Train travel in an ancient land.

During the early voyages of discovery, it was still quite common for
many sailors to expect to see the edge of the earth, and imagine they
would plummet towards their doom. Setting out from Europe to find
the 'Great South Land' must have stirred those thoughts about 'the edge'.

'Daybreak 2000' was a book with a page devoted to
each country as seen at dawn on January 1, 2000.
