Singer Manufacturing Company 0-4-2 Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 9 (Locobase 13035)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 29, p. 258. See also Roy V Wright (Ed.) 1912 Locomotive Cyclopedia of American Practice, Third Edition (New York: Simmons-Boardman Publishing Company, 1912), p. 158. (Thanks to Chris Hohl for his 27 February 2018 email noting the engine's fuel capacity.) Works number was 29977 in January 1907.

The owner of this tank engine made cabinets for the Singer sewing machine in South Bend, Indiana.. The 9 was larger than most other 0-4-2Ts delivered to American customers and intended for the standard gauge. The specs call for the tank to be lettered NBSL (something-something-short-line?).
