[0002] The subway is a fast, high-capacity, electrically-driven rail transit system built in cities. Trains run on fully enclosed lines. Lines in the central urban area are basically located in underground tunnels, and lines outside the central urban area are generally located on viaducts or on the ground. The subway is an exclusive, high-density, high-capacity urban rail transit system covering various underground and above-ground right-of-way systems in urban areas.
