Trams in Melbourne
In Melbourne, the best way to travel around the city is using Trams. I did, that is very comfortable and high frequency service. Normally, I only need to spend five mins for waiting. Moreover, that is a free city circle tram. That is for tourists and they use some historical trams to serivce.
Too bad, Brisbane has not trams services.
By the way, I did a google search. I found some information from Wikiepdia. Melbourne Trams is the world largest network and more than hundred years old. Go to http://en.wikipedia.org/wiki/Trams_in_Melbourne, find out more.
