On March 31, 1958, the No. 3 locomotive participated in the inauguration ceremony for the DRR's Grand Canyon Diorama, which features a foreground with several lifelike animals, a background painted by artist Delmer J. Yoakum on a single piece of seamless canvas measuring long by high, and musical accompaniment from Ferde Grofé's "Grand Canyon Suite". Located inside a tunnel on the DRR's route, the diorama was claimed by Disneyland to be the longest in the world, and during its inauguration it was blessed by Chief Nevangnewa, a 96-year-old Hopi chief. The diorama cost over $367,000 and took 80,000 labor hours to construct.
