Among those are Los Angeles agencies like Metro and Metrolink; they are just two of the hundreds of agencies whose data goes to the GTFS, which keeps tabs on details like train and bus lines, schedules and stop frequency.

Each stop is a tiny white dot on a broad black expanse; in L.A.'s Metro, though, you can soon see the transit landscape of the city emerge above the blue base of the Pacific, with Downtown a bright hub. A little less blingy is Metrolink, with its commuter trains crisscrossing the county.
