Norfolk & Western / Virginia-Carolina Railway 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 1 / F (Locobase 11848)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 13, p 76. Baldwin works numbers were 8031, 8035, 8037, 8040, 8043 in July 1886; 8442-8443, 8455-8456, 8459 in March 1887; 8467 in April; 8578-8579, 8582-8583 in May; 8607-8608 in June.

A couple of points to notice about this relatively large batch of Consolidations: at the grate level, the firebox is wider than the frame. In this period, most locomotives retained the deep firebox between the frames, which meant an average width of 33-34 inches. This firebox measured 42" across, which meant it had to sit above the drivers, not between them. [Later N & W documents would describe the firebox as "narrow".] Also, the safety valves were sealed and set at 140 psi, a little higher than the usual as well.

Most of the class was retired in the mid-teens.


Class 2 / F (Locobase 12917)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 235. Works number was 27417 in February 1906 and 33025 in November 1908.


Class 61 (Locobase 12699)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 27, 10. Works number was 23999 in March 1904.

How unusual was it for Baldwin to offer a cross-compound locomotive; among the few produced was the B-class set for the Norfolk & Western in 1898 (Locobase 3197). And to manufacture a 10th engine and display it at the 1904 Louisiana Purchase Exhibition was an odd choice. Each of the two unequal-size cylinders had its own slide valve and steam from the HP cylinder took the usual route through a receiver at the front end before entering the LP cylinder.

It remained a cross-compound for only a short time before being converted to a simple-expansion 21" x 32" B-class Consolidation. It was scrapped in 1934.


Class B (Locobase 3197)

Data from 1929 Norfolk & Western locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Raildata collection. (McShane (1899) also has details on this class, but does not include the boiler pressure.) See also DeGolyer , Volume 21, p. 139 and Volume 22, p. 291. Works numbers were 15746-15748 in February 1898, 15773-15775 in March, 16215 in September, and 17593-17594 in March 1900.

The Baldwin specifications sheet had some exacting requirements for this set of cross-compounds: "Guaranteed to develop tractive power up to the limit of adhesion while working at full stroke on 2.2% grade and to render thoroughly satisfactory service. Working of intercepting valve [to admit live steam to the LP cylinder when needed] guaranteed to be entirely satisfactory and to be protected against any royalties therefor."

According to http://www.trainweb.org/railmaster/nw_rost.html (visited April 2003), this class was later simpled to two 21" x 32" cylinders and given piston valves.

Except for 62, which was scrapped in October 1933, all were were scrapped in July 1934.


Class G (Locobase 3137)

Data from 1929 N & W locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Baldwin's works numbers were 11581, 11583, 11587, 11607, 11609-11613, 11646 in February 1891; 12132-12137, 12140, 12144, 12147, 12158, 12160 in August 1891.

This very large class of Consolidations first entered N & W service when Rogers delivered the first batch in January of 1889. Richmond and Baldwin also supplied Gs over the next few years, the last arriving in 1893.


Class G1 (Locobase 7821)

Data from N&W 3-1955 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

This small batch of Consolidations was overshadowed by the Gs profiled in Locobase 317. But they represented a definite power upgrade with higher boiler pressure and more boiler heating surface on the same running gear.


Class T (Locobase 12067)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 18, p. 168. Works numbers were 13274, 13278-13279, 13286-13287, 13290-13292, 13294, 13296; 13326-13328,

13332-13333, 13335 in March 1893; 13343, 13347-13348 in April; 13419 in May; 13562 in July; 13948-13956 in March 1894; and 13964 in April.

All of these were delivered as Vauclain compounds and all had Belpaire fireboxes. They retained the Belpaire fireboxes, but soon discarded the compounding setup in favor of relatively short stroke 21" x 24" simple-expansion cylinders.


Class W/W1 (Locobase 12314)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 22, p. 20. The class was divided between two builders. Baldwin supplied 800-829 and 845-854 (works numbers were 16350-16359 in November 1898, 16590-16594 in March 1899, 16673-16677 in April, 16771-16774 in May, 16823-16824, 16856-16859 in June.) Richmond supplied 830-844 and 855-864.

All of this class of Consolidations were rebuilt as W1s. In the 1920s, the following engines were recast as 0-8-0T tank-engine switchers: 800, 802, 804, 806, 809, 821, 825.

Most of the rest were scrapped in the late 1920s, but several enjoyed second careers on other Southern roads. 847 was sold in March 1924 to the Blackwood Coal & Coke Company. 808 was sold in July 1925 to the High Point, Thomasville & Denton. Martin Iron & Steel Company bought the 814 in October 1926, the same month the 847 joined the Norton & Northern -- a shortline operating in Virginia's Yellow Creek Valley and connecting Norton to Wise -- and 849 went to HM Waugh. In August 1927, the N & W sold the 828 to the East Tennessee & Western North Carolina.

812 and 849 went to the Chesapeake Western as their #108 and 107 through dealer H M Waugh in 1929.


Class W2 (Locobase 7823)

Data from N & W 3-1955 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also Angus Sinclair, Railway & Locomotive Engineer, May 1902, pp. 195-196. Baldwin works numbers for its share:

Alco's Cooke and Richmond works, Baldwin, and the N&W's own modern facility at Roanoke contributed to this large class of Consolidations. They were quite representative of turn-of -the-century locomotives - saturated boiler, piston valves, long stroke, and a wide firebox.

R & LE reported that "These engines have given excellent service, and are good steamers ...They will pull 1,100 tons up a 61-ft foot grade (1.2%) with moderate curvature."

Most of the class remained essentially unchanged throughout their long careers. Their tenders grew to hold 9,000 US gallons of water and 14 tons of coal. Scrapping began in the 1920s and had encompassed most of the class by the middle 1930s, but a few persisted until the 1950s.

NB: The Baldwin Specification book Volume 27, pp. 210-211 and Volume 28 show orders for road numbers 722-728, 708-714, 948-949, 673-681 with smaller boilers. By reducing the tube count by 60 to 213, the tube heating surface dropped to 1,694 sq ft and total evaporative heating surface down to 1,824 sq ft. None of the later N & W books of diagrams or classification (1912, 1929, e.g.) show any such subclass.)
