Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 15, p. 91. See Locobase 16366 for a skeptical 1877 view of steam dummies and Locobase 11577 for a supporting 1889 discussion of the problems associated with running steam dummies on urban street railways. Works numbers were 10024-10025 in June 1889.
Little Leila and Carrie were two more examples of the steam "dummies" that Baldwin was supplying to street railways across the country. When the RSR was electrified in 1892, Leila was sold to Eureka Lumber Company.
