I have two questions. What is the purpose of the extra rail on each track is for use by both standard gage and wide gage? Question two; Does Australia still use wide gage equipment?

Gday David, yes, the extra rail is for dual gauge operation (broad and standard). In Victoria, broad gauge (5'3") is still used around a reasonable amount of the state, although some conversion to standard (4'8 1/2") has occurred.
