Built by the American Locomotive Company (ALCO), this 4-8-4 Hudson type locomotive was originally used in heavy passenger service until 1947 when the Nickel Plate Road converted to diesels. It went to light freight and extra passenger service. Altogether this locomotive traveled over 2,000,000 miles which is equivalent to 80 trips around the world. It weighs 536,000 pounds, has 74 inch driver wheels, 25x26 inch cylinders and has a tractive effort of 42,000 pounds. The smoke deflectors on the front along the smoke box, often called "elephant ears", lift the smoke over the cab and out of the faces of the crew. Number 170 was donated in 1957 by the Nickel Plate Road.
