Layout
The 3 ft (914 mm) narrow gauge track (North America's most common narrow gauge) is laid in a continuous circuit around the park. (The park's publicly accessible areas were extended beyond the track's perimeter with the construction of Mickey's Toontown.) The line features several bridges, grade crossings, including one for parade floats east of "It's a small world" which doubles as access to the service track, yard and roundhouse for locomotive and train storage and maintenance, located backstage beneath the monorail roundhouse. The line previously featured automatic block signals, but they are no longer in use. The service road is protected by two miniature wigwag crossing signals. The Santa Fe Railway offered the use of full-scale crossing signals, but Disney declined as they would be out of scale with the trains. These scaled-down replicas were designed and built by the Santa Fe Railway San Bernardino shops as a gift to Disneyland. They operate with automotive windshield wiper motors.
