The Great Northern F-8 is a class of 125 2-8-0 "Consolidation" type steam locomotives built by the Rogers Locomotive and Machine Works, their corporate successor the American Locomotive Company, and Baldwin Locomotive Works between 1901 and 1907 and operated by the Great Northern Railway until the mid 1950s. They operated throughout the Great Northern pulling freight trains with some being rebuilt with larger cylinders and higher boiler pressure, giving them more tractive effort. Retirement of the F-8s started as early as 1932, but some would last and continue to pull freight until 1956, when the last F-8 was retired.
