The 470 was built to handle the heavy 10 or 12 car passenger trains between Portland and Bangor. She operated on such trains as the "Flying Yankee", "Pine Tree Limited", "Bar Harbor Express". "The Kennebec", "State of Maine Express" and the "Gull", an overnight Boston to St. John, New Brunswick train. The 470 also hauled trains on the Portland to Boston route over the Boston & Maine RR when the two roads were under joint management. It was not uncommon to see the 470 and other Maine Central locomotives at North Station in Boston during the period 1932 to 1953.
