Often wondered if there is an application for a streetcar/tram or
electric/trolly bus that runs under wires where practical, but
utilizes batteries for stretches where wires are not practical, or
unsightly.


Route number 3 in Gent is a trolley bus. I've seen them run short
stretches away from the wires when going to or from the depot so they
must have batteries.

The Silver Line services in Boston are operated by dual mode vehicles -
they run as trolley buses through the in-town tunnels, but then use a
diesel engine to drive a generator that powers the motors when above
ground. See http://en.wikipedia.org/wiki/Silver_Line_%28MBTA%29
