The extension cables were used in the pit near the loading shovels. Since tracks were moved frequently as mining progressed, that saved setting up and moving the overhead wires.
The 2 Oliver operations with very small locos weren't for moving iron ore, they were for disposing of rock separated from the ore at the crushing plant.
The Cleveland Cliffs operation at the Hill Trumbull mine had a problem with thief of the overhead electric wire in the later years wire was stolen for the copper and sold by the thieves to scrap dealers in Duluth and the Twin Cities the thief would take place during the winter months when mining activities would cease !
