Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 23, p. 185. Works numbers were 18565-18567 in January 1901.
Locobase has two entries with the same builders' information because Connelly's listing shows only one set and Baldwin's specs show two different orders.Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 23, p. 184.
