and constantly moving. In order to travel faster on the main track it could divert to multiple loading platforms at each station. There are more than a few questions to be answered with regard to this idea, but it could potentially work. I'm not sure if it would cut down on line time or make the lines longer if the Peoplemover loads fewer people at a time and travels slower than the trams though, but this can be fixed by altering the Peoplemover to make it much bigger. And I'm sure this has been brought up before... And also, this would fulfill the Peoplemover's ultimate purpose: to be used for real transportation in the future.
What do you think?
