Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 8, p. 100. Works number was 4297 in March 1878.
At no time did the three-foot gauge ever seriously rival standard-gauge railroads in number or mileage in the United States, especially east of the Mississippi River. But there were periods when the apparent advantages of smaller everything seemed compelling. Thus when the D&K announced it was building a 27 mile (43.5 km) narrow-gauge line from Delphos, Ohio to the Indiana line, it was not a completely wild idea.
The D&K was part of the Toledo, Delphos & Burlington Railroad, a mini-conglomerate of skinny-gauge lines assembled by Dr C A Evans and J Boehmer that included the Delphos Bluffton & Frankfort Railroad, the Frankfort & Kokomo (purchased from the Seney Syndicate in 1881). In turn, Joseph W Hunt folded the TD&B together with the Frankfort & State Line; and Marion & Ottawa to form the Toledo Cincinnati & Saint Louis Railroad in February 1882. (The Cincinnati Northern joined them in May 1883.)
This little tank had a diamond stack, but was clearly not to be the main motive power for this road. In fact, this engine's entire career lasted just four years.When it joined the TD&B, it took #4. Alas, it was as the TC&StL #4 that the engine wrecked in June 1882. Its boiler would continue serving for some years afterward.
NB: The direct heating surface was calculated by assuming a cubic firebox and adding up the calculated square areas of the front tubesheet, the two sides, and the crown sheet. It is an estimate, but one that gains credibility with several other Baldwin designs with exactly the same firebox (e.g. Locobase 12024) for which the area is known.
