- Should the lines go under the oceans? Yes I supposed so - this is a fantasy underground map after all.
- What should constitute a station? Should it go on city population or general area population? A great deal of Canada would suffer from severe stationlessness if either of these became the rule, so a mixture of both with a dash of common sense and aesthetic licence was to be employed.
As I was in this part of the world it seemed like a logical place to start. I reckoned that a line covering east coastal Australian cities might do well to carry on through Papua New Guinea and up the Eastern Asian seaboard, a line could take in Alice Springs and Darwin before moving into South East Asia, and another could cut across to the west of Oz before moving up into India. As it turned out, Perth was the last stop on that line as the Darwin line took in India.
This part of the map was a joy to create along with many other parts; many regions proved to be a nightmare!
