It's a wire, actually.

Are your criteria Adelaide-specific?

Melbourne had a wonderful cable tram system with no overhead. London and
Washington DC had tram systems with underground current collection through a
slot between the rails.

Travel to a place like San Francisco some time and see how ugly overhead can
get. They have trolley buses as well as trams. The system is complex and
bulky and looks like a copper overcast at some intersections. Overhead is a
necessary evil, not a desirable attribute.

Michael and other members,

I don't know about the rest of you, but a tram can
only be a tram if there are overhead cable for
electricity. If they remove that, then it will lose
for me all that a tram is, and won't look good.

Cheers, Troy

On MMMs Buttscuttling (a local radio station
competition where people ring 
in with gossip in the hope of winning a prize) this
morning, someone 
claiming to work for the 'local' company which builds
/ installs the tram 
tracks in Melbourne claimed that between now and the
Commonwealth Games in 
2006, all the overhead tram lines would be removed and
the power provided 
from an on ground system. He was pretty vague about
the on ground system and 
the implication seemed to be that the power would be
provided similarly to a 
model train ie power in one track and earth on the
other. He claimed all new 
track laid recently had the capability for the 'new
system' built in. 
 
It sounds like a load of crap to me although he won
the $500 prize. My 
questions to the more knowledgeable people are: 
 
1. Is there any truth in it? Are there plans to remove
the overhead wire? 
 
2. For interest sake, what are methods other than
overhead wire of powering 
trams? 
 
Some obvious ones I thought of were the battery trams,
diesel engine powered 
trams, a conduit underground with the power and I
think there is some system 
with studs in the road. Any others? I haven't included
the model train 
system for the obvious reason it probably woldn't be
practical from a safety 
viewpoint (750V DC anyone...)
