might be a way to think about adding capacity to transit and it might add a bit of glamor or interest, and comfortability. Although a counter comment, such as vis-a-vis historic streetcars (and replicas), would be that it could give the impression that transit is "cute" and for tourists and not really practical.

Buses like this, because of film and television images of London broadcast round the world, are understood to be buses "but" fun.

I wonder if this is the kind of bus model that should be used for circulator like systems such as DC's Downtown Circulator or the "Blue" bus in Georgetown, the Georgetown Connector?
