Even here in the southern hemisphere blacks are over represented on buses and trains. In the cities mostly but I did use to catch a long distant over night bus and sometimes the train and there were always to many pacific islanders (Samoans ect) on them. More than whites at about ten to one.
In the US, almost every minor city has an airport, and then most people will drive from wherever they land to where they're going: either rent a car or get a friend to pick them up. Taking a bus is cheaper, although, if it were not for the crowd, more pleasant and just as fast a lot of times. Trains here suck, though. Unless you are traveling along a specific East Coast corridor, the trains are intended for freight and act like it.
