Denver & Great Western 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 11498)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 26, p. 246. Works number was 23773 in February 1904.

See Locobase 4811 for a description of this Colorado sugar-beet railway.

This low-numbered Consolidation never strayed from the GW. Its scrapping came almost 50 years later in March 1951.


Class 2 (Locobase 11499)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 26, p. 246. Works number was 26267 in August 1905.

See Locobase 4811 for a description of this Colorado sugar-beet railway. The 2 was in every way a considerable step up in power and flexibility. The taller drivers allowed more speed (although clearly a relative advantage) while the larger boiler and grate together with the larger cylinder volume led to increases in tractive power and steaming capacity.

The 2 was scrapped in March 1951.
