Close

Three small platforms on asphalt crossings serve as flag stops for MBTA employees only. One platform serves the Fitchburg Line, another the Lowell Line, and a third the Haverhill Line and Newburyport/Rockport Line (which split a mile north of the CRMF).

It was considered as a possible location for a light rail maintenance facility for the under-construction Green Line Extension.^[2] The Green Line facility was ultimately built on an industrial site just west of the Commuter Rail facility.^[3]
