[2] Disney ran his 1/8 scale steam train Lilly Belle (named for his wife) along the Carolwood Pacific's 2,615 feet of track for three years (1950–1953).

[5] Diane and Disney historian Michael Broggie entered into an agreement with the city of Los Angeles and the Los Angeles Live Steamers Railroad Museum to have the barn rebuilt on the LALSRM property in Griffith Park as a museum dedicated to Disney's love of trains and the impact trains had on his life and work.

[5] Renamed Walt Disney's Carolwood Barn, the museum was dedicated on July 18, 1999 by Diane and members of the extended Disney family, as well as local politicians such as president of the LA Parks & Recreation Commission Steve Soboroff and special assistant to Mayor Richard Riordan (and future LA city councilman) Tom LaBonge.

In May of 2008, a miniature railroad depot that was originally part of Disney animator Ollie Johnston's backyard layout, was moved to the barn and restored for display.

"[11] The barn operates independently of the rest of the Los Angeles Live Steamers complex and has its own entrance located on the eastern end of the property off of Zoo Drive.

Inside the barn are displays telling the story of Walt Disney's connection to trains through his life and his work—including photographs and original artifacts like an actual CPRR car.

There are also displays dedicated to animators Ward Kimball and Ollie Johnston, who were responsible for rejuvenating Disney's interest in model railroads in the late 1940s.

Beyond the barn are the souvenir stand, steam plant (operated by LALSRM members), Ollie Johnston Depot, and combine car pavilion.

The pavilion houses not just the combine car, but also an exhibit about the history of the Disneyland Railroad and other train-related attractions at the Disney theme parks.

Notable guests have included Bobby Burgess, Margaret Kerry, Floyd Norman, Tony Baxter, Rolly Crump, Harriet Burns, and Alice Davis.
