Data from 1903 MO & NA locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 29, p. 149. See Locobase 6638 for a short history of the road, including a discussion of the 1914 accident that took 43 lives. Works numbers were 31314, 31335-31338 in July 1907.
All of the class was retired in 1933 and scrapped in 1934.
