Germany Proposed Metro Lines — Planned Subway Routes and Future Underground Expansions

Germany planned and proposed metro lines. Future underground routes and rapid transit expansion projects before construction begins.

Germany has 1,382 proposed railway segments including 740 railway, 369 tram, 81 metro, 185 light rail and 7 narrow gauge.
