The railroads were a major feature of the industrial and mining economy of the Copper Country. They carried the ore from the mines to the mills all over the Peninsula. But they also linked the bustling mining district with industrial America. The principal transportation link between Calumet and the rest of the US was this station, where for many decades the train left for Chicago every night, arriving in the am. The industrial and labor leaders came here through this station. And many of the immigrants who migrated to the Copper Country from Europe, left on these trains for life elsewhere in industrial America.
