Atlas

22 rail networks, 2,670 stations and 38,273 scheduled trips. Every map here was generated by the same code from the agency’s own published schedule, with no per-city drawing and no manual correction.

Each network links to a running map: a real service day, at whatever speed you want to watch it. They are ordered by size, so New York comes first.

On the imperfections

Where a network above lists caveats, they are real, and I have left them visible rather than quietly dropping the affected trains. Most come from the same two places: an agency numbering its platforms in a way the schematiser merges differently than the timetable expects, or a network dense enough that some station names have nowhere to sit without overlapping another.

Miami is the weakest result here, and the reason is interesting — Metrorail and Metromover are almost separate systems sharing one feed. Washington DC is missing entirely, because WMATA publishes its GTFS only behind an API key.
