In 1884, the São Paulo Railway received three tank locomotives from Nasmyth, Wilson & Co., which had a 0-6-4T wheel arrangement. Since the number 1 had already been scrapped, they were given the numbers 1, 23 and 24. It was unusual that these locomotives, in the style of the later “Cab Forward” locomotives, always ran with the coal bunker first to keep the smoke gases away from the crew. The drawing shows that the cowcatcher and the headlight were also mounted on this side.
