Louisiana & Pacific 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 250 (Locobase 13451)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 53, p. 353. Works numbers were 30892 in May 1907, 32203 in November 1907, and 44235 in October 1916.

These small oil-burning Consolidations served elements of the Long Bell Lumber Company. 251 originally was numbered 51 by the Calcasieu Long Leaf Lumber Company. After service under the L & P herald, Long Bell moved the engine by March 1927 to Ryderwood, Wash and renumbered 671.

The railroad sold the 252 to Mount Hope Mining Co of Longview, Washington as their #3. The Mount Hope soon sold the 3 to the Longview Portland & Northern, which renumbered it 680. Then the LP & N let the 680 go to the Willamina & Grande Ronde in Oregon on what must have been a long-term loan because the engine returned to the LP & N and regained its number.

In July 1977, Robert Gray bought the engine to operate on the Virginia & Truckee as their #29.
