Data from Baldwin Locomotive Works Specification for Engines, 1890, as digitized by the DeGolyer Library of Southern Methodist University Vol 20, p 103. Works numbers were 14697-14715 in February 1896; 14724-14736 in March.
These Vauclain compound Ten-wheelers were powered by naptha. Within a few years, they were described as being "well-used" because of the increasing weight of passenger trains.
