Main Street Vehicles are attractions at several Disney Parks. All vehicles that are found on Main Street were designed to accurately reflect turn-of-the-century vehicles, including a double-decker bus, a horse-drawn streetcar, a fire engine, and an automobile. They are available for one-way rides along Main Street, U.S.A. The horseless carriages are modeled after cars built in 1903. They are two-cylinder, four-horsepower (3 kW) engines with manual transmission and steering. Walt Disney used to drive the fire engine around the park before it opened, on most mornings. It has also been used to host celebrity guests and used in the parades. The vehicles close for the day once Main Street becomes too crowded for vehicles to safely operate.
