Believe it or not, though I pitched as being a mall, it's not what that originally started as. According to the website "The Tram Station is at Cathedral Junction in New Regent Street, a quaint pedestrian mall refurbished to accommodate the tram route. Built in the 1930's in the Spanish Mission style, the street was planned as a shopping precinct, and marketed as “The Most Beautiful Street in New Zealand”. The first shopping mall ever built in New Zealand; it was converted to a pedestrian mall in 1994."
From what I understand, until 1994, this whole area was the carbarn and switching areas. In fact, they're still in there, but the trams now operate inside the pedestrian mall.
