Before the opening of Disneyland, a station in the Main Street, U.S.A. section and a station in the Frontierland section were built for the DRR. Main Street, U.S.A. Station, an example of Second Empire-style architecture, was built at the entrance to Disneyland using an original design that incorporated forced perspective elements on its upper levels to make it appear taller. Frontierland Station was built based on the design of the depot building located on the Grizzly Flats Railroad, a full-size narrow-gauge railroad owned by Disney animator Ward Kimball in his backyard. Besides the depot building, the DRR's functioning water tower was also built at Frontierland Station.
