In Rome, transit data covers the city's public metro lines, buses, and tram routes, as well as the local Trenitalia network which includes the Leonardo Express that connects Roma Termini station and Roma Fiumicino airport in Lazio.
Transit coverage across Estonia includes the capital Tallinn's bus, tram, trolleybus, and Elron train services, as well as local links to the country's national rail network reaching through Tartu, Pärnu, and Narva.
The public transport information can be accessed by tapping the Transit tab or button in Apple Maps on iPhone, iPad, Mac, or Apple Watch.
Apple started adding transit information to Apple Maps three years ago, starting with Baltimore, Berlin, Boston, Chicago, London, Los Angeles, Mexico City, New York, Philadelphia, San Francisco, Sydney, Toronto, and China. Apple has since expanded transit coverage to additional cities around the globe.
Apple is gradually catching up with Google Maps' public transportation navigation coverage, which already includes Rome and cities in Estonia. Apple also recently revealed that CarPlay will support Google Maps, Waze, and other third-party navigation apps with a paired iPhone running iOS 12.
