Central Vermont / Detroit & Toledo Shore Line / Duluth, Rainy Lake & Winnipeg 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 13617)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 27, p. 60. Works numbers were 24173-24174, 24196, 24203, 24214, 24224 in May 1904.

Locobase 9069 shows the Grand Trunk's compounds of the same year. The Shore Line's Moguls had a longer stroke and eight fewer tubes.

The TStL rebuilt the class as simple-expansion, superheated engines. 1 and 6 were scrapped in 1929 and 2-5 in 1934.


Class D-12-a (Locobase 7977)

Data from CN to 1953 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 26261-26263 in November 1902.

A trio of Moguls for the western Canadian prairies. Purchased by the railway that would be better known after 1908 as the Duluth, Winnipeg & Pacific. Even with that name, the railway didn't connect directly to Winnipeg, let alone the Pacific Ocean. Its Canadian terminus, Fort Frances, Ontario, met the Canadian Northern mainline.


Class D-2a (Locobase 11881)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 13, p. See also CV 1 - 1929 List of Locomotives supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 8556-8557 in June 1887; 8659-8662, 8667 in July.

All served the CV for almost forty years. Six were scrapped in the mid-to-late 1920s. 315 was retrofitted with a new boiler by Alco in 1921. The vessel was pressed to 160 psi and held 246 tubes. This rejuvenation delayed the 315's retirement and scrapping until June 1934.


Class unknown (Locobase 7984)

Data from CN to 1953 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Volume 29, pp. 170+. Works numbers included 32047 in October 1907 and 32199 in November.

Very similar to most other Grand Trunk Moguls, these four went to the D&TSL. The specs show a tender that weighed 120,000 lb (54,431 kg)

Apparently they were never superheated before they were scrapped in 1929.
