Google has been showing locations of train, bus or subway stops on its maps, but now those locations will link directly to more detailed information about a specific station, route, or schedule, according to the Google LatLong blog. An example shows data for the NYC subway at 59th St - Columbus Circle Station, New York.
Transit info is gathered from a city's transit agency, geographic data companies, or other sources. A city transit organization can submit their data to Google for inclusion via a text file feed.
