About T-Alerts

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:

  • Early AM: 2:30 AM-6:59 AM, every day
  • AM Peak: 7:00 AM-8:59 AM, M-F
  • Midday: 9:00 AM-3:59 PM, M-F
  • PM Peak: 4:00 PM-6:29 PM, M-F
  • Evening: 6:30 PM-2:29 AM, M-F
  • Weekend: 7:00 AM -2:29 AM, Saturday 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.”

What are “minor,” “moderate,” and “severe” delays?

All delays are classified in 1 of the following ways. Please note that delays may be worse during rush hour.

Minor delays

  • You may wait a few minutes longer than normal for a train or bus.
  • Trains may wait longer at or before stations because of increased traffic.
  • Most minor delays are resolved quickly, and the impacts to your trip will be because we are adjusting service to return to normal.

Moderate delays

  • You will likely wait longer than normal for a train or bus, and vehicles and stops may be crowded.
  • Trains may wait longer at or before stations because of increased traffic.
  • It will take longer to return to normal service after moderate delays, and the impacts of that may be felt throughout the route.

Severe delays

  • Severe delays indicate that a route is blocked, for example, by a disabled train or severe traffic on a bus route.
  • Vehicles may hold at or in between stations until the issue is resolved.
  • Vehicles and stops are likely to be crowded.
  • Once the issue is resolved, it may take an hour or more to return to normal service, and we recommend seeking an alternate route.

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.
