List of urban rail systems by length

This is a list of the longest underground/surface/elevated subways, metros and rapid transit modules of the world. Metropolitan railways are urban, electric transport systems with high capacity and a high frequency of service. Metros are totally independent from other traffic, road or pedestrians. They are consequently designed in tunnel, viaducts or on surface level but with physical separation.
