Porter station

Early history There has been a railroad station at Porter Square since the Fitchburg Railroad began operations in the early 1840s. The first station, built in 1843–1845, was called '''Porter's Station. A new station building was constructed in 1854. Later stations at the site were known as North Cambridge, then later simply as Cambridge'''. In 1869, the original station was moved to the North Avenue (now Massachusetts Avenue) bridge over the tracks. In 1937–38, the Boston and Maine Railroad built a two-story brick depot by the bridge, with the ticket office at street level and the waiting room and platforms below. The new station opened on May 2, 1938; the old station was demolished to make room for a parking lot for the adjacent Sears, Roebuck and Company store. As passenger traffic declined, the B&M sold and leased disused station buildings; the Cambridge station was converted to office use by 1968. MBTA era By the time the newly formed Massachusetts Bay Transportation Authority (MBTA) began subsidizing northside commuter rail operations in the late 1960s, both the Lexington Branch and the Central Mass Branch had been reduced to single rush hour round trips on poorly maintained track. The South Sudbury run on the Central Mass was terminated on November 26, 1971. On September 30, 1980, construction worker Paul Leone was killed when a retaining wall collapsed. A new glass and concrete headhouse was built around 1982, and the complete new transfer station opened on December 8, 1984, along with . A second entrance on the west side of Massachusetts Avenue was added in the late 1980s. Because of its Red Line connection, Porter Square can serve as a temporary inbound terminus for the Fitchburg Line service when commuter rail service is disrupted between Porter and Boston's North Station. It served this role during the 2004 Democratic National Convention, when North Station was closed for a week for security purposes, and during Green Line Extension construction in 2015 and 2019–20. Additional weekday short turn service was operated between Porter and North Station from July 15–26, 2024, providing half-hour headways between those points while the Red Line was closed for maintenance work. The staircase from Somerville Avenue was removed in 2020 during retaining wall reconstruction; a new staircase may be added later. An extension of the Union Square Branch of the Green Line Extension from to Porter has been proposed by local officials. ==Station layout==

Porter station has a glass-covered headhouse located on the east side of Massachusetts Avenue just south of Somerville Avenue. The station has four below-ground levels.. The Fitchburg Line runs approximately east-west in an open cut, with a single island platform between the two tracks. Most of the platform is low, with a raised mini-high platform at the west end under Massachusetts Avenue. Direct stair entrances to the platform are located on both sides of Massachusetts Avenue. A mezzanine, partially under Somerville Avenue east of White Street, is one level deeper. It contains fare machines, faregates for the Red Line, a convenience store, and – unusually for the MBTA system – public restrooms. Passengers reach Red Line platforms via a series of escalators, stairs totalling 199 steps, or a set of elevators. The longest single span of the escalators is , the longest in the MBTA system. Accessibility Porter is fully accessible; elevators lead from street level to the mezzanine with its accessible bathrooms, to the commuter rail platform, and to both Red Line platform levels. Although most of the commuter platform is low, there is a "mini-high platform" – a one-car-length high section – that allows level boarding. The station was originally built with three elevators: from Elm Street to the fare lobby, from the lobby to both Red Line platforms, and from the lobby to the commuter rail platform. The three existing elevators were overhauled, and two redundant elevators were added, in a $12 million project. An elevator from Massachusetts Avenue to the lobby opened later that year, followed by an overhaul of the existing street elevator; the redundant Red Line platform elevator was completed in 2013. ==Arts on the Line==

As a part of the Red Line Northwest Extension, Porter was included as one of the stations involved in the Arts on the Line program, devised to bring art into the MBTA's subway stations in the late 1970s and early 1980s. It was the first program of its kind in the United States and became the model for similar drives for art across the country. Six works, five of which remain, were placed at Porter: • Gift of the Wind by Susumu Shingu, a tall kinetic sculpture with three large red "wings" that rotate the structure in response to the wind • Ondas by Carlos Dorrien, a tall piece of undulating granite affixed to the station wall both inside the station and outside • Glove Cycle by Mags Harries, a large number of bronze gloves of varying types and sizes scattered inside the station, including alongside one of the escalators • Untitled by William Reimann, six granite bollards with various ethnic designs carved into them • Porter Square Megaliths by David Phillips, four boulders with large "slices" removed and replaced with bronze casts of the missing pieces • The Lights at the End of the Tunnel by William Wainwright, a large reflective mobile in the station's mezzanine. It was removed and put into storage in 1993 after a lead weight fell off. ==References==
