'''Harvard station''' is a [[rapid transit]] and bus transfer station in [[Cambridge, Massachusetts]]. Located at [[Harvard Square]], it serves the [[MBTA]]'s [[Red Line (MBTA)|Red Line]] subway system as well as [[MBTA bus]]es. Harvard averaged 18,528 entries each weekday in FY2019, making it the third-busiest MBTA station after {{bts|Downtown Crossing}} and {{bts|South Station|Red}}.<ref name=fy2019counts />

Harvard station is located directly beneath Harvard Square, a transportation, business, and cultural focal point in Cambridge. The Red Line rail platforms lie underneath [[Massachusetts Avenue (Boston)|Massachusetts Avenue]] just north of the center of the square. Many connecting surface transit routes are served by the '''Harvard bus tunnel''', which runs on the west side of the station. The primary station entrance leads to a central atrium fare lobby under Harvard Square; there is also a secondary fare lobby for the Red Line toward the north end of the station, with entrances at Church Street and opposite it, near Harvard's [[Johnston Gate]]; and an unpaid entrance to the bus tunnel at Brattle Square.

==Station layout==
[[File:Harvard station platforms from above August 2024.jpg|thumb|left|Red Line platforms viewed from the secondary fare mezzanine: the outbound platform is to the left, with the inbound platform visible below to the right.]]
Harvard station has a complex structure located largely under triangular Harvard Square, from which Massachusetts Avenue runs to the north and east and Brattle Street to the southwest, and under the surrounding streets. The main lobby is located under the square itself, and approximately matches its triangular shape. The glass-and-steel main headhouse is located in a sunken concrete plaza at the south end of the square.<ref name=dedicates /> The plaza, locally known as "the Pit", plays host to homeless people, street artists, skateboarders, and activists.<ref>{{cite news |url=https://www.thecrimson.com/article/2005/4/25/four-convicted-in-01-pit-murder/ |title=Four Convicted in '01 Pit Murder |newspaper=Harvard Crimson |date=April 25, 2005 |first=Reed B. |last=Rayman}}</ref><ref>{{cite news |url=http://www.bu.edu/articles/2009/getting-to-know-your-neighborhood-harvard-square/ |title=Getting to Know Your Neighborhood: Harvard Square |newspaper=BU Today |date=September 11, 2009}}</ref> Passengers descend eastward from the headhouse on a bank of stairs and elevators, then turn and descend northwest on a second escalator bank into the lobby. An elevator is located adjacent to the headhouse; the station is fully [[accessibility|accessible]].<ref name=dedicates />

The Red Line platforms are located on two stacked levels, north of the square under Massachusetts Avenue.<ref name=rollsign1983 /> The outbound (northbound) track is above and slightly east of the inbound track; both have [[side platform]]s on their west sides.<ref name="nyc"/>  These [[split platform]]s run from near the south end of Harvard University's [[Straus Hall]] to the south part of [[Flagstaff Park]] near Garden Street.<ref name=rollsign1983 /> A pair of ramps lead from the main lobby{{nbsp}}— which has faregates on its north side{{nbsp}}— to the platforms. A secondary fare lobby is located above the middle of both platforms, with small brick headhouses on both sides of Massachusetts Avenue at Church Street near [[Johnston Gate]].<ref name=rollsign1983>{{cite magazine |title=Harvard Station on Red Line Opened |first=Charles |last=Bahne |date=November–December 1983 |magazine=Rollsign |pages=3–8 |publisher=Boston Street Railway Association |volume=20 |issue=11/12}}</ref>

===Bus tunnel===
[[File:MBTA 75 bus at Harvard Station.jpg|thumb|left|A route 75 bus on the upper level of the bus tunnel]]
Immediately west of the subway platforms is the {{convert|1380|feet|adj=on}}-long Harvard bus tunnel, used by MBTA buses and formerly [[trackless trolleys]].<ref name=repairs /> Like the Red Line, it is split into two stacked tunnel levels; the northbound level is above and slightly east of the southbound level.<ref name=linesofthehub />{{rp|122}} Both levels have platforms on their east side, located under Brattle Street southwest of the main lobby. A pair of ramps connect the main station lobby to the platforms; a small set of stairs also connects the lower platform to the west side of the lobby. A headhouse and an elevator to the upper level are located at Eliot Square at the southwest end of the platform.<ref name=eliot />

The south portal of the tunnel is located on Mount Auburn Street; it runs slightly west of Brattle Street to Harvard Square, then northward along the west side of Massachusetts Avenue. The north portal is located inside Flagstaff Park near the south end of [[Cambridge Common]], with an incline to the intersection of Massachusetts Avenue and Cambridge Street.<ref name=linesofthehub>{{cite book |title=Streetcar Lines of the Hub - The 1940s |last=Clarke |first=Bradley H. |year=2003 |publisher=Boston Street Railway Association |isbn=0938315056}}</ref>{{rp|121}} Bennett Alley, a private alley south of Mount Auburn Street, is used for layovers and for northbound buses to access the tunnel from Bennett Street.<ref>{{cite news |url=https://www.thecrimson.com/article/2014/2/27/construction-governor-auburn-development/|title=Construction Begins on $65 Million Development in Square |newspaper=Harvard Crimson |date=February 27, 2014 |first1=Ivan B. K. |last1=Levingston |first2=Celeste M. |last2=Mendoza}}</ref><ref name=linesofthehub />{{rp|123}}

The platform is located on the left side for southbound buses (all of which terminate at Harvard). Because buses using the tunnel do not have left-hand doors, passengers must alight next to the wall and cross in front of the bus.<ref name=safari /> MBTA trolleybuses were equipped with an additional left-hand door for boarding on this level; because this door did not have a farebox, passengers instead paid while alighting from routes 71 and 73 (the only routes that boarded southbound in the tunnel).<ref>{{cite web |url=http://thebsra.org/bsra/wp-content/uploads/2016/03/2014-08-02.pdf |title=Entertainment Report for August 2, 2014 (Boston Transit Memories: The Road to the Green Line) |publisher=Boston Street Railway Association |first=Bradley |last=Clarke |date=August 2, 2014}}</ref><ref name=safari>{{cite magazine |last=Priestley |first=John |date=July–August 1988 |title=North American Safari: Part 3 |magazine=Trolleybus Magazine |pages=83–88 |publisher=National Trolleybus Association (UK) |issn=0266-7452}}</ref>

Harvard is a major transfer point for MBTA bus routes. {{MBTA bus links/count|Harvard Bus Tunnel|upper}} routes{{nbsp}}— {{MBTA bus links|Harvard Bus Tunnel|yes}}{{nbsp}}— use the Harvard bus tunnel. All board on the upper level; all use the lower level for alighting except the 71 and 73 (which use the upper level for alighting) and the southbound 66, 86, and 109. {{MBTA bus links/count|Harvard Square|upper}} routes – {{MBTA bus links|Harvard Square|yes}} – stop at street level at several locations in Harvard Square. (Routes 66, 86, and 109 run northbound in the tunnel and southbound on the surface.) {{MBTA bus links/mapcite}} Southbound buses on routes 66 and 86, and terminating buses on route 77, also serve a stop on Eliot Street at Bennett Street.<ref name=netransit />{{MBTA bus links/mapcite|ref}}

== History ==
===Original station===
[[File:Harvard station 1912.jpg|thumb|left|A train at the original Harvard station in 1912]]
[[Horsebus|Horse-drawn omnibus]] service between [[Harvard Square]] in [[Cambridge, Massachusetts|Cambridge]] and downtown Boston began in 1826. The hourly service soon increased to ten-minute headways to meet demand.<ref name=redlinebook />{{rp|6}} In late 1849, the [[Fitchburg Railroad]] opened the [[Harvard Branch Railroad]], with a Harvard Square station near where [[Austin Hall (Harvard University)|Austin Hall]] is now located. With only six daily round trips, the branch failed to compete with the omnibus service and was closed in 1855.<ref>{{cite book |title=Boston's Depots and Terminals |first=Richard C. |last=Barrett |publisher=Railroad Research Publications |isbn=1884650031 |year=1996 |page=214}}</ref><ref name=sne>{{cite book |title=The Rail Lines of Southern New England |edition=2 |last=Karr |first=Ronald Dale |publisher=Branch Line Press |year=2017 |isbn=9780942147124 |page=252}}</ref> On March 26, 1856, the [[Cambridge Railroad]] began [[horsecar|horse-drawn tram]] service between Harvard Square and [[Bowdoin Square]]{{nbsp}}— the first such service in the Boston area.<ref name=redlinebook />{{rp|6}} Following the opening of its [[Green Line C branch|Beacon Street line]] earlier that year, the [[West End Street Railway]] began electric streetcar service on the North Cambridge–Bowdoin Square line on February 16, 1889.<ref name=redlinebook />{{rp|6}} Murray Street Carhouse was built for the new electric cars.<ref name=redlinebook />{{rp|24}} The West End (which was acquired by the [[Boston Elevated Railway]] in 1897) rapidly expanded its electric operations, including other lines meeting at Harvard Square.<ref name=redlinebook />{{rp|6}}

After the success of the 1897-opened [[Tremont Street Subway]], the Boston Elevated Railway (BERy) planned an elevated system with lines to Cambridge, [[South Boston]], [[Charlestown, Boston|Charlestown]], and [[Roxbury, Boston|Roxbury]]. The latter two lines opened in 1901 as the [[Charlestown Elevated]] and [[Washington Street Elevated]], while the South Boston line was determined to be infeasible.<ref name=redlinebook>{{cite book |title=Boston's Red Line: Bridging the Charles from Alewife to Braintree |last=Cheney |first=Frank |year=2002 |publisher=[[Arcadia Publishing]]|isbn=9780738510477}}</ref>{{rp|7}} After debate about running an elevated line above business districts in Cambridge, the BERy agreed in late 1906 to build a line under [[Beacon Hill (Boston)|Beacon Hill]] in Boston, over a new [[Longfellow Bridge|West Boston Bridge]], and under Main Street and Massachusetts Avenue in Cambridge to Harvard Square.<ref name=redlinebook />{{rp|7}} Construction began on May 24, 1909.<ref name=redlinebook />{{rp|7}} The Cambridge Subway opened from Harvard Square to [[Park Street station (MBTA)|Park Street Under]] on March 23, 1912, with intermediate stations at [[Central station (MBTA)|Central Square]] and [[Kendall/MIT station|Kendall Square]].<ref name=netransit />

The two-level underground Harvard Square station largely matched the triangular shape of Harvard Square. The subway platforms were oriented east-west under Massachusetts Avenue at the east end of the station, with the outbound (unloading) platform above and slightly north of the inbound platform.<ref name=engnews /> The outbound platform was {{convert|283|feet}} long and at least {{convert|10-12|feet}} wide; the inbound platform was {{convert|320|feet}} long and at least {{convert|20|feet}} wide to accommodate passengers waiting for trains.<ref name=erj /> West of the platforms, the tracks merged onto a single level, with a [[pocket track]] between them. This three-track tunnel ran southwest under Brattle Street to a maintenance facility known as [[#Maintenance facilities|”Eliot Shops”]]; outbound trains could reverse direction at the pocket track or continue to the yard.<ref name=engnews />

A two-level streetcar tunnel formed the west part of the station, with platforms {{convert|435-472|feet}} long.<ref name=erj /> The southbound (lower) level was for streetcars running on Mount Auburn Street, while the northbound level was for streetcars running on Massachusetts Avenue and Garden Street. The streetcar platforms were divided into unloading and loading sections for the [[#Streetcar tunnel|through-routed streetcar lines]], allowing separation of passenger flows in opposite directions.<ref name=erj /> This philosophy was used throughout the station, with dedicated one-way transfer passages between trains and streetcars in all directions. All passages were level or sloped downwards for ease of movement, and stairs were only necessary for entering or exiting the station at the surface.<ref name=erj /><ref>{{cite magazine |url=https://books.google.com/books?id=WxY6AQAAMAAJ&pg=PA491 |title=The Cambridge Subway |magazine=[[Electric Railway Journal]]|date=March 30, 1912 |volume=39 |issue=13 |page=491|via=Google Books}}</ref> The platforms and floors were made of [[granolithic]]. Station walls were tiled with white enamel, with a red tile band {{convert|6|feet}} above the floor and white plaster above.<ref name=engnews /> The exit to Harvard Yard also had dark granite inside and black marble at the surface.<ref name=erj />

Early plans called for a monument-like headhouse in Harvard Square matching that of [[Government Center station (MBTA)#History|Scollay Square station]].<ref name=redlinebook />{{rp|20}} However, a one-story, {{convert|40x60|feet|adj=on}} oval-shaped brick and stone entrance/exit structure was constructed instead.<ref name=erj /> Like the rest of the Cambridge Subway, it was designed by a committee of architects led by [[Robert Swain Peabody|Robert Peabody]].<ref name=landmark>{{cite web |url=https://www.cambridgema.gov/CDD/Projects/Parks/~/media/A5D25CF4DB044374B4ABBD454E38391C.ashx |title=Final Landmark Designation Report: Harvard Square Kiosk |first=Charles |last=Sullivan |publisher=Cambridge Historical Commission |date=November 30, 2017}}</ref><ref name=erj /><ref name=redlinebook />{{rp|31}} Additional entrances were located on the south side of Massachusetts Avenue east of Holyoke Street, and inside a BERy waiting room on the south face of the square.

===Streetcar tunnel===
With an eight-minute running time between Harvard Square and Park Street, the Cambridge Subway was fifteen minutes faster than surface streetcars.<ref>{{cite news |url=https://www.newspapers.com/clip/47433037/the-boston-globe/ |title=Cambridge Subway to Save Suburbanites a Lot of Time Journeying to and from Boston |newspaper=Boston Globe |date=March 20, 1912 |page=16 |via=Newspapers.com}} {{open access}}</ref> No longer needing to run to downtown Boston, lines from the north and west were truncated to Harvard Square.

Bus routes added in the 1920s and 1930s (including the 1925 conversion of the Harvard-Kendall line) originally stopped on the surface.

===Maintenance facilities===
The BERy constructed a pair of rail yards on a site to the southwest of Harvard Square, bordered by Eliot Street, Bennett Street, University Road, Charles River Road, and Boylston Street. Much of the site was occupied by BERy and [[West End Street Railway]] streetcar barns; the area had been used for horsecar facilities since at least 1871.<ref name=redlinebook />{{rp|23}} The rest of the site, which had once been marshland, was occupied by private buildings.<ref name=dec1964 /><ref>{{cite book |url=https://www.wardmaps.com/viewasset.php?aid=5487 |title=Atlas of The City of Cambridge |pages=Plates 17 and 22 |no-pp=yes |year=1903 |publisher=G.W.

{{Main|Arts on the Line}}
As a part of the [[Red Line Northwest Extension]], Harvard was included as one of the stations involved in the pioneering [[Arts on the Line]] program. Arts on the Line was 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 arrangements to fund public art across the country.<ref name="Extension">[http://www.davissquaretilesproject.com/artsontheline/pamphlet/5 Red Line Northwest Extension Pamphlet page 5]. The Davis Square Tiles Project. Accessed May 31, 2010</ref>

Four of the original twenty artworks were located at Harvard station.<ref name="Harvard">[http://www.cambridgema.gov/cac/public_art_tour/map_05_harvard.html Arts on the Line:Harvard Square MBTA Station] {{webarchive|url=https://web.archive.org/web/20110721034529/http://www2.cambridgema.gov/cac/public_art_tour/map_05_harvard.html |date=2011-07-21 }}. Cambridge Arts Council. 2002. Accessed May 30, 2010</ref> The first two are located within the station interior, while the remaining two were located outdoors:
* ''Blue Sky on the Red Line'' by [[György Kepes]]{{nbsp}}— A large [[stained-glass]] wall composed of mostly [[cobalt blue glass]], with the exception of a red band that runs the length of the work. It is mounted on the wall of the upper Harvard bus tunnel so that it is visible from the central atrium space of the station. The work was no longer lit by 1995 because the original light fixtures had expired.<ref>{{cite news |url=https://www.newspapers.com/article/the-boston-globe/139987640/ |title=Keeping art fit to a T |newspaper=The Boston Globe |date=May 28, 1995 |first=Christine |last=Temin |pages=B17, [https://www.newspapers.com/article/the-boston-globe/139987677/ B22] |via=Newspapers.com}}</ref> It required $40,000 of repairs in 1998.<ref>{{cite news |url=https://www.newspapers.com/clip/65653340/the-boston-globe/ |title=Art Stations |author=Tatiana With Ribadeniera |newspaper=Boston Globe City Weekly |date=August 2, 1998 |page=1 |via=Newspapers.com}} {{open access}}</ref> The backlighting for the artwork, which had not been functional for years, was restored in December 2019.<ref>{{cite news |url=https://www.universalhub.com/2020/illuminated-stained-glass-under-harvard-square |title=Illuminated stained glass under Harvard Square turned back on |author=adamg |newspaper=Universal Hub |date=January 3, 2020}}</ref><ref>{{cite web |url=https://inside.lighting/news/23-05/shining-night-boston-ies-gala |title=A Shining Night: The Boston IES Gala |date=May 12, 2023 |publisher=Inside Lighting}}</ref>
* ''New England Decorative Art'' by [[Joyce Kozloff]]{{nbsp}}— An {{convert|83|ft|m|adj=on}} long mosaic split up into 8 sections, each resembling a quilt.
* ''Gateway to Knowledge'' by [[Anne Norton]]{{nbsp}}— A {{convert|20|ft|m|adj=on}} high brick structure divided vertically down the center by a gap, but still attached at the top. One half is slightly forward of the other (located in Brattle Square).
* ''Omphalos'' by [[Dimitri Hadzi]]{{nbsp}}— A freestanding grouping of pillars made up of various shapes that intersect at odd angles using many different types and polishes of granite. Previously located just north of the news stand which is also north of the main station entrance, the sculpture was removed in 2013 due to deterioration, with plans to refurbish and relocate it elsewhere.
