Back Bay station (also displayed as Back Bay · South End) is an intermodal transit hub situated in Boston, Massachusetts. Positioned just south of Copley Square within Boston's Back Bay and South End districts, it accommodates MBTA Commuter Rail, MBTA subway lines, and acts as a secondary Amtrak intercity rail terminal for the city. The existing facility, designed by Kallmann McKinnell & Wood, was inaugurated in 1987, replacing the 1928 Back Bay station originally built by the New Haven Railroad as well as the former New York Central's Huntington Avenue and Trinity Place stations that were demolished in 1964.
While South Station remains Boston's main railway hub, Back Bay experiences substantial passenger volume due to its prime proximity to the Prudential Center and its connection to essential Northeast Corridor routes. Every Amtrak Acela Express and Northeast Regional service that stops at South Station also calls at Back Bay, including the Boston segment of the Lake Shore Limited. The station is served by four MBTA Commuter Rail lines: the Providence/Stoughton Line, Franklin/Foxboro Line, Needham Line, and Framingham/Worcester Line. Additionally, it connects with the Orange Line subway and multiple local MBTA bus routes. It ranks as the third most frequented MBTA Commuter Rail station after North and South Stations and holds the position of sixth busiest among MBTA subway stations.
Station layout
Back Bay station comprises five tracks dedicated to Amtrak and commuter rail operations. Tracks 2, 1, and 3 (arranged from south to north) accommodate Amtrak’s Acela Express and Northeast Regional services alongside MBTA’s Providence/Stoughton Line, Franklin/Foxboro Line, and Needham Line. Tracks 5 and 7 serve the Framingham/Worcester Line as well as Amtrak’s Lake Shore Limited via a separate island platform. Tracks 1 and 2 serve as the principal mainline tracks; Boston’s track numbering system assigns odd numbers (3, 5, 7) to the side adjacent to Track 1 and even numbers to that beside Track 2. The Orange Line’s tracks and platform are situated between these two groups of mainline tracks.
The station offers full accessibility, featuring extensive high-level platforms along the Northeast Corridor tracks and a mini-high platform for the Worcester Line. Elevators provide access from all platforms to the street-level concourse.
The primary station building is located between Dartmouth Street and Clarendon Street, with additional exits onto Dartmouth Street, Clarendon Street, and Columbus Avenue. The Dartmouth Street Underpass connects the station to the adjacent Copley Place shopping center; this passage was temporarily closed for renovations during Copley Place’s construction from March 2016 through June 2017.
Earlier stations
The Boston and Worcester Railroad commenced operations from downtown Boston to Newton in 1834, eventually extending service to Worcester in subsequent years. That same year, the Boston and Providence Railroad began running trains from Park Square to East Providence. These rail lines crossed over causeways in what was then a mill pond area known as Back Bay. Around January 1, 1879, the successor company—the Boston and Albany Railroad—opened Columbus Avenue station to support new developments on reclaimed land in the bay. This modest structure made of corrugated iron was positioned just east of the Columbus Avenue bridge. In 1897, a collaboration between the New Haven Railroad, New York and New England Railroad, and Boston and Albany resulted in the formation of the Boston Terminal Company with the goal of uniting their terminals into a single new union station.
Simultaneous with the construction of South Station in 1899, the New Haven Railroad established its initial Back Bay Station east of Dartmouth Street to rival B&A’s Columbus Avenue stop. This Back Bay facility opened on September 19, 1899, coinciding with Providence Division trains starting service at South Station. The following year saw B&A replace Columbus Avenue with two separate stations: westbound-only Trinity Place and eastbound-only Huntington Avenue.
Modern station
The present-day Back Bay Station commenced operations on May 4, 1987, as a component of the Orange Line's Southwest Corridor initiative and was officially inaugurated by Governor Michael Dukakis. This facility succeeded the former station originally constructed in 1899 and reconstructed in 1929 by the ex-New York, New Haven and Hartford Railroad. Some elements of the old station remain visible at the eastern section of the current complex, including a carved stone embedded within the brick wall along Columbus Avenue. Upon reopening, the station also adopted South End as a secondary designation, a change authorized in 1985 amid a series of station renamings.
The 1987 redevelopment introduced a waiting area that features a 9-foot bronze statue commemorating civil rights and labor advocate A. Philip Randolph. This installation is complemented by displays containing historical photographs and interview excerpts that emphasize his role in organizing the Brotherhood of Sleeping Car Porters and his impact on the Civil Rights Movement.
In 1990, an accident occurred near Back Bay when a northbound commuter train on the Providence/Stoughton Line collided with a northbound Night Owl train, resulting in injuries to 453 individuals but no fatalities.
On September 22, 2006, the MBTA began offering free inbound rides from Back Bay to South Station to improve connectivity from hotels near Back Bay to the Boston Convention and Exhibition Center and Logan International Airport via the Silver Line. Until August 13, 2012, a customer service booth for special pass holders operated at Back Bay before relocating to the Downtown Crossing CharlieCard Store. The Orange Line platform underwent maintenance closure from August 19 to September 18, 2022; however, services by Amtrak and MBTA Commuter Rail continued without interruption.
Air quality
Back Bay station has faced persistent challenges with substandard air quality, largely due to trapped diesel exhaust within much of its enclosed commuter rail infrastructure. Passengers with respiratory conditions have been advised to avoid using this station. A petition submitted in 2000 brought renewed attention to these ongoing concerns. Subsequent studies conducted in 2006 and 2008 detected air quality significantly below acceptable levels, identifying elevated concentrations of carbon monoxide, formaldehyde, particulates, and oxides of nitrogen. Although some operational changes were implemented, the MBTA reported in 2008 that funding was inadequate to carry out comprehensive ventilation improvements.
In 2010, the MBTA obtained $3 million in federal stimulus funding aimed at enhancing lobby ventilation systems, targeting project completion by 2012. Nevertheless, air quality issues persisted, prompting Amtrak to withdraw its customer service representatives in 2014, rendering Back Bay an unstaffed station. Amtrak staff briefly returned in 2015 but were removed again in October 2016.
Despite lacking on-site staff, Back Bay continues to rank among the busiest Amtrak stations—placing fourth within New England and sixteenth nationwide as of 2018.
A $10 million ventilation enhancement project was put out for bid in 2016, jointly financed by MassDOT and Boston Properties. This initiative focuses on improving airflow at platform level and installing air curtains designed to prevent exhaust infiltration into the concourse area. By 2019, final design submissions were anticipated for delivery in 2020, with construction projected to extend through at least 2022. , the MBTA intends to solicit bids for a $38 million construction contract between April and June 2025.
Privatization and Renovation Efforts
In 2010, Boston Properties (later rebranded as BXP) purchased the neighboring parking garage. Four years later, the company reached an agreement with the state to develop air rights above both the station and garage. In return, BXP assumed responsibility for station management and committed to a $25 million refurbishment. Comparable private operation arrangements exist at North and South Stations, though those do not include real estate developments. By late 2014, a formal contract was established, increasing the renovation budget to $32 million. Due to retail rental income falling short of projections, the MBTA began providing financial support to Boston Properties in August 2015 and agreed to cover further maintenance costs.
Boston Properties commenced the permitting process with the Boston Redevelopment Authority (BRA) in December 2015. Released in March 2016, the proposed plans featured restoration of original architectural elements, repositioning of Orange Line entrances, enlargement of waiting areas, bathroom upgrades, enhanced ventilation systems, and additional retail spaces around the concourse. Station renovations were anticipated to begin in 2017, contingent on BRA approval. By 2019, construction was rescheduled for 2021. However, in 2024, BXP announced a suspension of the tower development project. Preliminary renovation activities are slated for June through November 2025, with main construction expected from November 2025 until April 2027.
Upgrades including wayfinding signage, lighting enhancements, and other improvements to the Orange Line station were completed by May 2021. On September 26, 2021, an escalator malfunction at the station resulted in injuries to nine individuals. The MBTA has plans to install fare gates on commuter rail and Amtrak platforms later in 2025.
