Sorry, that was just a free-association comment I made based on a lengthy discussion some of us here had this past winter regarding Hyperion Wharf trolleys.
I live in SoCal, where several big, fancy outdoor malls have these custom built trolley systems that circulate shoppers around the retail/dining/housing that are intertwined in the malls. The vehicles are fully wheelchair accesible and gorgeously crafted and piloted by conductors in fancy uniforms more polished and upscale than anything on
Main Street USA. :lookaroun
There's one of these trolley malls just down the street from WDI headquarters in Glendale, so I know the Imagineers are very familiar with the concept of trolleys zipping around outdoor shopping malls.
Glendale, California Mall Trolley - The Americana Shopping Center
Los Angeles, California Mall Trolley - The Grove Shopping Center
Wouldn't those be neat zipping around Downtown Disney, connecting one side of the sprawling facility to the other? And when I say zip, they really can
zip, as seen in this 20 second YouTube clip of a trolley at The Grove moving down the mall at Christmastime.
