Newburgh, Dutchess & Connecticut 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 8 / P-2 (Locobase 12148)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p. 228. Works numbers were 14276 in April 1895.

Locobase uses estimates for the heating surface areas (firebox and total) based on very similar values for a nearby locomotive of the Philadelphia, Reading & New England (Locobase 12094). The tubes in the current engine were about an inch longer, the firebox measured an inch deeper in front and in back, and the grate was a bit bigger and this is reflected in the firebox measurement.

Within a decade, the ND & C would be incorporated in the Central New England as 226. In 1913, it would be renumbered 38.

Class 9 / P-2 (Locobase 12624)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 25, p. 88. Works numbers were 21016 in September 1902.

Like other Eight-wheelers procured by this eastern New York and western Connecticut, the 9 was modestly scaled. As such, it was typical of the middle of the pack at the time.

When the ND & C was merged with the Central New England, the 9 was renumbered twice. After a 24-year career, the 39 was scrapped in July 1926.
