A monorail system is a type of transportation that runs on a single rail, typically elevated above the ground. This design allows for efficient travel in urban areas, reducing traffic congestion and minimizing land use. Monorails are often used in theme parks, cities, and airports to provide quick and convenient transit options. Monorails can be powered by electricity, making them an environmentally friendly choice compared to traditional buses or cars. They are known for their smooth ride and ability to navigate tight spaces, which makes them suitable for densely populated areas. Examples of monorail systems include the Seattle Center Monorail and the Tokyo Monorail.
