Buffalo, Rochester & Pittsburgh 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class G (Locobase 11656)

Data from Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University Vol 14, p. 6. Works numbers were 8860 in October 1887; 8862-8863 in November.

These Moguls were used as switchers and trailed a slope-back tender as a result.


Class L (Locobase 11665)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 14, p. 96 and Volume 16, p. 196; Birmingham & Northwestern Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange collection. Works numbers were

The BR & P bought this class in ten- and eleven-locomotive orders. If the Birmingham & North Western's 22 (ex-76) is any guide, the BR&P overhauled and modified the class. The tube count (239) and area and grate area remained the same, but firebox heating surface area grew considerably to 193.34 sq ft (17.96 sq m). Arch tubes most likely contributed to the increase. Cylinder volume decreased because of a 1" (25.4 mm) reduction in cylinder diameter. Tender capacity grew to 4,460 US gallons (16,880 litres) of water and 10 tons (9.1 metric tons) of coal.

Much of the class was sold off in 1905-1906 with the rest being scrapped in 1901-1911.

Even an old Mogul was a pretty handy locomotive, as the diversity of new owners of some of the Ls suggests. Illinois main line Alton & Southern took 83. 73-74 went west to Washington State's Spokane International as 11-12. 11 later went to Humbird Lumber of Sandpoint, Idaho while 12 operated on the Oregon California & Eastern headquartered in Klamath Falls, Ore beginning in 1920. After two more decades as the OC&E's #2, the engine ended its working days at Lincoln Sand & Gravel.

76 first went to the Chesterfield & Lancaster as their #1 and later joined the Birmingham & Northwestern as their 22, finishing its days at the Adrian Furnace Company in Dubois, Pa.

79 landed on Colorado's Roaring Fork Railroad and took road number 100. Still farther flung was 82, which sailed up to the Copper River & Northwestern, which ran 196 miles (316 km) from Kennicott, Alaska to Cordova.

Finally, 93 to the far-north James Bay Railway, which was planned to head north from Toronto to James Bay, some 265 miles (427 km) due north. This railway, which had struggled for years with this project, was reorganized in the same year (1905) as the Canadian Northern Ontario Railway (part of the Canadian Northern).
