The '''B branch''', also called the '''Commonwealth Avenue branch''' or '''Boston College branch''', is a branch of the [[MBTA]] [[Green Line (MBTA)|Green Line]] light rail system which operates on [[Commonwealth Avenue (Boston)|Commonwealth Avenue]] west of downtown [[Boston]], [[Massachusetts]]. One of four branches of the Green Line, the B branch runs from [[Boston College station]] down the median of Commonwealth Avenue to {{bts|Blandford Street}}. There, it enters Blandford Street portal into [[Kenmore station]], where it merges with the [[Green Line C branch|C]] and [[Green Line D branch|D]] branches. The combined services run into the [[Boylston Street subway]] and [[Tremont Street subway]] to downtown Boston. B branch service has terminated at {{bts|Government Center}} since October 2021. Unlike the other branches, B branch service runs solely through the city limits of Boston. The [[Green Line Rivalry]] between [[Boston College]] and [[Boston University]] is named in reference to the B branch, which runs to both universities.

{{As of|February 2023}}, service operates on 8-minute headways at weekday peak hours and 8- to 12-minute headways at other times, using 9 to 15 trains (18 to 30 light rail vehicles).<ref>{{cite magazine |magazine=Rollsign |publisher=[[Boston Street Railway Association]] |date=January–February 2023 |issue=1–2 |volume=59 |title=MBTA Vehicle Inventory as of February 28, 2023 |first=Jonathan |last=Belcher |page=10}}</ref>

The first sections of what is now the B branch to open were built for what became the [[Green Line A branch|Watertown Line]] and [[Green Line C branch|Beacon Street Line]]. In 1889, the [[West End Street Railway]] opened the Beacon Street Line, including a branch that ran from [[Coolidge Corner]] to [[Oak Square]] along Harvard Avenue, Brighton Avenue, Cambridge Street, and Washington Street.<ref name=century>{{cite book |title=Tremont Street Subway: A Century of Public Service |last1=Clarke |first1=Bradley H. |last2=Cummings |first2=O.R. |year=1997 |publisher=Boston Street Railway Association |isbn=0938315048}}</ref>{{rp|58}} While this route provided service to the fast-growing suburbs of Allston and Brighton, a more direct route was desirable. When [[Commonwealth Avenue, Boston|Commonwealth Avenue]] was improved between [[Kenmore Square|Governors Square]] and [[Packards Corner|the junction with Brighton Avenue]] in the mid-1890s, a {{convert|33|feet|adj=on}}-wide median was included for use by a streetcar line to support real estate development.<ref name=cityengineer>{{cite book |url=https://books.google.com/books?id=lxZbAAAAYAAJ&pg=PA131 |title=Annual Report of City Engineer |pages=131–137 |edition=28 |year=1895}}</ref> Service began from Governors Square to Brighton Avenue, and along Brighton Avenue to connect with the older trackage at {{bts|Union Square|Green|A}}, on May 18, 1896.<ref>{{cite book |url=https://archive.org/stream/annualreporto18831921west#page/n225/mode/2up |title=Ninth Annual Report of the West End Street Railway Company for the Year Ending September 30, 1896 |page=5 |year=1896 |publisher=Walker, Young & Co |via=Internet Archive}}</ref><ref>{{cite news |url=https://www.newspapers.com/clip/59417143/the-boston-globe/ |title=New Electric Line |newspaper=Boston Globe |via=Newspapers.com}} {{open access}}</ref><ref name=century />{{rp|48}} (That line was extended to near [[Newton Corner station|Nonantum Square]] on June 13, 1896.)<ref name=century />{{rp|48}}

East of Governors Square, the Beacon Street line originally ran on Beacon Street, [[Massachusetts Avenue (Boston)|Massachusetts Avenue]], and [[Boylston Street (Boston)|Boylston Street]] to [[Park Square (Boston)|Park Square]].<ref name=century />{{rp|54}} By the time the Commonwealth Avenue segments opened, streetcars continued along heavily congested tracks on Tremont Street (electrified in 1891) to reach the [[North Station#History|northern railroad terminals]].<ref name=century />{{rp|61}} Both the Nonantum Square and Lake Street lines were rerouted into the [[Tremont Street subway]] to terminate at [[Park Street station (MBTA)|Park Street station]] soon after the tunnel's September 1, 1897 opening.<ref name=century />{{rp|21}}

The [[Boston Elevated Railway]] (BERy) leased the West End Street Railway on October 1, 1897, and continued its system expansion.<ref name=century />{{rp|35}} The BERy opened new tracks on Commonwealth Avenue from Chestnut Hill Avenue to Brighton Avenue on May 26, 1900, allowing direct service from Lake Street to downtown via Commonwealth Avenue. Even though much of the land surrounding Commonwealth Avenue in Brighton was not yet developed, the new line was heavily patronized.<ref name=century />{{rp|58}} For most of its length, the 1900-built trackage was not in a center median, but in a reservation between the southbound travel lane and southbound [[frontage road|carriage lane]]. Between {{bts|Warren Street}} and [[Chiswick Road station|Wallingford Road]], the reservation was significantly wider than the tracks.<ref>{{cite web |url=https://www.wardmaps.com/viewasset.php?aid=8481 |title=Atlas of the City of Boston: Ward 25, Brighton |year=1909 |publisher=G.W.

The Commonwealth Avenue line served two major baseball stadiums: [[Fenway Park]] (opened 1912) near Governors Square, and [[Braves Field]] (opened 1915) in Allston.

[[File:Map of 1926 proposal for Boston rapid transit lines.png|thumb|left|Map of the 1926 proposal]]
In June 1922, the BERy proposed to operate the inner part of the Commonwealth Avenue line as a rapid transit service. Three-car trains of recently acquired center-entrance cars, which had higher capacity and shorter dwell times than older streetcars, would run on headways as low as two minutes at rush hour and four minutes at other times.<ref name=1922plan /><ref name=century />{{rp|59}} A terminal stations would be built at Linden Street (near {{bts|Harvard Avenue}}) in Allston, where passengers would transfer between the subway trains and surface streetcar lines.<ref name=1922plan>{{cite magazine |url=https://books.google.com/books?id=ZF8_AQAAMAAJ&pg=PA951 |magazine=Electric Railway Journal |page=951 |title=New Prepayment Station in Boston |date=June 10, 1922 |volume=59 |issue=23}}</ref> The [[Lechmere station|Lechmere Square]] in East Cambridge (already under construction) opened that July, but local opposition to the forced transfer caused the Linden Street terminal plan to be scrapped.<ref name=century />{{rp|59}}

The congestion at busy Governors Square caused numerous delays to the streetcar lines. In May 1924, the state legislature directed the [[Department of Conservation and Recreation|Metropolitan District Commission]] to plan an expanded rapid transit system in Boston, including an extension of the Boylston street Subway under Governors Square.<ref>{{cite book |url=https://archive.org/details/actsresolvespass1924mass |title=Acts and resolves passed by the General Court of Massachusetts in the year 1924 |pages=[https://archive.org/details/actsresolvespass1924mass/page/602 602]–603 |chapter=Chapter 45: Resolve providing for an investigation by the Division of Metropolitan Planning relative to the extension and development of rapid transit service in Boston, Somerville and surrounding cities and towns |date=May 24, 1924 |via=Internet Archive}}</ref> The report, released in December 1926, called for the existing streetcar tunnels in Boston to be reorganized into two rapid transit lines with high-floor rolling stock.<ref name=1926report >{{cite book |title=Report on Improved Transportation Facilities in Boston |date=December 1926 |publisher=Division of Metropolitan Planning |hdl = 2027/mdp.39015049422689}}</ref> One line was to run from [[East Boston]] to Brighton, with the [[Blue Line (MBTA)|East Boston Tunnel]] (which had been converted from streetcars to rapid transit in 1924) realigned to connect with the Tremont Street subway near Park Street station.

The subway under Governors Square was projected to cost $5 million (equivalent to ${{Inflation|US|5|1926|r=0}} million in {{Inflation/year|US}}). The BERy and the city objected to this cost and proposed a $1.4 million plan where flyover ramps would separate Beacon Street auto and streetcar traffic from other traffic in the square.<ref>{{cite magazine |url=https://archive.org/stream/electricrailwayj68mcgrrich#page/898/mode/2up |title=Planning Board Agrees with Boston Elevated |page=899 |magazine=Electric Railway Journal |date=November 13, 1926 |volume=68 |issue=20}}</ref> The tunnel was eventually chosen but construction did not begin until 1930, after the legislature lowered the cost that the BERy would pay to rent the subway from the city.<ref name=1930btd>{{cite book |url=https://archive.org/details/annualreport1930trans |title=Annual Report of the Transit Department of the City of Boston |year=1930 |pages=[https://archive.org/details/annualreport1930trans/page/n8 1]–4 |publisher=Boston Transit Department |via=Internet Archive}}</ref> [[Kenmore station]] and the new subway, which split to separate portals at {{bts|Saint Mary's Street}} on Beacon Street and {{bts|Blandford Street}} on Commonwealth Avenue, opened on October 23, 1932.<ref>{{cite book <!--Deny Citation Bot--> |url=https://archive.org/details/annualreportofpu32bost |title=Annual report of the public trustees of the Boston Elevated Railway |publisher=Boston Elevated Railway |page=[https://archive.org/details/annualreportofpu32bost/page/14 14] |edition=14 |via=Internet Archive}}</ref><ref name=century />{{rp|59}} The extension was built to support future rapid transit conversion of the Commonwealth Avenue line, including extension of the underground section further west.<ref name=1930btd /><ref name=century />{{rp|44}}

Interest in converting the Commonwealth Avenue line to rapid transit declined as focus shifted to expanding the subway to further suburbs. The 1945 and 1947 Coolidge Commission reports (the next major planning effort after the 1926 report) instead recommended a parallel rapid transit line along the [[Boston and Albany Railroad]] corridor, with local streetcar service retained on Commonwealth Avenue.<ref>{{citation |title=Air View: Present Rapid Transit System – Boston Elevated Railway and Proposed Extensions of Rapid Transit into Suburban Boston |date=April 1945 |author1=Boston Elevated Railway |author2=Massachusetts Department of Public Utilities |title-link=:commons:File:1945 BERy extensions map.jpg |via=Wikimedia Commons}}</ref><ref name=linesofthehub />{{rp|16}} However, several smaller improvements were made to the line.

In the early 1940s, the BERy began replacing its older streetcars with the [[PCC streetcar]].

In August 1964, the [[Massachusetts Bay Transportation Authority]] (MBTA) replaced the MTA. As part of systemwide rebranding efforts, the remaining streetcar routes feeding the Tremont Street subway became the [[Green Line (MBTA)|Green Line]] on August 26, 1965.<ref name=netransit>{{NETransit}}</ref> In 1967, the five branches were given letters to distinguish them; the Boston College line became the B branch. (The Watertown line became the [[Green Line A branch|A branch]], while the Beacon Street line became the [[Green Line C branch|C branch]].)<ref name=netransit /> The MBTA experimented with changing the downtown terminals of the Green Line branches (unlike its predecessors, which had changed the downtown terminal of the Boston College line just twice.) The B branch was extended to the new loop at {{bts|Government Center}} opened on November 18, 1964 – the first service to regularly use the loop.<ref name=netransit /> Over the next two decades, the downtown termini were frequently changed; the B branch variously terminated at Park Street, Government Center, {{bts|Haymarket}}, [[North Station (subway)|North Station]], and Lechmere. On July 30, 1983, the terminus was finally changed to Government Center station, where it would stay until 2004.<ref name=netransit />

On June 21, 1969, the A branch was replaced with [[57 (MBTA bus)|Watertown–Kenmore buses]], halving streetcar service on Commonwealth Avenue east of Packard's Corner.<ref name=netransit /><ref name=century />{{rp|48}} In 1970, the median was moved slightly south between Chestnut Hill Avenue and Lake Street.<ref>{{cite news |url=https://www.newspapers.com/clip/52690767/the-boston-globe/ |title=Ask the Globe |newspaper=Boston Globe |date=February 18, 1970 |page=2 |via=Newspapers.com}} {{open access}}</ref><ref>{{cite news |url=https://www.newspapers.com/clip/52690803/the-boston-globe/ |title=Korea's Kim looms challenge in Marathon |first=Francis |last=Rosa |newspaper=Boston Globe |date=April 17, 1970 |page=29 |via=Newspapers.com}} {{open access}}</ref> The westbound roadway was lowered several feet below the median between South Street and Greycliff Road, with the Foster Street stop moved {{convert|500|feet}} west to the {{bts|Greycliff Road}} grade crossing.<ref name=sindel /> Around 1975, the stop at University Road was discontinued, while the stop at Alcorn Street was moved 500 feet east to {{bts|Babcock Street}}.<ref name=sindel />

The downtown terminus was extended to North Station on June 25, 2004, but cut back to Government Center on January 1, 2005.

===Accessibility and stop consolidation===
[[File:Inbound train passing former Mount Hood Road station, August 2016.JPG|thumb|left|Mount Hood Road stop (outbound platform pictured) was closed in 2004.]]
The introduction of low-floor LRVs in 2000 allowed for [[accessible]] service on the Green Line. In the early 2000s, the MBTA modified key surface stops with raised platforms as part of the [[Green Line (MBTA)#Light Rail Accessibility Program|Light Rail Accessibility Program]]. [[Wheelchair lift|Portable lift]]s were installed at {{bts|Boston College}} and {{bts|Boston University Central}} around 2000.<ref name=PMTaccess>{{cite web |archive-url=https://web.archive.org/web/20120220063458/http://www.bostonmpo.org/bostonmpo/pmt-old/PMT-1.pdf |archive-date=February 20, 2012 |url=http://www.bostonmpo.org/bostonmpo/pmt-old/PMT-1.pdf |title=Executive Summary |work=Program of Mass Transportation |date=January 2004 |publisher=Boston Regional Metropolitan Planning Organization |page=2-9}}</ref><ref>{{cite web |archive-url=https://web.archive.org/web/20010701041753/http://www.mbta.com/text-only/schedmaps/map/map.pdf |archive-date=July 1, 2001 |url=http://www.mbta.com/text-only/schedmaps/map/map.pdf |title=Subway Map |date=2001 |publisher=Massachusetts Bay Transportation Authority}}</ref> Four surface stops – {{bts|Boston University East}}, Boston University Central, {{bts|Harvard Avenue}}, and {{bts|Washington Street}} – were modified with raised platforms in 2002–03; Boston College was similarly modified in 2009.<ref name=globe2012>{{cite news |url=http://www.boston.com/yourtown/news/allston_brighton/2012/09/mbta_to_hold_meeting_on_20m_pr.html |title=MBTA to hold meeting on $20m project to rebuild Boston College Station |newspaper=Boston Globe |date=28 September 2012 |author=Rocheleau, Matt |archive-url=https://web.archive.org/web/20121001202632/http://www.boston.com/yourtown/news/allston_brighton/2012/09/mbta_to_hold_meeting_on_20m_pr.html |archive-date=October 1, 2012}}</ref><ref name=PMTaccess />

{{anchor|Former stops|former stops}}
The B branch is frequently criticized by riders for its slow service, with a high number of stops and level crossings. Until 2004, the line had 22 stops on the surface section, while the C and D branches had 13 each and the E branch just 9.<ref name=ctps /> In late 2003, the MBTA proposed eliminating five surface stops (Greycliff Road, {{bts|Chiswick Road}}, Mount Hood Road, Summit Avenue, and {{bts|Fordham Road}}) as part of a project to improve the line. The five stops were chosen because they had low ridership and were located very close to other stations.<ref name=drops /> <!--No stops east of Packards Corner were chosen, although they would affect the largest number of riders; despite their close spacing, they had higher ridership, and their proximity to traffic lights lowered the travel time savings from elimination. -->After a public comment period, Chiswick Road was removed from the proposal, as it served a nearby elderly housing community.<ref name=drops /> On April 20, 2004, the other four stops were closed as a 6-to-8-month pilot program.<ref name=ctps>{{cite web |archive-url=https://web.archive.org/web/20101126012518/http://ctps.org/bostonmpo/4_resources/2_transreport/archive/trpt0504.pdf |url=http://ctps.org/bostonmpo/4_resources/2_transreport/archive/trpt0504.pdf |archive-date=November 26, 2010 |title=Green Line B Branch Service Enhancements |work=TRANSreport |publisher=Boston Regional Metropolitan Planning Organization |date=May 2004}}</ref> On March 15, 2005, after a survey showed that 73% of 1,142 riders surveyed approved of the closures, the MBTA board voted to make the closures permanent.<ref name=drops>{{cite news |url=http://www.boston.com/news/local/articles/2005/03/16/t_drops_4_green_line_stops_after_results_of_rider_survey?mode=PF |title=T drops 4 Green Line stops after results of rider survey |newspaper=Boston Globe |date=March 16, 2005 |archive-url=https://web.archive.org/web/20050318030644/http://www.boston.com/news/local/articles/2005/03/16/t_drops_4_green_line_stops_after_results_of_rider_survey/ |archive-date=March 18, 2005 |author=Daniel, Mac}}</ref>
