This listing includes stations that have closed during the MBTA era (since 1964) without replacement by another rapid transit station. Most former stops on Green Line A branch and the outer section of the Green Line E branch, which were merely marked stopping locations rather than platforms, are not listed. Closed with replacement. This listing includes stations that have closed during the MBTA era (since 1964), but were replaced with another rapid transit station. This includes stations rebuilt nearby on a different routing  of the same line (such as Forest Hills when the Washington Street Elevated was replaced with the Southwest Corridor), temporary stations (such as Harvard/Brattle), and stations replaced with Silver Line stops (such as Dover).
