Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 79, p.222. Works number was 59697 in November 1926.
Described as a switcher, this wood-burning Mogul tank was nonetheless a superheated engine with 8" (203 mm) piston valves. Like the other SOe do Bahia locomotives, this little locomotive later operated on the subsidiary Nazareth railway.
