A Simplex Decauville locomotive of Fazenda Araraú. This machine shows a slight modification from its original design: its cooling system was formerly driven through a pulley, but now it is coupled directly to the motor crankshaft. So the radiator location has changed from its original frontal position to the side of the locomotive. Photo shot in 1994 and kindly sent to this site by Nílson Rodrigues, from Franco da Rocha SP.
