Rio de Janeiro
Rio has more people living in slums than any other city in Brazil, according to the 2010 Census. More than 1,500,000 people live in its 763 favelas, 22% of Rio's total population. São Paulo, the largest city in Brazil, has more favelas (1,020) in sheer numbers, but proportionally has fewer people living in favelas than Rio.
Rio–São Paulo high-speed rail
It is tentatively planned that the trains will have a capacity of 855 passengers at a headway of 15 minutes. The fare will be around R$150 to R$250 per passenger in the off-peak hours. There are several projects presented to the Brazilian government. One is the Italian design company's Italplan Engineering Environment & Transport Srl, whose proposal envisaged the high-speed train starting operations in 2015. If this target date is met it will serve as a quick and vital link to São Paulo in time for the 2016 Summer Olympics.On May 13, 2008, it was reported that a high-speed line between Belo Horizonte and Curitiba would be included in the National Transport Plan. It would link Belo Horizonte, Divinópolis, Varginha and Pocos de Caldas (all in the state of Minas Gerais); Campinas, São Paulo, Sorocaba, Itapetininga and Apiaí (all in the state of São Paulo); and Curitiba (in the state of Paraná). The line would be around 1,150 kilometres long, about twice the length of the line between Rio de Janeiro and Campinas. The resultant network, centred on São Paulo, would serve an area containing more than half of Brazil's economic output and population. The line is scheduled to be built after the completion of the line between Rio de Janeiro, São Paulo, and Campinas.
