# 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

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.
