Great Northwest Railroad Company GRNW #339

Nature of Firm

The GRNW operates freight service from a connection with UP and BNSF at Ayer Junction, WA to Riparia, WA (15.1 miles), via trackage rights over UP, and then 72 miles to Lewiston, ID. Traffic includes forest products, agricultural products, industrial and farm chemicals, scrap iron and frozen vegetables.


The Camas Prairie Railroad Company was formed in 1909 by the Northern Pacific Railroad (now BNSF), the Oregon Washington Railroad and Navigation Company (now UP). The railroad was operated jointly until April 18, 1998, when BNSF and UP sold their interests in the CP to a new short line, Camas Prairie Railnet. In 2000, CSP abandoned the 67 mile branch line from Spalding, ID to Grangeville, ID. Watco Companies purchased the line in 2004, renaming it the GRNW. In December 2004, GRNW abandoned a 28 mile branch line from Orofino, ID to Jaype, ID. In 2005, Watco sold the 75 mile Kooskia Branch to the Bountiful Grain & Craig Mountain Railroad.
