Marquette & Western 2-6-0 "Mogul" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class D (Locobase 1325)

Data from http:/fp-www.wwnet.net/`dulong/dssa/locomot.thm. Works numbers were 7151, 7154, 7165-7166, 7189 in February 1884. Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University Volume 12, p. 24.

Small, low-drivered freight locomotives sold originally to the Marquette & Ishpeming Construction Company to support the building of the M & W, which soon became the Marquette, Houghton & Ontonagon, which was then leased to the Duluth, South Shore & Atlantic in 1886 and finally purchased in 1890. (According to the Baldwin Specs page, however, the M & I CC purchase was for the Detroit, Mackinac & Marquette Railroad.)

All sold to lumber companies (Menasha Wooden Ware, Christiansen, and Thompsen Wells) in 1925-1926.
