Really think it's about time the government "bit the bullet" and resolved to just call them all TRAMS. It would simplify interaction with the public and avoid any confusion. I always thought using "light rail" was to avoid people thinking of toastracks etc and to sound "modern". I know we've had this discussion elsewhere but I REALLY can't see how you can call Newcastle, CSELR or Canberra "light rail" and not "tramways" - they're all "in or adjacent to public streets". As to IWLR, what's the point of distinguishing between the on- and off-street sections?
Melbourne has trams (though they tried the "light rail" thing with Pt Melbourne/St Kilda), Manchester has trams, Sheffield has trams etc. Give up Gladys!
