During the mid fifties the population of São Paulo and its neighbouring cities skyrocketed, as that place was the epicenter of Brazil's industrialization boom. Commuter services never were very good, but they worsened a lot at those years. Then E.F. Sorocabana came with an emergency solution: the adaptation of freight cars to commuter cars, like the one you see in the photo, shot at the Júlio Prestes station. Their users nicknamed them as Caveirão ("Big Skull"). Such not-so-tranquilizing nickname apparently came from a construction detail: look to the white central doors of the car (the "head" of the skull), with its two large dark windows (like its "eyes"...) and the central door bolt (the "nose"): the image vaguely ressembles the "face" of a skull... These units generally were used as supplementary cars of the Carmen Miranda electric multiple units. This picture, originally published in the July 1954 edition of the magazine Observador Econômico, was kindly sent by César Sacco, from Indaiatuba SP.
