The reference for locomotives and railcars
São Paulo Railway No. 21 and 22
Brazil | 1882 | 2 produced
Locomotive Magazine, December 1903

The largest tank locomotives on the São Paulo Railway at the time had a 4-8-0T wheel arrangement and were called “Jumbos”. They were supplied by Avonside and were obviously intended for another railway company. So they came to this railway company in 1882 after they had been re-gauged to 5 feet and 3 inches. The first driving axle had no wheel flanges to improve running characteristics in curves.
