Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 18, p. 44. Works numbers were 12774-12777 in June 1892.
The only information Locobase can turn up on this quartet of metre-gauge Moguls is that they were rated to pull 200-210 tons up a 1% grade and 250-260 tons up a 0.8% grade.
The DeGolyer Library's Class List shows the class was originally ordered by H M Bary. The DeGolyer collection's list of Erecting Diagrams indicates that this was only a proposal even though works numbers were assigned.
