Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 23, p. 247. Works numbers 18802-18804 in March 1901.
An indication of what lay in wait for the thre eMoguls in this order comes from the specs, which include this succinct note: "Bad water, poor track, short [sic] curves ...W[eigh]t on any axle not over 27,600 lb."
