Caption: The Electric Underground (interpretive panel located inside mine tunnel)
Additional Description: This 1919 image shows coal being brought out from Portal 31. Electrical haulage was used in this mine from the very beginning. The trolley ran only along the main haulage road. The 13-ton motor would take empty cars to room headings and collect full cars to be taken outside. As the mine expanded underground the length of the trolley line also grew. Eventually, the electric trolley motors were replaced by battery powered vehicles.
