New York & New England 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 189 / P-2 (Locobase 12076)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 18, p. 256. Works numbers were 13761-13762, 13764-13765, 13769, 13772-13773, 13775, 13778 in September 1893; 13790 in October.

These were among the biggest Vauclain compounds in terms of cylinder volume. Some time later, the Central New England (which had absorbed the bankrupt NY & NE) was to become in 1896) removed the compound cylinders and replaced them with two 20" x 26" simple-expansion cylinders. Designated P-2s, the class was retired in 1924-1925, just before the New Haven incpororated CNE locomotives into its motive-power roster.
