To introduce recent historical research on railways in Brazil, the case of one of its states makes a useful example. Concentrating on railway history in São Paulo will permit a more historiographical and thematic point of view. The São Paulo state railway is of particular significance in Brazil. At 4,041 km in 1907, it accounted for more than one-fifth of the total extent of all Brazilian railways (17,605 km), well ahead of runners up in the states of Minas Gerais (3,932 km) and Rio de Janeiro (2,422 km).2 The state of São Paulo also led in cargo transportation. The São Paulo Railway Company alone transported 1.9 million tons of cargo. Among the six most profitable transportation companies in Brazil, four were in São Paulo: São Paulo Railway Company, Sorocabana Railway Company, Paulista Railway Company (Companhia Paulista de Estradas de Ferro) and Mogiana Railway Company (Companhia Mogiana de Estradas de Ferro). Doctoral theses and academic papers on the history of Brazilian railways have grown in the last ten years, and studies of São Paulo predominate.
