What are T-Alerts?

Sign up for T-Alerts to receive notifications about delays and planned disruptions for the routes and services you use the most. T-Alerts are delivered via email or text message.

When will I receive alerts?

During the signup process, you can select the time of day you prefer to receive alerts. We recommend selecting the times around your commute.

For each route you receive alerts for, you can select some or all of the following times:

DescriptionStart TimeEnd TimeDays
DescriptionEarly AMStart Time2:30 AMEnd Time6:59 AMDaysEvery day
DescriptionAM PeakStart Time7:00 AMEnd Time8:59 AMDaysMonday through Friday
DescriptionMiddayStart Time9:00 AMEnd Time3:59 PMDaysMonday through Friday
DescriptionPM PeakStart Time4:00 PMEnd Time6:29 PMDaysMonday through Friday
DescriptionEveningStart Time6:30 PMEnd Time2:29 AMDaysMonday through Friday
DescriptionWeekendStart Time7:00 AMEnd Time2:29 AMDaysSaturday and Sunday

What information is included in alerts?

Alerts include the severity of delays, the lines that are impacted, and the reason for the delay.

If only 1 direction of service is impacted, the alert will specify which direction.

For example, “Red Line is experiencing minor northbound delays due to a disabled train.”

If both directions of service are impacted, no directional information will be provided. For example, “Red Line is experiencing minor delays due to a disabled train.”

    Is it better to receive email or text alerts?

    Both alerts contain the same information, so it’s up to you. Text alerts are more convenient, but emails sometimes contain more details about the nature of the delay.

    Can I change my T-Alerts preferences and unsubscribe?

    Yes! If you want to adjust the time of day you receive alerts or which routes you'd like to receive alerts about, just sign into your account.

    You can easily unsubscribe in your account settings. If you receive text alerts, simply text the word “STOP” to 468311. 

    Who do I contact if I have a problem with T-Alerts?

    T-Alerts are provided through a company called GovDelivery. Please use their Subscriber Help Center to report any subscription issues. 

    If you have questions about service disruptions, please contact MBTA Customer Support.
