Park Street station is a subway stop on the MBTA subway network situated in Boston, Massachusetts. It lies at the junction of Park Street and Tremont Street, positioned on the eastern boundary of Boston Common within Downtown Boston. As one of the oldest two stations on the "T" system—alongside Boylston—and a component of the country's earliest subway line, Park Street functions as a crucial interchange between the Green and Red lines. It is recognized as one of the MBTA's four principal "hub stations" and ranks fifth in terms of busyness, with an average weekday entry count of 16,571 during FY2019.
Tremont Street subway
The southern segment of the Tremont Street subway, stretching from the Public Garden incline through Boylston to Park Street, commenced operations on September 1, 1897. Shortly after, on October 1, a branch leading to the Pleasant Street Portal was inaugurated. The station comprised four tracks served by two island platforms interconnected by dual loops, facilitating streetcars arriving from southern and western directions to reverse course and return to surface routes.
By September 3, 1898, the tunnel extended further to reach Scollay Square, Adams Square, Haymarket Square, and the Canal Street Incline. Some streetcars utilized the outer tracks to traverse the tunnel directly, whereas others employed loops at Park Street to turn around.
The headhouses at Boylston and Park Street were constructed with rectangular stone designs by architect Edmund M. Wheelwright. These structures attracted criticism for their incongruity with the Common's landscape and were described as resembling "mausoleums." In response, subsequent stations on the East Boston Tunnel and Washington Street Tunnel adopted more understated headhouse designs.
In 1899, Park Street replaced human announcers with electric destination boards. Signal operators completed electrical circuits that illuminated numbers indicating berth assignments for arriving cars.
Main Line Elevated
On June 10, 1901, Main Line Elevated trains began operating through the Tremont Street subway. To accommodate these trains, platforms at Park Street were modified with raised wooden sections on the outer tracks leading to the Pleasant Street Portal; meanwhile, streetcars continued utilizing the inner tracks and loops. This arrangement persisted until elevated train service was transferred to a separate tunnel beneath Washington Street. The last elevated train passed through Park Street on November 28, 1908; by November 30, services shifted to the Washington Street Tunnel, and streetcar operations resumed across all tracks by December 4.
Cambridge subway
The Cambridge subway launched on March 23, 1912, connecting Harvard Square to Park Street Under. This lower-level station was designed with two tracks flanked by one side platform each and a central island platform arranged in a Spanish solution format to expedite passenger boarding. Staircases linked this new platform level to the original streetcar platforms above. Unlike most cut-and-cover underground stations characterized by low ceilings, Park Street Under featured an expansive double-vaulted ceiling.
This station was pioneering in adopting the "Under" suffix for transfer points rather than assigning entirely different names from existing stations—a strategy aimed at enhancing wayfinding within the complex system. Subsequent stations such as North Station West (1912), South Station Under (1916), and Scollay Under (1916) followed this naming convention. Construction of the Dorchester Tunnel commenced on May 3, 1912; it opened in phases extending service to Washington by April 4, 1915, then progressively reaching South Station Under (1916), Broadway (1917), and finally Andrew (1918).
Persistent overcrowding at Park Street—exacerbated by Main Line routing through it and increased transfers at Park Street Under due to narrow stairways connecting levels—prompted significant expansion prior to extending the Boylston Street subway and Cambridge subway lines. The Boston Transit Commission undertook substantial enlargement of the streetcar level: platforms were extended southward and straightened out; specifically, the southbound platform increased in size by half while the northbound grew by three-eighths. Additionally, the south headhouse serving southbound passengers was relocated to the far end of this expanded platform area. Construction started on August 7, 1914, and concluded on March 8, 1915.
1920s–1960s
In 1921, a loudspeaker system was installed to facilitate announcements. On December 15, 1923, the Park Street Information Booth, a well-known Boston landmark, opened its doors, replacing an earlier kiosk. A notable incident occurred on January 3, 1925, when an explosion caused by celluloid film carried by a passenger injured numerous individuals on a streetcar arriving at the station.
Although the 1914–15 renovation expanded platform space, narrow stairways continued to impede passenger movement. To address this, in August 1921, the single stairway connecting the lower center platform to the upper northbound platform was replaced by two separate stairways. The following year, in August 1922, stairways between the southbound platforms were widened. By December 1924, the stairway linking the upper southbound and lower northbound platforms was doubled in width to handle increased traffic from the East Boston Tunnel. Further widening of stairs between the upper northbound and lower southbound platforms was completed by May 1925. These modifications resulted in a reduction of space at the northern ends of streetcar platforms, shifting boarding zones toward the south.
In July 1922, the Boston Transit Commission proposed constructing a side platform alongside the outer northbound streetcar track, including an underground passage beneath Tremont Street leading to new entrances on Temple Place. Although opening the Winter Street Concourse to passengers was considered, it was ultimately rejected by the Department of Public Utilities, which preferred to use it for storage by nearby businesses. A more extensive plan introduced in 1927 envisioned side platforms on both sides of the streetcar level with an underground passage connecting all platforms and entrances. By 1933, stairway headhouses on the east side of Tremont Street were replaced with low walls.
To alleviate persistent overcrowding issues, the Boston Transit Department built a new northbound side platform beneath Tremont Street in 1936 with entrances at Temple Street. This project included a sub-passage linking streetcar platforms and connected the new platform directly to the Cambridge Tunnel fare lobby; however, it did not open access to the Winter Street Concourse. Funded by $407,000 from the Works Progress Administration (equivalent to $ in ), construction began on January 8, 1936, and the platform became operational on December 5.
The 1947 legislation establishing the Metropolitan Transit Authority (MTA) from the Boston Elevated Railway incorporated plans to expand the Tremont Street subway to four tracks between Park Street and Scollay Square. One proposal suggested merging Park Street and Boylston stations into a single Boston Common station with direct access from an underground parking garage. Although this garage opened in 1961, both stations remained separate entities. Additionally, in 1963, the south headhouse on the northbound side was removed.
MBTA era
In 1964, removal of the outer loop track made way for a crossover switch that allowed southbound streetcars to use either side of the southbound platform. Attempts to restore the outer loop track have been delayed due to expensive structural reinforcement requirements. A short stub "pit" track remains available for emergency purposes. Two years later, in 1966, the south headhouse was repurposed as an information booth dedicated to the Freedom Trail but functioned solely as an exit.
The MBTA introduced color-coded names for subway lines in 1967: transforming the streetcar system into the Green Line, renaming Cambridge–Dorchester as Red Line, and designating Main Line El as Orange Line. During the 1970s, street musicians were officially permitted to perform within stations under MBTA policy. Park Street station also served as a filming location for multiple productions such as See How She Runs (1978) and Spenser: For Hire (1985–88).
1970s modernization
During the 1970s, Park Street station underwent its first significant refurbishment in forty years. A federal grant covered two-thirds of a $14.3 million initiative aimed at modernizing downtown stations, with $4.2 million allocated specifically to Park Street. The MBTA considered creating pedestrian tunnels to connect Essex, Park Street, Downtown Crossing, and State stations.
In December 1976, a contract worth $3.6 million was awarded for the project. By 1977, the 1936 Temple Place entrance was closed and concession areas were removed. The renovation efforts encompassed installing new wall tiles and lighting, reconstructing stairways, upgrading faregate zones, and replacing the original copper headhouses with contemporary glass-and-steel designs. Elevators introduced in 1979 enhanced Red Line accessibility, although the reliability of surface-level elevators posed challenges.
The Winter Street Concourse, a pedestrian passageway linking Park Street and Downtown Crossing, opened in January 1979 after clearing previously restricted areas. This concourse enables passengers to transfer between the Green and Orange Lines without exiting fare control. Despite these improvements, some critics expressed dissatisfaction with the station’s appearance following the renovation.
Later changes
Between August 1981 and June 22, 1996, additional Red Line trains operated during peak hours between Quincy Center station and Park Street, reversing direction via crossovers located north of Park Street. From November 30, 1981, until June 1982, Park Street functioned as the northern terminus for certain five-car trains—the first trains longer than four cars—until platforms further north were lengthened.
In the mid-1980s, the MBTA allocated $80 million to extend platforms at seven Red Line and three Orange Line stations to accommodate six-car trains. A $22 million federal grant awarded in 1984 helped fund improvements at Central, Park Street, and Washington stations. Platform extensions at Park Street took place from 1985 to 1986, with six-car train service commencing on January 21, 1988. Temporary artworks displayed during this period included an interactive synthesizer created by Christopher Janney as part of the Arts on the Line initiative.
In March 1991, the MBTA solicited bids for further construction work; a contract valued at $6 million was granted in July of that year. Completed by 1993, this project introduced elevators to the Green Line sub-passage, enabling elevator access to all platforms—although Green Line trains themselves remained inaccessible. The northbound Green Line headhouse became accessible in June 1992; around that same time, a new south headhouse was constructed nearby but functioned as exit-only until automated fare collection was installed circa 2007.
Around the year 2000, portable lifts were installed on Green Line platforms to temporarily accommodate low-floor Type 8 streetcars. A $15 million project initiated in 2001 built raised low platforms at Park Street and , completed in stages by 2003 to maintain ongoing service.
New elevators connecting street level to the westbound Green Line unpaid lobby and from that platform to the Red Line island platform were opened on December 21, 2012. These installations were part of the 2006 settlement in Joanne Daniels-Finegold, et al. v. MBTA. Early in 2019, the MBTA requested bids for an $11.8 million renovation of Park Street station involving updated signage, improved lighting, and reopening the Temple Place exit that had been closed since 1976. Work commenced in April 2019 and was largely completed by December 2020 except for reopening that exit.
The elevator linking the Red Line lobby to its platform is scheduled for replacement as part of accessibility upgrades at Downtown Crossing. In April 2025, bidding began for a $95 million construction manager-at-risk contract covering this elevator along with similar improvements at and Downtown Crossing stations; construction is planned from April 2026 through January 2031.
Station layout
Park Street station is designed with two levels: the upper tier accommodates the Green Line, while the Red Line operates beneath it. The Green Line consists of four tracks numbered 1 through 4 from north to south. Tracks 1 and 2 share an island platform serving westbound trains; Tracks 3 and 4 are served by another island platform for eastbound trains, alongside a side platform adjacent to Track 4. Eastbound through trains exclusively use Track 4, whereas Track 3 is reserved for trains that terminate at Park Street and then reverse direction back to Track 2. Both island platforms have headhouses and fare control areas located at their northeast ends, with an additional southwest headhouse present on the westbound platform. A connecting sub-passage links all three Green Line platforms, while a passageway from the eastbound side platform leads to a fare lobby situated beneath Winter Street, which provides stair access to the street level and connects to the Winter Street Concourse, facilitating transfers to Downtown Crossing.
The Red Line operates on two tracks: Track 5 for southbound trains and Track 6 for northbound services. Boarding and alighting occur on both island and side platforms. Each Red Line platform is connected via stairways to the Green Line island platform and fare lobby. Exit-only escalators are installed at the southern ends of the side platforms, leading directly to the surface. Above the Red Line platforms, on the Green Line level, there is a secondary control room serving as a backup for the subway system.
While Park Street is not a primary bus transfer point, MBTA bus route services stop nearby at Tremont Street and Temple Place. Additionally, Silver Line routes serve stops on Temple Place between Park Street and Downtown Crossing, where MBTA transit maps indicate available connections.
Accessibility
The station ensures full accessibility for all train passengers. Elevators provide vertical access from street level to the westbound Green Line platform and fare lobby. The central Red Line platform is accessible via elevators linking it with both the westbound Green Line platform and fare lobby; however, accessibility does not extend to the Red Line’s side platforms. Elevators also connect the westbound Green Line platform and eastbound side platform to the sub-passage corridor. Since no elevators connect the Red Line at Park Street directly with the southbound Orange Line at Downtown Crossing, passengers requiring accessible transfers must use the Winter Street Concourse in conjunction with Park Street’s elevator facilities.
Public art
Prominent public artworks enrich Park Street station’s environment. Celebration of the Underground, created by Lilli Ann K. Rosenberg, is a large-scale mosaic adorning the wall along the outbound Green Line tracks. This piece honors the Tremont Street subway—including Park Street station itself—as a designated National Historic Landmark. Originally installed in 1978, it underwent restoration and enhanced lighting improvements in 2020.
Another significant installation is Benedictions by Ralph Helmick, featuring two monumental bronze hands positioned above both inbound and outbound Red Line tracks on the station’s lower level. Each hand represents a traditional benediction gesture.
