A monorail is a type of train that runs on a single track, which is usually elevated above the ground. This design allows it to travel smoothly and efficiently, often in busy urban areas where space is limited. Monorails are known for their sleek appearance and can be a fun way to see a city from above. Many cities around the world, like Tokyo and Las Vegas, have implemented monorails as a form of public transportation. They are often quieter and less polluting than traditional trains, making them an eco-friendly option. Monorails can also be a popular attraction in places like theme parks, providing a unique ride experience.
