On a business trip to Chicago in the late-1940s, Disney drew sketches of his ideas for an amusement park where he envisioned his employees spending time with their children. The idea for a children's theme park came after a visit to Children's Fairyland in Oakland, California. It also said that Disney may have been inspired to create Disneyland in the park Republic of the Children located in Manuel B. Gonnet, La Plata, Argentina, and opened in 1951.[92] This plan was originally intended to be built on a plot located across the street to the south of the studio. These original ideas developed into a concept for a larger enterprise that would become Disneyland. Disney spent five years developing Disneyland and created a new subsidiary company, WED Enterprises, to carry out planning and production of the park. A small group of Disney studio employees joined the Disneyland development project as engineers and planners, and were dubbed Imagineers.[citation needed]
As Disney explained one of his earliest plans to Herb Ryman, who created the first aerial drawing of Disneyland presented to the Bank of America during fund raising for the project, he said, "Herbie, I just want it to look like nothing else in the world. And it should be surrounded by a train."[93] Entertaining his daughters and their friends in his backyard and taking them for rides on his Carolwood Pacific Railroad had inspired Disney to include a railroad in the plans for Disneyland.
