Rowland Lumber Company 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 14048)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 45, p. 42. Works number was 33300 in March 1909.

This Ten-wheeler was required to negotiate 27-degree curves, which prompted the note: "Co. desires wheelbase as short as practicable without sacrificing steaming qualities."

Its delivery soon generated a note describing some shortcomings: "Engineer Alexander reported throttle lever too short, bill is small, side rods should have been solid ends. Injector has no squirt."

Possibly in pursuit of those "steaming qualities", the railroad converted the 5 from wood-burning to coal-burning soon after the engine arrived. Locobase suspects the Radley & Hunter cabbage stack was replaced as well.

When this Bowden, NC logging road closed in 1935, the 5 was sold to the Bucyrus Erie Company.
