Page "Orange Line (MBTA)" Paragraph 15

Between April 30 and May 3, 1987, the Washington Street Elevated south of the Chinatown station was closed to allow the Orange Line to be tied into the new Southwest Corridor.

On May 4, 1987, the Orange Line was rerouted out of the southern end of the Washington Street Tunnel and onto the new Southwest Corridor.

Instead of rising into elevated tracks, it now veered west at the Massachusetts Turnpike and followed the Pike and the old Boston and Albany Railroad right-of-way to the existing MBTA Commuter Rail stop at Back Bay.

It then continued along new tracks, partially covered and partially open but depressed, to Forest Hills.

This right-of-way is also shared by Amtrak as part of the national Northeast Corridor intercity passenger rail service.
