Well it is getting old and the maintenance work is higher than the
new stuff.

Well the subway uses a 3rd rail, but yes that would not be popular along
open streets where people could come in contact with it.  Trolleypoles on
the other hand are hardly used anywhere anymore it seems.

Allowing higher voltages does not mean using higher voltages though.

Streetcars use 600V as does the subway.  The new Eglinton line will be
750V though and won't have loops for turning around.
