National Geographic's book "Journeys of a Lifetime: 500 of the World's Greatest Trips" features the Melbourne 96 Tram (). If you have the time this is well worth the ride. It goes from the center of the city to the beach, incluidng a section along what was the St Kilda Railway.
Unfortunately the book did not include the Adelaide to Glenelg Tram, which must rate as one of the great light rail trips of the world (12 km from the center of Adelaide to the beach).
Ps: Other trips in the book include Toronto's 501 Queen streetcar.
