Hamilton Ridge Lumber Corporation 2-6-2 "Prairie" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 14158)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 48, p. 293. Works numbers were 40462 in August 1913 and 40736 in October 1913.

Like many logging Prairies that didn't burn oil, the pair of HRLC engines could burn either wood or coal and were fitted with "plain bars and drop plate, suitable for both wood and coal," according to the spec.

HRLC was based in Estill, South Carolina, but harvested timber across the state line in North Carolina forests. It was highlighted in 1916 for an innovative blade design for its horizontal saws that had holes along the back to carry the sawdust through the cut and thus keep the blade from overheating.

HRLC suffered the total loss of its box factory in 1922 with damages adding up to $150,000-200,000. Although Locobase cannot say for sure that this led to the company's demise, he does know that these two logging Prairies soon found other homes. The 2 went to work for North Carolina Lumber Company. 3 was sold to locomotive rebuilder/reseller Birmingham Rail & Locomotive, which sold it in June 1928 to Leigh Banana Case Co of Ellenton, SC.
