Hanna Mining Company No. 307

No. 307, constructed by General Electric in 1928, is typical of the many 60-ton steeple- cab electric locomotives formerly used in mining and industrial railroad operations. It is the last electric locomotive that operated on the Mesabi Range. Built originally for use at Hanna’s Wabigon Mine at Buhl, Minnesota, it later worked on the Mesabi Chief Washing Plant haulage line near Keewatin. Electrical power was received by means of unusual offset type pantographs which provided clearance necessary for shovel loading of trains in the pits. When No. 307 reached the end of the line, a cord from its huge front mounted disk, working like an extension cord, allowed the engine to travel further into the mine. The locomotive was donated to the Museum by the Hanna Mining Company in 1974.
