👉 A tranvia is a type of underground railway system that connects different parts of a city or town. It typically consists of several trains, each with its own tracks and platforms, allowing passengers to travel between these sections of the train. Trains in a tranvia are often designed for efficiency and reliability, with features such as automatic switching systems, track sensors, and emergency stops. Transvia systems can be found in many cities around the world, including New York City, Tokyo, and Seoul.
