Long distance freight can be efficiently transported by rail, then moved
to a truck at an "intermodal" terminal for local delivery.
Electric buses are more viable. I remember, as a child, traveling on
electric trolleybuses in Brisbane. In 2014 I took one from the center of
Vancouver to the University of British Colombia:

Trolley buses require more complex overhead wiring that trams, but they
do have the advantage they can maneuver, to a limited extent, in traffic.
Battery technology has reached the point where it would be feasible to
use electric buses, without the need for overhead wires. However, if the
electricity is from fossil fuel power stations, there is no great
environmental advantage over using compressed natural gas (CNG) buses.
For Canberra's next transit project, I have suggested a busway using CNG
hybrid buses, rather than trams:

In 2006 the ACT Government looked at the option of a tram from the north
western satellite town of Belconnen to the center of Canberra. I, not
entirely seriously, proposed an "Electric Highway":

What was implemented was a conventional bus-way:

To get this discussion on-topic for Link, I suggest IT can be used to
make "public" transport more usable and environmentally benign. As an
example, an Uber-like social transport planner could combine the
features of taxis and buses. With this you would indicate where you
would like to go, when and how flexible you are as to time and cost. You
would then be offered the usual options of a dedicated car with driver
(expensive and quicker) or an ordinary bus (slow but cheap). But there
could also be options in-between: a car with driver shared with three
people in your social group, or a mini-bus with six people who you don't
know, but the system vouches for. The more willing you are to travel
with strangers, the cheaper, and sooner, would be the ride.
Taxis have multi-ride rates and in the past, in busy periods at
Canberra airport, a taxi company wrangler would shout to the queue:
"Anyone for Belconnen?".
