Paine Lumber Company 2-6-2 "Prairie" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 13031)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 25, p. 259. See also http://www.wisconsinhistory.org/hp/register/viewSummary.asp?refnum=86001392 for information on the Paine Lumber Company Historic District in Oshkosh. Works number was 29627 in November 1906.

Edward L Paine began logging in Wisconsin in 1853 and his sons would carry the business into the 20th Century as a major timber supplier based in Oshkosh. In the mid-1920s the company was still prosperous to erect workers' housing and an accompanying Paine Thrift Bank, which functioned something like a credit union.

This Prairie only operated for Paine for about 15 years before being sold to Langlade Lumber in 1919.
