    We have lots of trollybuses in San Francisco.  They can drive on battery power for a short while if they have to detour off the wires.  However, they run at about 3 mph on battery power.  The real downside of trollybuses is that they have poor route flexibility.

      busses built with today's technology could go for longer distances off the wires.  A bank of lithium ion or lithium polymer batteries could keep the bus going for miles, so it can switch routes, do part of a regular route in an area without power lines, etc.

      are rather short for bus runs (what 12 miles or so, or 60 miles in a day).

      I would think that running buses on pure battery power should be feasible, what with all of that overhead space to place the packs.

      ... for transport oriented development, because it gives far more stability to the transport route than a bus does, where a location that is convenient to a good bus route can either have the bus route pulled blocks away or have a lot of time added to routes in additional deviations trying to be able to claim more area covered without expanding the bus fleet to match.

      You can place more reliance on a station for a high capacity rail line or a light rail line than a trolleybus route, and more reliance on a trolleybus than on a regular city bus route.
