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.

History

The F-8's pulled mostly freight trains throughout their career, with certain ones being rebuilt to give off more tractive effort. They operated on the Great Northern Railroad from 1901. Beginning in 1932 some were scrapped . until the railroad was dieselized in the 1950’s and by 1956 all of them were retired scrapped, except for two 1147 and 1246 preserved from being scrapped.
