Nos. 2101, 2107 and 2120 were assigned to the Mesabi Division for ore train service on August 20, 1951. However, they would soon be replaced by diesel locomotives and retirement started on January 31, 1950. By May 1958, all the Q-1s were retired.DispositionNone of the Q-1s have been preserved all 30 locomotives were replaced by new Diesel Locomotives that replaced them pulling freight trains in 1950 and 1958.
