The Duluth, Missabe and Iron Range Railway (DM&IR) (reporting mark DMIR) was a railroad operating in northern Minnesota and Wisconsin to haul iron ore and later taconite to the Great Lakes port of Duluth, Minnesota and Two Harbors, Minnesota. The railway was acquired on May 10, 2004, by Canadian National Railway (CN) when it purchased the assets of Great Lakes Transportation.
The Duluth and Iron Range Rail Road Company (D&IR) Shops near Two Harbors, Minnesota, are representative of the resources required to operate a railroad dedicated to the transportation of iron ore. The shops serviced the rolling stock of the D&IR and, later, the larger entity of the Duluth, Missabe and Iron Range Railway Company. The D&IR was Minnesota's first Iron Range railroad, helping to establish the state as a major iron-producer in the late nineteenth century. Ore pulled from the Vermillion and Mesabi Iron Ranges and transported by the D&IR contributed significantly to the growth of the country.
The GR is the depot at Two Harbors.
