Well appart from hills and the obvious Charlemont, is that a possibility? I mean looking at the pantographs you would think so, then again for a fast frequent light rail service moving people up and down the stairs and buying in new trams to operate it might be an issue. Its been done before, may be we can do it again!
Come to think of it, based on other projects there would probably be something small that will be blown totally out of proportions by the press and the TD's that would block the thing we call "Progress".
