Central of New Jersey 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Inspection engine (Locobase 12676)

Data from Baldwin Locomotive Works datacard as digitized by the DeGolyer Library of Southern Methodist University, Volume 25, p. 263. See also "More Recent Baldwin Locomotives," Daily Railway Age, Volume XXXV, No 25a (24 June 1903), pp. 1062-1063. Works number was 22132 in May 1903.

Like several other inspection engines, the 900 had a car body built by Wilmington, Delaware's Jackson & Sharp. Its boiler was set quite low to offer more room to the inspectors riding in the coach-like car body that straddled it. Anthracite coal burned in a long narrow grate reduced smoke. Its cylinder dimensions changed twice, first to 16"x 20", then to 15" x 20" (the latter in February 1920).
