Columbia, Newberry & Laurens 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 22 (Locobase 12829)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 53, p. 391 and Volume 65, pp. 76+. (Thanks to Chris Hohl for his 28 February 2016 email noting the typo that showed 600 US gallons of tender water capacity.) Baldwin works numbers were 45827 in June 1917 and 54068 in November 1920.

Locobase 12828 shows the 1915 Consolidation (21) that Baldwin delivered with a saturated boiler. A year and a half later, the same design was produced with a relatively sizable superheater in a boiler that sacrificed 139 small tubes for 24 flues. The hotter steam called for 10" (254 mm) piston valves for steam distribution. Firebox heating surface area included a nominal 10 sq ft (0.93 sq m) in two arch tubes. The 21 received a superheater in 1930 and Locobase suspects it had the same dimensions as that of the 22 and 23.

Both the 22 and 23 were sold for scrap in November 1951 with the 23 valued at $24,945 at the time.


Class George Foulk (Locobase 12828)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 51, p. 343. (Thanks to Chris Hohl for his 28 February 2016 email noting the typo that showed 600 US gallons of tender water capacity.) Baldwin works number was 42772 in December 1915.

This was the last Consolidation delivered to the CN&L with a saturated boiler; the next one would have a superheater and the George Foulk would be so fitted in 1930. See Locobase 12829.
