Southern Manitoba Railway (reporting mark SMNR) was incorporated in July 1999 in Winnipeg, Manitoba, Canada. The railway was 80 miles (128 kilometers) long and provides transportation for the movement of grain and grain products. SMNR interchanged traffic with the Canadian National Railway at Morris, Manitoba. The railway originally consisted of three ex CN subdivisions, the Miami (60 miles), Carman (40 miles) and Hartney (41 miles) subdivisions. The Hartney subdivision and a portion of the Carman subdivision was abandoned and removed before 2007.
