County Dublin interactive metro and subway map. Underground and rapid transit lines, full network coverage — filterable by construction status.
County Dublin every underground, elevated and at-grade rapid transit line drawn from data mapped by OpenStreetMap contributors. Metro systems — also called subway, underground, U-Bahn, MRT or rapid transit depending on the country — are fully grade-separated electric railways built for high-frequency urban mass movement. The map covers systems at every scale: from the 400+ station networks of Tokyo, Moscow and Beijing to single-line systems in mid-sized cities. All sections are shown — deep-level tunnels, cut-and-cover subways, surface runs and elevated viaducts — giving a complete picture of where the metro network goes underground and where it emerges.
