Colm Moore:
(1) Batteries: is there room for them underfloor on an Alsthom tram?
(2) Buried power supplies: OK not a 3rd rail, but in principle the same problem: a whole extra pickup system for the power: is it doable?
(3) "Only the trams to be used on that particular section would need it". Can you be serious? if the sensitive location happens to be the city centre, then either all trams will have to be fitted, or else it's all change at Sthepen's Green, and again somewhere else on the North side.

Bordeaux has such a system, but the point is that it was specified at the outset. Retrofitting would seem to be extremely cost-ineffective.
