First electric tram service in
South Australia surely? I thought there were electric trams running in Brisbane well before 1909.
The idea of running a tram line from The Parade through the city and out to the Airport/Harbour Town pops up every now and again. The other ones that get air time are reviving trams to North Adelaide/Main North Rd, Henley Beach Rd, a loop in the north west part of the CBD (something like North Terrace to West Terrace to one of Currie, Grote or Gouger Sts and back to Glenelg) and a line to Colonel Light Gardens.
There are others from time to time. Due to its size and layout, and the continued/expanding presence of trams, its to be expected that you will get proposals like these in various parts of Adelaide, and some of them probably have merit.
