A suspended train is a type of railway system where the train cars are hung from an overhead track rather than running on tracks laid on the ground. This design allows for efficient travel in urban areas, as it minimizes the need for extensive ground-level infrastructure and can navigate around obstacles like buildings and roads. Suspended trains are often found in cities with limited space, providing a unique solution for public transportation. One well-known example is the Wuppertal Suspension Railway in Germany, which has been in operation since 1901 and showcases the engineering capabilities of this transport method.
