Begun as the Legionnaire in 1925, the train was renamed the Minnesotan in 1930, and was powered by a 4-6-2 Pacific-type locomotive. The Minnesotan was one of the finest passenger trains the Great Western operated but could not compete against the more famous passenger trains of the Milwaukee Road and the Chicago and North Western.
The Great Western dropped the name on May 10, 1949, but Chicago to St. Paul passenger service continued to linger on for seven more years. By the early 1950s, a doodlebug or (later) a single EMD F-unit pulled a railway post office car, a baggage car, and a coach. This service was spartan compared to the Minnesotan of less than a decade earlier, and ceased entirely on August 11, 1956.
