List of Massachusetts Bay Transportation Authority yards


The Massachusetts Bay Transportation Authority uses a number of yards and facilities for maintenance and storage of its road and rail fleets.

Active yards

Bus and trolleybus

Many of these facilities are former streetcar carhouses that were gradually converted to trackless trolley and bus use, although some like Southampton are of recent construction.

Commuter rail

All MBTA Commuter Rail lines have a dedicated layover near the end of the line for 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.
