Greenline displays the real-time arrival predictions and locations for all MBTA Green Line trains.

Greenline has a sleek and intuitive design. When you first open the app, it will find the nearest station, tell you how many minutes until the next train arrives, and show you where the train is currently located.

While you're waiting for your train, you can play with the interactive map and watch as Green Line trains move across Boston.

Meeting a friend? Let your friends know where you are by sharing you're train so they can track you in the app.

Greenline is powered by real-time vehicle prediction and location data provided by the MBTA.
