New York, New Haven & Hartford 2-6-0 "Mogul" Locomotives in the USA

Class K-1-a (Locobase 5870)

Data from "Schenectady Mogul Freight Locomotive", Railway Age, Volume 22 (26 October 1896), p 273. Works numbers were 4461-4470 in July 1896, 4673-4682 in January 1898, 5422-5433 in May 1900, 5434-5440 in June, 5441-5445 in July, 5446 in August.

Preceding the large K-1 class described in Locobase 813 were these ten trial horses. Clearly, John Henney, the NY,NH & H's Superintendent of Motive Power was satisfied with the design delivered by Schenectady. The K-1s that followed four years later (Locobase 813) were almost identical except for having tubes 2 inches longer.

Class K-1-b/K-1-c (Locobase 813)

Data from NH 1962 Steam Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Volume 28, p. 24.

From 1900 to 1907, the New Haven bought almost 200 of this Mogul design from three works. In order of their appearance, the batches came from:

Builder Works numbers Road numbers

Schenectady 5422-5446 in 1900 511-535

Alco-Rhode Island 25600-25609 in May 1902 551-560

Alco-Rhode Island 29191-29195 in October 1903 881-885

Alco-Rhode Island 27027-27041, 29364-29378

in January 1904 561-575, 886-900

Alco-Rhode Island 28877-28896 in November 1904 576-595

Alco-Schenectady 31008-31047 in May 1905 326-349, 420-434

Alco-Cooke 43135-43149 in April 1907 285-299

Baldwin's works numbers were assigned on the production line, not at time of order, so they are not continuous.

In 1905, the Philadelphia builder delivered works numbers

25334-25335, 25347-25348, 25377, 25401-25403, 25427 in March;

25450-25451, 25461, 25489, 25491-25492, 25505, 25540-25541, 25553-25554 in April;

25603-25604, 25625, 25638, 25658-25660, 25662, 25683-25684, 25690-25691, 25714-25715, 25728 in May;

25790-25791, 25798-25799, 25846, 25881-25882, 25890, 25932 in June;

25963 in July.

Road numbers were 438-479

In 1907, Baldwin had opened its new Eddystone, Pa plant near the Delaware River. Works numbers for the Moguls produced for the New Haven were:

30908, 30963 in May;

31001, 31020-31021, 31043, 31057-31059, 31080-31081, 31099,31162-31163, 31176 in June; 31190-31194, 31227, 31256, 31342, 31360; in July;

31450 in August

All seem to have had 15 sq ft (1.39 sq m) of arch tubes contributing to direct heating surface. Boiler pressure increased slightly over the K-1-a (Locobase 5870)..

They were delivered with Stephenson gear, but were superheated in 1913; see Locobase 8117.

Class K-1-d (Locobase 8117)

Data from NH 1962 Steam Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

Locobase 813 shows the large class of Moguls delivered to the New Haven as main-line freight engines. Obviously this arrangement, while of decreasing value as a fast freight engine running ahead of the passenger trains, proved highly useful in all kinds of local freight, passenger, even commuter work. So the New Haven removed 137 small tubes in favor of 21 large flues holding a modest amount of superheater area and the cylinders increased 2" (50.8 mm) in diameter. Walschaert, Baker, and Southern valve gear was fitted depending on sub-class. So compact was the 2-6-0 arrangement that the Southern gear (a radial gear similar to a Baker layout) looks oddly placed outside of the second driving axle.

As so refitted, these Moguls lasted a long time, some running as late as 1951, because they could run freights fast enough on passenger lines to avoid clogging up the road.
