Winter Weather – What to Expect

During severe weather, the MBTA may operate with reduced severe winter weather service plans

The MBTA works year-round to prepare for harsh winter weather. Our crews work to weatherize equipment and facilities to keep you moving when winter weather occurs. During inclement weather, check here regularly for information on service impacts and delays.

Online winter information can be found at the MBTA's winter resource hub: Use this site as your source for information on the MBTA’s service during the winter months. 

During routine winter weather, including severe cold and moderate snow, the MBTA will operate regular schedules. In some instances, buses may operate on Snow Routes or have minor delays. Remember to check T-Alerts regularly for updates.

During severe winter weather, the MBTA may also operate reduced service. Check back regularly to determine whether severe weather service plans are in place.

The Red, Blue, Orange, Silver, and Green Lines may operate at reduced levels during severe winter weather, resulting in less frequent service.

The Mattapan Hi-Speed Line may also be replaced by bus shuttles during severe weather.
