OpenMBTA will show you today's remaining scheduled arrival times for MBTA buses, subway trains, commuter rail lines, and ferries. It also has a section that shows you the latest T Alerts, which are service delay announcements from the MBTA. The goal is to promote public transportation in order to help fight global warming and reduce our dependency on the oil imports that keep autocratic regimes in power. OpenMBTA is part of a green software movement that calls on developers to donate their time to making free and useful software that helps us save the environment and promote democracy.
