The Great Northwest Railroad (GRNW) is located in North Central Idaho, and runs a mainline of approximately 77 miles (124 km).
The GRNW interchanges east of Lewiston with the BG&CM Railroad.
Primary commodities of the GRNW are forest products consisting of lumber, bark, paper and tissue; agricultural products, industrial and farm chemicals, scrap iron and frozen vegetables.
The Camas Prairie Railroad Company was formed in 1909, jointly owned and operated by the Northern Pacific Railway (later BNSF), and the Oregon Railroad & Navigation Company (later Union Pacific).
In 1909, the two major carriers joined forces and the Camas Prairie Railroad was born.
