An American Locomotive Company - ALCO RSC-3 locomotive, #654, at the Jundiaí maintenance works, being tested with a dynamometer car. Similar locomotives were also supplied to E.F. Central do Brasil. As there is a LEW locomotive from the Companhia Mogiana behind the RSC-3, probably this photo was taken in the late sixties or early seventies. This photo was shot by Paulo Modé; this copy was kindly sent by Alberto Henrique del Bianco to the E.F. Brasil site.
