Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 13446)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 32, p.99. See also Gwen Causey, "Brunswick/Columbus Connections: some things the two counties share," Brunswick County Historical Society at http://www.bchs1764.org/brunswickcolumbusconnections.html . Works number was 33303 in March 1909.

Waccamaw Lumber set up in business in 1907 in Bolton, NC (about 25 miles/40.3 km west of Wilmington) as one of the largest mill operations in North Carolina. At the time, they were reported to have 210,000 acres (328 sq miles/850 sq km) of timber available to harvest. According to the BCHS, "The woods operation was unique. The company built a main, standard gauge railroad from Bolton to Makatoka [an 8-mile distance]. Spur roads extended on either side into the various tracts as they were cut. The company built camps at Makatoka, and many of the woods crew stayed there."

The railway was built on the standard gauge with light rail of 45 lb/yard (22.5 kg/metre). By 1928, the railroad had 25 mile of logging road as well.
