Central New England & Western 4-4-0 "American" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class F/P-3 (Locobase 6643)

Data from 1915 CNE locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Volume 14, p. 179 and Volume 16, p. 139. Works numbers were 9571-9572 in October 1888 and 11208 in September 1890.

The earlier of the two orders recorded in the DeGolyer collection of Baldwin specifications books shows that the CNE&W pair were originally intended for the Richmond, Fredericksburg & Potomac as part of a bundle of standard Eight-wheelers bound for other southeastern US railroads. Four others went to the Atlantic Coast Line, two for the Richmond & Petersburg, and one for the Petersburg. The Yankee engines operated first for the Hudson Connection.

Notes in the 1888 specs suggest a general desire for sturdier construction. Specific instructions called for an adhesion weight of "fully 60,000 lb", I-section side rods with solid ends bushed, bushings at all points in the valve motion, and wagon top sheets and back of boiler made 1/16" thicker than before. The 1890 engine duplicated the design with a further requirement for a "stronger steam chest."

The CNE&W soon was reorganized as the Philadelphia Reading & New England (1892) and later as the Central New England (1899). Although they were renumbered several times and their tenders bore several sets of letters during their 25+ years of service, all three locomotives were sold for scrap by the CNE. First 32 then 31 went for $300 each in April and December, 1915, respectively. 33 was sold for $400 in September 1919.
