Of course, where there were tramlines already, they could use
those, but they were horrendously impractical.

Of course, you'd have to modify the tramlines with the return wire as
well. (Trams only need one wire as they return the current through
the rails).

Only one wire? What's all the others for then? It's a bloody mess up
there for Croydon Tramlink.

At least when you have trolleybuses you ONLY have two!

Proof? Have a look at

Only two? Er, have you seen this ...?

Don't be silly - you know that the picture is of a trolleybus
yard/garage/depot which was built/created many decades ago. But then
I ask you this question: Which is better: electrical pollution
[allbeit enviromentally friendly] in the sky or diesel fumes in your
lungs? I know which I would rather have.

A trolleybus depot and surrounding stabling areas if built today would
have NO overhead wiring, or for that matter traction wire supports.

Doesn't get away from the fact that tramway overhead is much more
complex than that which would be built for trolleybuses.
