Gilman Square station
Gilman Square station is a light rail station on the Massachusetts Bay Transportation Authority Green Line located at Gilman Square in Somerville, Massachusetts. The accessible station has a single island platform serving the two tracks of the Medford Branch. It opened on December 12, 2022, as part of the Green Line Extension, which added two northern branches to the Green Line, and is served by the E branch.
The location was previously served by railroad stations. The Boston and Lowell Railroad opened a station at Winter Hill in 1863; it was rebuilt in 1886–1888. The station was served by the Boston and Maine Railroad, successor to the B&L, until 1937. Extensions to the Green Line were proposed throughout the 20th century, most with Winter Hill as one of the intermediate stations. A Gilman Square station at the Winter Hill site was officially chosen for the GLX in 2008. Cost increases triggered a wholesale reevaluation of the GLX project in 2015, and a scaled-down station design was released in 2016. A design and construction contract was issued in 2017. Construction of Gilman Square station began in early 2020 and was largely completed by late 2021.
Station design
Gilman Square station is located between School Street and Medford Street in the eponymous neighborhood in central Somerville, adjacent to Somerville City Hall and Somerville High School. The Lowell Line runs roughly northwest–southeast through the station area, with the two-track Medford Branch of the Green Line on the south side of the Lowell Line tracks. The station has a single island platform, long and wide, between the Green Line tracks. A canopy covers the full length of the platform.The platform is high for accessible boarding on current light rail vehicles, and can be raised to for future level boarding with Type 9 and Type 10 LRVs. It is also provisioned for future extension to length. The tracks and platform are located below street level.
The Somerville Community Path runs at street level along the south side of the rail lines. There are two entrances: from the School Street bridge at the west end of the platform, and from the Community Path at the east end. Both entrances have stairs and a single elevator for accessibility. A 100-space "Pedal and Park" bike cage and 40 bike racks are located along the Community Path next to the entrance. The Pearl Street Traction Power Substation is located northeast of the station along Medford Street.
History
Railroad station
The Boston and Lowell Railroad opened between its namesake cities in 1835; local stops were added after several years. Medford Street crossed over the railroad on a bridge by 1852, while a bridge was added in 1856 to extend School Street over the railroad. Winter Hill opened as a stop at Gilman Square in Somerville on January 1, 1863, with a station building added soon after. The original station building was a long wooden structure north of the tracks just west of Medford Street.In 1870, the Lexington Branch was routed over the B&L east of Somerville Junction, increasing service to Somerville Junction, Winter Hill, Milk Row, and East Cambridge stations. The Massachusetts Central Railroad began operations in 1881 with the Lexington Branch and B&L as its Boston entry. Gilman Square was named after Charles E. Gilman, Somerville's first town and city clerk. Before becoming town clerk, Gilman worked for the B&L and sold the first ticket between its two terminal destinations.
A foundation was laid in 1886 for a new stone station on the south side of the tracks. The Boston and Maine Railroad acquired the B&L in 1887. The new station opened in 1888; the old wooden station was split into two sections which were reused as houses, which are still standing near Magoun Square. The new station was made of red marble ashlar with rough marble trim; the waiting room featured a marble fireplace. On February 3, 1898, a Lexington Branch express collided with a Stoneham Branch local at the station, injuring about 40 passengers.
The inner suburban stations lost much of their ridership to streetcars, especially after the Lechmere Viaduct sped travel times to downtown beginning in 1912. The ticket office at Winter Hill was closed in 1926. On April 25, 1927, the Lexington Branch was reconnected to the Fitchburg Line; the 1870-built line west of Somerville Junction became the Fitchburg Cutoff used only by freight trains. Three stations on the cutoff plus Prospect Hill and East Cambridge stations east of Winter Hill were closed entirely. The railroad unsuccessfully attempted to sell the Winter Hill station building for reuse. The abandoned station building was demolished in July and August 1934, as it had become a target for vandalism. A small number of trains continued to stop until February 19, 1937. The stone base of the former station was used to house electric equipment until Green Line Extension construction began in 2018.
During the late 1960s and early 1970s, the newly formed MBTA reopened several inner-suburb commuter rail stations in response to community desire for service that was faster if less frequent than buses. In 1976, Winter Hill station was considered for reactivation, but ridership was expected to be negligible due to the nearby route,,, and 94 buses.
Green Line Extension
Previous plans
The Boston Elevated Railway opened Lechmere station in 1922 as a terminal for streetcar service in the Tremont Street subway. That year, with the downtown subway network and several radial lines in service, the BERy indicated plans to build three additional radial subways: one paralleling the Midland Branch through Dorchester, a second branching from the Boylston Street subway to run under Huntington Avenue, and a third extending from Lechmere Square northwest through Somerville. The Report on Improved Transportation Facilities, published by the Boston Division of Metropolitan Planning in 1926, proposed extension from Lechmere to North Cambridge and beyond via the Southern Division and the 1870-built cutoff. Winter Hill was to be the site of an intermediate station in this and subsequent plans.In 1945, a preliminary report from the state Coolidge Commission recommended nine suburban rapid transit extensions – most similar to the 1926 plan – along existing railroad lines. These included an extension from Lechmere to Woburn over the Southern Division, again with Winter Hill as an intermediate stop. The 1962 North Terminal Area Study recommended that the elevated Lechmere–North Station segment be abandoned. The Main Line was to be relocated along the B&M Western Route; it would have a branch following the Southern Division to Arlington or Woburn.
The Massachusetts Bay Transportation Authority was formed in 1964 as an expansion of the Metropolitan Transit Authority to subsidize suburban commuter rail service, as well as to construct rapid transit extensions to replace some commuter rail lines. In 1965, as part of systemwide rebranding, the Tremont Street subway and its connecting lines became the Green Line. The 1966 Program for Mass Transportation, the MBTA's first long-range plan, listed a short extension from Lechmere to Washington Street as an immediate priority, with a second phase reaching to Mystic Valley Parkway or West Medford.
The 1972 final report of the Boston Transportation Planning Review listed a Green Line extension from Lechmere to as a lower priority, as did several subsequent planning documents. In 1980, the MBTA began a study of the "Green Line Northwest Corridor", with extension past Lechmere one of its three topic areas. Extensions to Tufts University or were considered.
Station planning
In 1991, the state agreed to build a set of transit projects as part of an agreement with the Conservation Law Foundation, which had threatened a lawsuit over auto emissions from the Central Artery/Tunnel Project. Among these projects was a "Green Line Extension To Ball Square/Tufts University", to be complete by the end of 2011. No progress was made until an updated agreement was signed in 2005. The Beyond Lechmere Northwest Corridor Study, a Major Investment Study/alternatives analysis, was published in 2005. The analysis studied a variety of light rail, bus rapid transit, and commuter rail extensions, all of which included a Gilman Square station at the former Winter Hill station site. The highest-rated alternatives all included an extension to with Gilman Square as one of the intermediate stations.The Massachusetts Executive Office of Transportation and Public Works submitted an Expanded Environmental Notification Form to the Massachusetts Executive Office of Environmental Affairs in October 2006. The EENF identified a Green Line extension with Medford and Union Square branches as the preferred alternative. That December, the Secretary of Environmental Affairs issued a certificate that required analysis of Lowell Line stations at and Gilman Square in the draft environmental impact report for the Green Line Extension. Plans shown in early 2008 called for a Green Line platform between School Street and Medford Street, with no commuter rail platform.
Planned station sites were announced in May 2008. Unlike the other four stations on the Medford Branch, only one site – between School Street and Medford Street – was considered for Gilman Square station. The DEIR, released in October 2009, did not recommend the construction of a commuter rail platform at Gilman Square or Tufts University. The width of a platform and a gauntlet track for freight would require additional right-of-way width, which would have substantial impacts on adjacent properties. Preliminary plans in the DEIR called for the main station entrance to be on Medford Street at Gilman Square near Pearl Street, with an additional entrance from the Community Path on the south side. An emergency exit would connect to the School Street bridge.
Updated plans shown in May 2011 removed the direct entrance from the Community Path, replacing it with a footbridge from the path to the entrance plaza, and added a kiss and ride loop next to the headhouse. Plans presented in February 2012 added a second level to the headhouse, with the footbridge replaced by a direct entrance from the Community Path. The bike cage was relocated to the southwest side of the tracks, and a traction power substation was added near School Street. A further update in June 2013, with design 60% complete, reduced the size of the Medford Street headhouse and enlarged the Community Path entrance. The substation was moved below ground level. Design was then paused while Phase 2/2A stations were prioritized, as they were scheduled to open sooner than the rest of the GLX. Design resumed in fall 2014 and reached 90% by June 2015.
By 2012, the portion of the Medford Branch from Gilman Square station to College Avenue was expected to be completed by June 2019. A Gilman Square commuter rail station to supplement the Green Line station was again listed as a possibility in 2012 as an interim air quality mitigation measure in response to delays in building the Green Line Extension. However, such a station would have been costly to build and could not have been completed by the 2015 deadline, and was thus not supported by MassDOT.
