Warsaw planned and proposed metro lines. Future underground routes and rapid transit expansion projects before construction begins.
Warsaw metro and subway lines formally proposed or in active planning: future underground corridors announced, studied or included in urban transport master plans but not yet under construction. Shows where cities plan to extend rapid transit coverage — new orbital lines connecting suburbs without routing through the city centre, extensions to areas beyond the existing network and entirely new metro systems in cities currently without subway.
Warsaw has 199 proposed railway segments including 60 railway, 82 tram and 57 metro.
