Kinston & Snow Hill 2-4-0 "Porter" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 13118)

Data from DeGolyer, Volume 30, p. 245. (Thanks to Chris Hohl for his 24 January 2017 email reporting the tender's fuel capacity.) Works number was 29970 in January 1907.

The Hines Brothers Lumber Company in Lenoir County, North Carolina went very small when it bought this little six-wheeled wood-burner with separate four-wheel tender that carried just 3/4 of a cord. Controlliing sparks was a critical part of logging operations and the 2 sported a 9" (227 mm) Radley & Hunter stack.

The logging railroad measured 25 miles (40 km). When the K&SN and the Kinston-Carolina were consolidated in 1912 as the Carolina Railroad, its mileage had been reduced to 15 miles. The CRR was a subsidiary of the Norfolk Southern.
