Spain planned and proposed railway lines. Future rail corridors, new route proposals and long-term network expansion projects before construction begins.
Spain railway lines formally proposed or in planning stages: routes announced, studied or included in national and regional transport plans but not yet under construction. Ranges from rail projects with confirmed funding to long-term corridors still in feasibility study. Shows the intended direction of future network growth — which cities are targeted for new rail connections, where high-speed rail networks have planned extensions and which corridors are being considered for entirely new alignments.
Spain has 717 proposed railway segments including 581 railway, 53 tram, 34 metro, 18 light rail and 31 narrow gauge.
