Class Details by Steve Llanso of Sweat House Media
Class Esther (Locobase 13345)
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 32, p. 56. See also a summary of the railroad at the Coal Mines of Westmoreland County, Pennsylvania, [
], last accessed 1 November 2011. Works number was 33215 in February 1909.
An indication of just how much coal lay under western Pennsylvania is illustrated by the origins of the Latrobe-Connellsville Coal & Coka Company. In 1865, Matthias Saxman started mining coal from his farm. The business grew quickly and Marcus Wilson Saxman bought several other companies including the L-C C & C. By 1913, Saxman's holdings amassed enough coal potential to be the seventh largest coal company in the United States.
According to the Millwood entry under the same site, this locomotive "...was used at the Millwood Shaft Mine, Millwood Shaft, Derry Twp ....[It] was the largest engine owned by the Latrobe-Connellsville Coal & Coke Company."
