SHORT LINE RAILROAD
Maries River Railroad keeps Idaho’s timber industry rolling, moving thousands of carloads of lumber and logs annually across a 71-mile route in northern Idaho. Since its founding in 1980, STMA has preserved vital rail service for local mills and manufacturers, connecting rural communities to national markets.
Maries River Railroad is classified as a shortline railroad. It operates one of North America's most specialized freight rail networks, connecting businesses across northern Idaho with safe, efficient, and environmentally responsible transportation solutions.
FOUNDING HISTORY & ORGANIZATIONAL STRUCTURE
STMA was founded in 1980 by Potlatch Corporation to maintain rail service for its timber operations after the Milwaukee Road abandoned its Pacific Extension. The railroad’s original purpose was to move raw and finished timber products from local mills to national rail connections.
