Description

Don't leave for the T until you have to - and enjoy the feeling of walking down to the platform right as the train is arriving!

The application also includes a list of when the first and last trains leave, so you don't get stuck in Boston without a ride.

FAQ
Where's the Green Line?
Unfortunately, Green Line trains do not have realtime tracking equipment onboard. This is why you do not hear announcements in Green Line stations about trains approaching and arriving like you do on the other lines, and is also why Realtime T is unable to predict when they will arrive. The MBTA has stated that it is working on adding the technology, and though it may take several years for them to do so, we will support it when it becomes available.

How do the predictions work?
Sensors placed along the tracks can detect passing trains, providing Realtime T with train location data via the Internet. It's the same data used to activate the "next train is approaching" announcements you hear at most stations. Arrival predictions are made by using the train's current location, known transit times between stations, and the expected duration of each stop based on past trips.
