A G.E. 510 HP electric switching locomotive, nicknamed baratinha ("little sow bug"), built in the roaring twenties. A similar locomotive can also be seen at the Companhia Paulista page. They had a marvellous sharp melodious whistle, which will not be heard anymore: they were scrapped in the early nineties. The copy of this photo was kindly distributed in the E.F. Brasil, an electronic list for discussion about the Brazilian railroads, by Paulo César Bonaldo.
