Carolina Timber Company 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 35 (Locobase 12992)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 15, p. 37. Works number was 9888 in March 1889.

Locobase shows another locomotive with exactly the same dimensions supplied to a logging company in 1888 (Locobase 11593). The only difference was a 30-psi increase in boiler pressure.

The 35 later worked for Interstate Lumber, then for Dill Cramer Truitt Lumber Company of North Carolina.
