New Haven / New York & New England / Philadelphia, Reading & New England 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class G-1 (Locobase 12010)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 17, p. 173. Works numbers were 12380-12381 in December 1891.

The Cincinnati, New Orleans & Texas Pacific contracted for this pair of Vauclain compound Consolidations. Indeed, the specification of the letters "C NO & TP" on the tender. They were to be numbered 604-605.

But the southern railroad contracted buyer's remorse and turned them back in. Baldwin relettered and renumbered the duo and produced them for the New York & New England. The cylinders were smaller than many of the Vauclain compounds then be built and the compounding ratio more in line with later practice in other countries. As with the other Baldwins, the cylinders were fed through 10 1/2" (267 mm) piston valves.

At some later date, the New Haven rebuilt the G-1s as 19" x 26" simple-expansion locomotives. Adopting a longer stroke in these circumstances was relatively unusual. In this case, the driving wheelbase also increased to 16 feet even (a 13"/330 mm stretch).

As simples, the 970 and 971 operated until December 1925 and October 1926, respectively.


Class G-3 (Locobase 14304)

Data from Alco builders card Negative H-137.

These low-drivered Ten-wheelers served local freight needs on New Haven branch lines.


Class G-4-a (Locobase 11443)

Data from "Locomotive Building," The Railroad Gazette, Vol XL, No 18 (10 February 1905), p 45. See also Degolyer, Volume 27, p. 136 (inter alia). Works numbers were

Class G-4-a - 858 (Locobase 12719)

Data from Degolyer, Volume 27, p. 137. Works numbers were 24758 in October 1904 and 24824 in November.

In addition to the large cohort of large passenger Ten-wheelers with simple-expansion cylinders (Locobase 11443), Baldwin supplied 2 Vauclain compounds. These had large 15" piston valves to feed the duplex-cylinder casting on each side.

Both were rebuilt by 1916 with 22" x 26" simple-expansion cylinders. See Locobase 3317 for the result; the 2 ex-compounds were reclassified G-4-b.


Class G-4-a/G-4-b - rebuilt (Locobase 3317)

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

Like the earlier 8-wheelers, about a third of the large class of 1904 10-wheelers were rebuilt beginning in 1926 with steel cabs, 12" piston valves, Baker, Southern, or Walschaert valve gear, new frames, and superheaters. Most ended their days in commuter service, to which they had been moved when the larger Pacifics entered service in the 'teens.

Two wound up on Australia's Commonwealth Railway as Class CA 78 & 79. 78 had Southern valve gear, 79 used Baker gear. 78's Australian career lasted 27 months, when she was written off. 79 lasted until May 1950, when she was written off. Both were scrapped in 1956. http://www.railpage.org.au/comrails/cr_locos/index.html

(Note: the official name for the New Haven was the New York, New Haven, and Hartford and the acronym that appeared on its tenders was NY, NH & H.)


Class P-4 (Locobase 6642)

Data from 1915 CNE 3 - Classification of Locomotives supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 17, p. 183. Works numbers were 12390-12391 in December 1891 and 12412-12413 in January 1892.

One of the treats of compiling Locobase is being introduced to railroads whose existence was hitherto unsuspected. The CNE lay across northern Connecticut from the Poughkeepsie Bridge to Cambell Hall. The wikpedia entry on the Connecticut Western Railroad (http://en.wikipedia.org/wiki/Connecticut_Western_Railroad, visited 30 June 2005) has the details on the various incarnations and combinations this line went through. It was merged with the New Haven in 1926.

These four Ten-wheelers were bought by the line when it was the Philadelphia, Reading & New England, a short-lived interim. The designation appears to be quite basic -- P for passenger, 4 for 4th different design. The CNE Classification book gave an engine wheelbase of 18 ft 9 1/2" (5.73 m), which.seems awfully short. Locobase takes Baldwin's more typical figure. As delivered, the tender's tank held 3,300 US gallons (12,491 litres) of water.

After more than two decades in service, the 26 was retired in 1915, 27 followed in 1916. Ten years later, the 25 (renumbered 47 in 1922) ended service in 1925, and 28 (renumbered 48 in 1922) closed the class in 1926.
