Urban rail refers to a system of trains that operate within city areas, providing public transportation to residents and visitors. This mode of transport includes various types, such as subways, trams, and light rail, designed to efficiently move people across short to medium distances. Urban rail systems help reduce traffic congestion and pollution by offering a reliable alternative to cars. These systems are typically integrated with other forms of public transport, like buses and taxis, to create a seamless travel experience. Urban rail networks are essential for promoting sustainable urban development and improving accessibility in densely populated areas.
