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

Class Details by Steve Llanso of Sweat House Media

Class 188/P-2 (Locobase 12076)

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

When they were delivered in 1893, this decade of Consolidations were among the biggest Vauclain compounds in terms of cylinder volume. Their two piston valves (one for each set of 1 HP and 1 LP cylinders) measured 10 1/2" (267 mm) in diameter.

Some time later, the Central New England (which had absorbed the bankrupt NY&NE) 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 incorporated CNE locomotives into its motive-power roster.
