In 1949, Walt Disney, with help from Disney Studios' Roger Broggie, built the one-eighth scale Lilly Belle steam engine for Walt's backyard railroad. The Lilly Belle was named for Walt's wife Lillian, and was the centerpiece of a rail system that included  more than 2,600 feet of track, a 46 foot trestle and a 90 foot tunnel. Disney named his backyard railroad, the Carolwood Pacific Railroad. It was named for Carolwood Drive in Holmby Hills, where the Disney home was located.

Note: When Roger Broggie and the Disney Studios Machine Shop began planning to build the No. 1 and No. 2 engines for Walt's new Disneyland theme park, the two locomotives were patterned after the scaled down Lilly Belle. The No. 1 C.K. Holliday and No. 2 E.P. Ripley are almost identical, except for the differing smokestacks and pilots.
