Rail transport in Brazil began in the 19th century and there were many different railway companies. The railways were nationalised under RFFSA (Rede Ferroviária Federal, Sociedade Anônima) in 1957. Between 1999 and 2007, RFFSA was broken up and services are now operated by a variety of private and public operators, including América Latina Logística, Companhia Paulista de Trens Metropolitanos and SuperVia.
