Trains
"The passenger rail network in Brazil is extremely limited and not a viable option for travelling around the country. There are, however, a number of scenic routes. Brazil has only 17,500 miles of railways compared to over one million miles of roads." Currently plans are underway for a high speed railway connecting Rio de Janeiro and Sao Paulo for the 2014 FIFA World Cup and 2016 Olympic Games.
