Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 20, p. 214. Works number was 15069..
Locobase didn't create a new entry for this locomotive when he first encountered the Baldwin specs (ca. 2010 or so). Baldwin didn't record heating surface area for the firebox, which stymied Locobase's intention.
When he saw the entry again more than a decade later, he searched for a very similar 0-4-2ST and found the 1910 Bethlehem Plantation saddle tank operating in the Dutch Virgin Islands described in Locobase 13663. Its specs exactly matched those of the earlier Brazilian. (Baldwin's extensive use of templates for many of its components lent itself to easy duplications.)
Espirito Santo began building this railway in 1893. Its first 21 km (13 miles) took the line from Vitoria to Viana. This little tank engine Later extensions led to Matilde and ultimately Cachoeiro, 80 km (49.7 miles) from its origin.
The SdoES merged with the Leopoldina in 1907.
