📅 Subscribe
To get these events in your own calendar, copy this iCal URL and add it to your
calendar app:
https://tcal.digitalcora.net/alerts.ics
The process for doing this varies, but in the end you’re looking for a box you
can paste a URL into (not something that asks you to upload a file). Look for
words like “feed”, “sync”, or “subscribe”. If stuck, try a web search for your
calendar app name plus “ical feed” .
Developer options
To easily inspect the raw feed in your browser, replace .ics
with

in the URL.
⚠ Limitations
The calendar only shows disruptions on rapid transit lines (Blue, Green,
Orange, Red). To get alerts about Commuter Rail, bus, or ferry disruptions,
try T-Alerts .
The calendar does not show all disruptions on rapid transit. The goal is to
surface disruptions that can substantially impact a ride, and are planned in
advance (and thus useful to display on a calendar). Shuttle buses and station
closures are typical examples.
The calendar does not show the exact time(s) a disruption is scheduled to
start and end; all disruptions are shown as “all-day” events. This creates a
more readable calendar view (and avoids cluttering your personal calendar, if
you subscribe to the feed). Check event descriptions for timing details.
The calendar does not show past disruptions. This is a limitation of the MBTA
alerts API, and working around it would not be worth the added complexity.
💬 Feedback
Issues and feature ideas are tracked on GitHub . Anyone (with a GitHub
account) can report bugs or suggest improvements there!
Before reporting an issue, check whether it is also present in the
alerts on mbta.com . If so, please report it to the MBTA
instead of this project.
