Comparative subway study, part 2

Porto Alegre has a subway as well, so I feel like I should say something about its system. Porto Alegre followed São Paulo’s boring lead and chose the name of Metrô but adds the hopeful “Linha 1.” The above ground single route is useful and carried me from the airport to downtown, but as far as I know, there are no plans for Linhas 2 or 3.
