Duluth, South Shore, & Atlantic 2-8-0 "Consolidation" Locomotives in the USA

Class F (Locobase 1323)

Data from DeGolyer, Volume 29, p. 272. See also []. Works numbers was 30179 in 1907.

Built as an 0-8-0 switcher for use at the ore docks in Marquette. Modified as a solo 2-8-0, it differed from the six Consolidations delivered by Baldwin (Locobase 1332) in having smaller drivers, cylinders 1" (25.4 mm) larger, slightly larger grate but smaller firebox, and fewer boiler tubes.

Scrapped in November 1937.

Class F-1 (Locobase 1332)

Data from ([]) and from

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p 113. Works numbers 32246, 32275-32276, 32300 in November 1907; 32334, 32365 in December.

All went to the ferro-knacker in the 1930s. 605 led the disposals in July 1935, followed by 601 in September, 602 in October 1936, 603 in December, 604 in October 1937, and completed by 600 in November.

Class F-2 (Locobase 1333)

Alco-Brooks delivered 30 locomotives with 19 1/2" (495 mm) cylinders and 31,733-lb TE to the Detroit Southern (Locobase 6925), but financial troubles for successor Detroit, Toledo & Ironton led to the sale of all but four to other railroad.

116 & 107 went to the DSS&A, possibly after they were rebored to 20 x 28 in 1910.

After almost 30 years, the DSS&A scrapped the 607 in 1939 and sold the 606 to Ford Motor Company in 1941.

Class F-3 (Locobase 1334)

Data from DSS&A 1-1944 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also ([]). Works numbers were 53576-53590 in June 1913.

Biggest Consolidations on the line; most out of service by 1950. Canada's Western Dominion Coal of Taylorton, Saskatchewan bought the 706 in August 1946 and operated it until it was scrapped 1961.

Class F-4 (Locobase 6668)

Data from DSS&A 1-1944 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 65966-65967 in November 1924.

These Consolidations, delivered after the First World War, outdid the F-3 (Locobase 1334) by wringing more tractive effort out the same boiler using a higher boiler pressure and more superheating surface. On the other hand, the ratio of boiler to cylinder suggest a system that would lose steam relatively soon into a continuous effort.
