In 1865, the São Paulo Railway received three passenger locomotives with a 2-4-0 wheel arrangement from Sharp, Stewart & Co. It was only shortly before the turn of the century that their frame was lengthened to accommodate a leading bogie. The picture clearly shows that the frame protrudes a little further over the smokebox. They had inside cylinders measuring 16 by 22 inches and driving wheels a relatively modest five foot in diameter.
