Weighing more than a million pounds and supported by a massive set of trucks (34 wheels), the Challenger Class of locomotives were among the largest and most powerful steam engines ever produced. Used to haul perishables and livestock across the Midwest, the Union Pacific fleet remained in service a short time after World War II. When diesel and gas turbine powered engines were pushed to the limits in 1957, the steam engine fleet was called back into service for a brief period.
