Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 33, p.144. See also Donovan L. Hofsommer, "QUANAH, ACME AND PACIFIC RAILWAY," Handbook of Texas Online ([]), accessed November 29, 2011. Published by the Texas State Historical Association.. Works numbers were 33365 in April 1909 and 34523-34524 in April 1910.
Purchased by the Acme, Red River & Northern, the first of these three Ten-wheelers was lettered during production for the more grandly conceived Quanah Route. Acme Plaster had sparked the opening of the ARR&N in 1902. Owner Sam Lazarus had built 13 miles from Red River to Acme, but in 1909 he hoped to extend the railroad southwest to El Paso and hook up with the Southern Pacific. He added 35 miles to reach Paducah, Tex, another 39 to McBain in 1913, and eventually tacked on another 26 to reach Floydada, 119 miles from Red River.
Although it never reached El Paso, the QA&P mainline proved highly useful to both the Frisco and the Santa Fe and the Quanah Route remained in service into the 1970s.
