Google Maps Now Empowered with Live Public Transit Information
Google says that it now offers information for 100 million miles of daily public transit in 800 cities spread across 25 countries; that data includes everything from fares to departure times to estimated travel times.
There are more specific additions, too, including live departure times for seven lines of the subway in New York City and buses and trams in Salt Lake City as well as live service alerts for the Metrorail in Washington, D.C.

The Google Maps update is available for Android and iOS devices.
