History

When the Great Northern received the locomotives, they hauled freight across the system and were rated at pulling 3,000 tons between Whitefish, Montana and Shelby, Montana.[1] Nos. 2101, 2107 and 2120 were assigned to the Mesabi Division ore-steaming on August 20, 1951. However, they would soon be replaced by diesel locomotives and retirement started on January 31, 1950. By May 1958, all have been retired.[2]

Disposition
