With a POD after 1820, have the capability at any point to ride passenger rail from New York City to Buenos Aries. No more than 10% of the distance may be done with alternate forms of transportation. So a ferry around the Darien Gap is OK, but not a ferry from Miami to Belem.

(Decades of Darkness *may* manage to pull it off, but the POD is in 1809)
