Before being delivered it was put on display at the New York World's Fair in 1940. After the Fair, the locomotive was sold to the Hammermill Paper Company in Erie, PA, as #4, but its 190,000 lb weight proved to heavy for Hammermill's tracks.
In 1941, it was therefore sold to the Pennsylvania Power & Light Company and renumbered #4094-D. No. 4094-D switched coal hopper cars at the company's Hauto, PA, plant until 1969, when it was donated and moved to the Railroad Museum of Pennsylvania. By then, it was liveried in black and gold but, during restoration many years later, the museum uncovered the original sky blue livery #4094-D sported during its time working for Pennsylvania Power & Light.
It is now on static display at the Railroad Museum of Pennsylvania, beautifully restored and indoors.
