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...)

Don't be afraid to try something new.
