Île-de-France Proposed Metro Lines — Planned Subway Routes and Future Underground Expansions

Île-de-France planned and proposed metro lines. Future underground routes and rapid transit expansion projects before construction begins.

Île-de-France 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.

Île-de-France has 52 proposed railway segments including 5 railway, 15 tram, 26 metro and 6 light rail.
