Winter Weather Information

Winter Weather – What to Expect

In the event of severe winter weather, various modes of travel are likely to be impacted and the MBTA may have to make service adjustments.

The MBTA works tirelessly to prepare for the harsh conditions of winter. Crews regularly weatherize equipment and facilities to keep our aging system functioning when winter weather strikes. Despite our hard work, MBTA services will be adversely affected when key mechanical components and other pieces of equipment are subjected to heavy snow, icy conditions, and/or frigid temperatures. Winter storms can also impact the workforce as MBTA employees combat difficult road conditions when they are reporting for duty. It’s for these reasons that delays of varying degrees will be unavoidable. Customers are strongly advised to plan for extra travel time and to check this webpage before starting their commutes.

During severe winter weather, MBTA trains may operate at reduced service levels and some buses may operate on Snow Routes. 

Service information can be found at the MBTA's winter resource hub: Please use this site as your source for information on MBTA service during the winter months and remember to check T-Alerts regularly for updates.


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

The Mattapan Trolley may also be replaced by bus shuttles during severe weather.

Commuter Rail

During severe weather, the Commuter Rail may experience severe delays and cancelations.


Some bus routes may operate at reduced levels during severe weather, resulting in less frequent service.
