Ingham-Burnett Lumber Company / Irish Bayou Lumber Company 2-6-2 "Prairie" Locomotives of 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. Works number was 40317 in August 1913.

The IBLC was located in Sturgis, Tex and opened in 1913. It was financed by four men from Keltys. This logging Prairie was later sold to the Boynton Lumber Company.


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.
