Newburgh, Dutchess & Connecticut 4-4-2 "Atlantic" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 10 / P-2 (Locobase 10769)

Data from Baldwin Locomotive Works, Record of Recent Construction ((1903), No. 31, p. 11. Works number was 19461. See [] for a history of the N, D & C.

Originally opened in 1866 as the Dutchess & Columbia, which soon connected Fishkill with the Connecticut Western. A variety of relationships with other railroads didn't keep the D & C from entering bankruptcy in 1874 and the N, D & C emerged in 1877.

Given the relatively light rail on which it ran, this Atlantic design is appropriately sized. It was perhaps the lightest 4-4-2 to run on North American standard gauge and was a repeat of the 1899 New York, Philadelphia & Norfolk pair described in Locobase 12355. In many ways, it resembled a long-wheelbase Eight-wheeler.

The New Haven acquired the N, D & C in 1904 and merged it with the Central New England Railway in 1907. The CNE designated this little Atlantic P-2 and numbered it 228. In 1913, it renumbered it 40. After a 25-year operating life, the 40 was withdrawn in July 1927 and scrapped.
