Carolwood Pacific Railroad, Miniature railroad in Holmby Hills, Los Angeles, US

The Carolwood Pacific Railroad was a private miniature railway in the garden of a residence in Holmby Hills, Los Angeles, with a track length of 797 meters (approximately 0.5 miles). The rails ran through handmade tunnels, over wooden bridges, and along landscaped garden beds around the property.

Walt Disney built the railway on his property in 1949 and tested the steam locomotive Lilly Belle for the first time on December 24 of that year. His experience with this private line later shaped the design of train attractions at Disneyland Park.

The initials CPRR matched those of the Central Pacific, one of the railroads that completed the first transcontinental line in 1869. Disney named the line after his address at 355 Carolwood Drive. Articles in magazines such as Look in September 1951 drew interested visitors to the house, and Disney invited them to ride and sometimes drive the train.

The railway operated at a 1:8 scale with a working steam engine pulling freight cars and a caboose behind the locomotive. Many components were crafted in the Walt Disney Studios workshop and assembled on the property.

An S-shaped tunnel runs beneath Lillian Disney's flower garden, allowing the track layout to respect residential landscaping preferences. This design shows how technical hobby and domestic garden planning could coexist in the same outdoor space.
