Mississippi Eastern 2-6-0 "Mogul" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 7 (Locobase 14306)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 62, pp. 364+, See also Locobase 14343 for more on the Mississippi Eastern. Works number was 53233 in May 1920.

Typical logging Mogul, but without the cabbage stack because it burned coal.

When Long Bell's Mississippi timberland had been cut over and the railroad closed, the 7 was sold to the Murfreesboro-Nashville in Arkansas.
