Ingham-Burnett Lumber Company / Irish Bayou Lumber Company 2-6-2 "Prairie" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 14156)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 48, p. 291. See also "Research: Tram & Railroad Database" on the Texas Forestry Museum website at [link]; and Vista K. McCroskey, "San Augustine County," Handbook of Texas Online, accessed December 01, 2024, [link]. last accessed 1 December 2024. Works number was 40317 in August 1913.

The IBLC was located in Sturgis, San Augustine County,Tex and opened in 1913. It was financed by four men from Keltys. The TFM's description contends that the name of the railroad should be the "Ayish Bayou". Vista McCloskey's baseline ntry for San Augustine County notes that "Ayish" or "Ais" referred to the native American settlements that had occupied the area for centuries. During its colonization by Spanish and later Anglo-American settlers, the area took the name of the Ayish Bayou, which flowed north to south in the center of what would become San Augustine County.

On the other hand, Baldwin's August 1913 specification sheet gives the tank details on the tender sides as IBLC and "Irish Bayou Lumber Company." Apparently this was the very first, and possibly only, engine for the railroad. The design was one of the typical Baldwin light logging Prairies built in the 19teens. It ran on the wooden rails of this timber tram road, which was in use for about 10 years after which the Boynton Lumber Company of Lufkin, Tex. bought it for their use.


Class 22 (Locobase 15220)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 71, pp. 265. Works number was56330 in March 1923

Ingham-Burnett was incorporated by partners SK Ingham, EL Burnett, and Ross C Smith in July 1922 and was headquartered in Allison, Ala. Its ruling grade was 4% and curves bent at a relatively mild maximum of 20 degrees.

Among its first new locomotives was this very typical multi-fuel (wood and coal) logging Prairie. More than two dozen logging companies had bought this particular Baldwin 2-6-2 design over the past few decades.

Hutchison-Moore absorbed Ingham-Burnett in 1927 and continued to operate the 22 for a few years. It was sold to locomotive rebuilder/reseller Southern Iron & Equipment in 1933.
