Natchez, Columbia & Mobile 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 6 (Locobase 12995)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p. 157. Works number was 29251 in October 1906.

The Butterfield Lumber Company of Norfield operated this southern Mississippi railroad, which it opened in 1892. It never actually reached any of the three cities in its name and ultimately amassed 33.2 mainline miles from Norfield to Oakvale. Its mixed train included not only log cars, but also a mail coach, passenger coach, and other general-merchandise freight cars.

After 12 years with the NC & M, the 6 was sold in January 1918 to Denkman Lumber Company. Denkman sold the 6 to Pearl River Valley Lumber in 1933, but bought it back in 1938 and sold it again in January 1946 to King Lumber Industries. KLI scrapped the 6 in 1950
