Warren Street station (MBTA)
Warren Street station serves as a light rail stop on the MBTA Green Line, specifically the B branch. It is situated along Commonwealth Avenue at the intersection with Warren Street in the Allston neighborhood of Boston, Massachusetts. The station features two side platforms positioned on either side of the Warren Street level crossing, accommodating two tracks, but it lacks accessible facilities.
History
The streetcar route commenced operations on May 26, 1900, when the segment connecting Packards Corner to Chestnut Hill Avenue was inaugurated, creating a link between pre-existing tracks to the east and west. Unlike earlier portions that ran within a central median, this stretch was constructed in a reserved area located between the southbound traffic lane and an adjacent frontage road. Between Warren Street and Wallingford Road, this reserved space extended wider than the tracks themselves. In 1960, the addition of new southbound lanes resulted in southbound vehicles crossing the B branch tracks at Warren Street.
Prior to 1983, only a curb separated the inbound platform from vehicular traffic. During a track replacement project from July through September 1983, the station underwent reconstruction that included installing a low protective wall on the inbound platform and adding a small shelter for passengers.
Track maintenance during 2018–19 led to mandated accessibility improvements at multiple stops; however, Warren Street was not included at that time. The planning phase for upgrades to five stops along the B Branch started in 2021. By 2024, Warren Street and other remaining non-accessible stations on the B Branch were incorporated into this initiative. Because of their close proximity and a steep incline just south of Warren Street, plans call for combining Warren Street and the nearby stop into one fully accessible station.
As of February 2025, the MBTA intends to issue a $74 million design-build contract for bidding by May 2025, with construction anticipated to begin in fall 2025 and conclude by mid-2027.
