Bus
Several of the current facilities were initially constructed as streetcar carhouses and later adapted for trackless trolley and bus operations.

Commuter rail
With the exception of the Lowell Line, all MBTA Commuter Rail routes feature designated layover areas located close to their endpoints. Most of these sites offer ground power and amenities for storing trainsets overnight, while some are comprised of yard tracks situated off the main tracks. The MBTA manages a single heavy maintenance center on the northern side and two light maintenance facilities on the southern side. Transfers of equipment between the north and south sides are conducted via the Grand Junction Railroad.
