In the 1940s, the Duluth, Missabe and Iron Range Railway (DM&IR) was in the troubles of World War II, so in response to this issue, the Baldwin Locomotive Works decided to draw up plans for a 2-8-8-4 Yellowstone, the end result was the DM&IR Yellowstones, there were 18 of them built, with two classifications given to them when built, the first eight were built in 1941 and were classified as "M-3", an additional ten were built in 1943 and were classified as "M-4".
Retirement of the Yellowstones had commenced between 1958-1963, and although all were retired from active service, three examples of the DM&IR Yellowstones have survived into preservation, and those three surviving examples are Nos. 225, 227, and 229.
