Suspended trains, also known as monorails, are a type of transportation system where the train is supported and guided by a single rail, typically elevated above the ground. This design allows for efficient travel in urban areas, reducing traffic congestion and minimizing land use. These trains often run on a dedicated track, which can be straight or curved, and are powered by electricity. Suspended trains are known for their smooth rides and can navigate tight spaces, making them suitable for cities with limited room for traditional rail systems.
