Monorail

A monorail is a type of train that runs on a single, elevated track, usually made of a metal beam. Unlike traditional trains on multiple rails, a monorail is supported by and guides along its central beam, often suspended above city streets or over difficult terrain. This design allows for quiet, efficient transit with minimal ground footprint, making it suitable for urban environments. Monorails are often used in airports, amusement parks, and some city transit systems because they can navigate tight spaces and provide smooth, elevated transportation.
