The Massachusetts Bay Transportation Authority uses a number of yards and facilities for maintenance and storage of its road and rail fleets.
Many of these facilities are former streetcar carhouses that were gradually converted to trackless trolley and bus use, although some like Southampton (built 2004) are of recent construction. Of the former streetcar carhouses, only Arborway and Watertown were Green Line yards during part of the MBTA era. Everett was an Orange Line yard until 1975.

All MBTA Commuter Rail lines except the Lowell Line have a dedicated layover near the end of the line|trainsets to be stored overnight. Some provide ground power and other facilities; others are simply several yard tracks off the mainline. The MBTA has one heavy maintenance facility on the northside, plus two light maintenance facilities on the southside. Equipment is transferred between the two sides via the Grand Junction Railroad.
