The São Paulo railroad network plays a fundamental part in Brazilian inter-regional transportation. It connects the producing regions of the states of São Paulo, Minas Gerais, Bahia, Sergipe, Goiás, Mato Grosso and Mato Grosso do Sul to the Tietê- Paraná Waterway and to the ports of Santos, Rio de Janeiro, Itaguaí and Guaíba. One of the branches connects the Port of Santos to Paraguay and Bolivia, with prospects of serving as a connection between the Atlantic and Pacific Oceans in the near future.

An important part of this network connects the municipal districts of São Paulo and Rio de Janeiro, passing through the country’s main industrial region. In 2011, this corridor transported almost 130 million tons of cargo, mostly steel products, sand, cement, iron ore and general cargo.
