North Carolina Lumber Company 2-6-2 "Prairie" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 15313)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 73, pp. 425+. See Locobase 13446 for brief history of the WLC. Works number was 58267 in March 1925.

In early 1925, the North Carolina Lumber Company of Lake Waccamaw, NC ordered the 5, which resembled the earlier Waccamaw Lumber Company logging Prairie locomotive shown in Locobase 13448.

It's close to being a duplicate and certainly was headed for the same kind of duty in the same part of North Carolina. The NCLC was incorporated in 1910 with a capital investment of $125,000. Its base at Lake Waccamaw (about 30 miles/48.3 km west of Wilmington) lay within six miles of Waccamaw Land & Lumber.

But the locomotive was not only a decade younger but weighed less and its tender weighed more. The 5's firebox was smaller while each of the tubes was 5" (127 mm) longer even as wheelbases shrank.
