Long Bell Lumber Company 2-6-2 "Prairie" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 95 (Locobase 13074)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 30, p. 158. Works numbers were 31151-31152 in June 1907.

Logging railroads throughout the timbering South used the Baldwin design shown here and in several other Locobase entries. Long Bell Lumber put both of these engines to work serving the giant sawmill near Longville, Louisiana; see http://usgwarchives.net/la/calcasieu/block/longville.htm for an account of the construction and operation of this mill. When the mill burned in 1920, LB sent both locomotives to Longview, Washington to serve company interests in the Northwest.
