Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 164. Works numbers were 27039 in December 1905 and 31643 in September 1907.
Logging roads had distinctive characteristics and one of them, according to the specs, was "average speed 15 miles per hour, sometimes 30". One supposes the 30-mph speed for these wood-burners must have been on the straightest, flattest sections. These were pretty big and powerful 2-6-0s for the 3-foot gauge. Both served W T Smith until they were scrapped in 1944.Data from Logging Locomotives 1913 (Philadelphia, Pa: Baldwin Locomotive Works, 1913), p 13 and DeGolyer, Volume 41, . 7. Works numbers were 38303, 38409 in September 1912.
This was a pretty big wood-burning Mogul design. When the WT Smith company of Chapman, Ala bought the standard-gauge Empire Lumber Company in 1912, the motive power had to follow suit. #8 was scrapped in 1948, but #7 was bought by the Union Camp Corporation. Later put on display in an increasingly dilapedated condition in Kershaw, Ala.
