Rio's subway is the simplest in the world: there are only three lines, the last one opened only 5 days before the Olympics, the line n°4 (there is no line n°3 for the moment...)
- Line 1 (orange) and 4 (yellow): line 4 goes from Jardim Oceânico, the beginning of the Barra district to General Osòrio, the beginning of Ipanema and line 1 from General Osòrio to Uruguaì in the Tijuca district. In fact the line is Jardim Oceânico - Uruguaì.
- Line 2 (green) from Botafogo to Pavuna in the extreme north near Ilha do Governador where there is the international airport. This is the line that takes you directly to the Maracaña stadium for the fans.
The trains indicate their color (orange or green). Some stations are extended by "metro-buses" (metrô na surface), on the surface to transport travelers. A ticket (unitario) costs R$6.50 and is valid for only 3 days. It is preferable to buy a prepaid card (which you credit with $10, $20, $30...and buy at the machines) because in this case you don't have to wait in line to buy your unitario.
