Good trains in Australia?
I was thinking fondly of Japan.
Walk to subway. Train within 7 minutes. Transfer to different line. Train within 5 minutes. Transfer at bullet-train station; buy ticket from machine (maybe $50 or $100, can reserve a seat. No searches, scanners, milling about in departure lounges. Whoosh off to Tokyo or wherever at 270kph. Arrive on time about 99% of the time. And by on time I mean to the bloody minute. And the subway is right there. Door to door there is no way a plane could beat that.
