Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 33, p 79. See Locobase 13275 for a history of the railroad. Works numbers were 33610 in July 1909 and 33611 in August.
Baldwin supplied a large clutch of Moguls to this "Devil's Railway", as described in Locobase 13275. In the midst of the continuing production of the basic 2-6-0, the MM bought this pair of Consolidations. Before their delivery, MM's Lawford H Fry wrote to request that Baldwin put in a raised fire door as they had suggested earlier. He reminded the builder that they had recommended the modification as a way to allow either coal or wood burning.
Fry continued: "For the first few years the Company are concentrating all available labor on the construction of the road and are purchasing coal in preference to using labor to cut wood locally. When however, the construction work is over they propose to make use of the wood, which can be obtained in abundance along the line for fuel."
