Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 8, p. 177; and ""Sayelsville" - Number 4" on the Moshassuck Valley Railroad website at []; and "Two Mile Railroad with Two Locomotives and One Bridge" published in the Boston Globe, 26 June 1904; both last accessed 19 December 2022.. 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. Baldwin works numbers were 4231-4232 in January 1878.
