About Metroteca
What Metroteca is, where the diagrams and station coordinates come from, what counts as a metro and a city, how often the data is refreshed.
What it is
Metroteca is an atlas of the world's metro systems: 225 cities in 66 countries, 17,590 stations, 935 lines and 49,092 entrances. Every city has a page with its official diagram, the network drawn over real geography, every line with its colour and termini, key figures and rankings. On top of that: any two cities compared at the same scale, a gallery of all networks at one scale, rankings and a daily guess-the-metro game.
It is a reference, not a transit operator: no timetables, fares or journey planning.
Sources
- OpenStreetMap — station and entrance coordinates, line geometry, official colours and station order. ODbL; the derived database is open under the same licence, files on the licences page.
- Wikipedia, «List of metro systems» — opening year, official station count, length and ridership. CC BY-SA.
- Wikimedia Commons — official diagrams, each with its own author and licence shown beneath it.
- Wikidata — city names in other languages and links between sources. CC0.
OpenStreetMap and Wikipedia figures rarely match exactly: OSM counts stations as mapped objects, Wikipedia follows the operator's official statistics. Pages show both and label the source.
What counts as a metro and a city
The list of systems follows Wikipedia's "List of metro systems": fully grade-separated urban rail. German Stadtbahn, most light metro and trams are not included yet. A page is a city as a traveller understands it — the agglomeration: Tokyo includes Tokyo Metro, Toei and the Saitama lines; San Francisco includes BART and Muni.
Updates
Data is rebuilt from the sources roughly once a quarter; the data date is printed at the bottom of every city page (currently 2026-09-13). Outdated diagrams can be reported via the link on the city page or by email to hello@metroteca.com.
