Main Street Vehicles is a series of turn-of-the-20th-century-style vehicle attractions in Disney theme parks throughout the world, consisting of 3 ft narrow gauge tramways with horse-drawn streetcars and free-roaming motor vehicles. They usually operate in their respective Main Street, U.S.A. sections, transporting park guests on one-way trips between the Town Square at the park's entrance and the Central Plaza at the park's center.
