The "B" Branch, also called the Commonwealth Avenue Branch or Boston College Branch, is a branch of the MBTA Green Line light rail system which operates on 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 Blandford Street. There, it enters Blandford Street Portal into Kenmore station, where it merges with the "C" and "D" branches. The combined services run into the Boylston Street Subway and Tremont Street Subway to downtown Boston. "B" Branch service currently terminates at Park Street; normally it runs to Government Center station which is undergoing renovations until 2016.

The Green Line Rivalry between Boston College and Boston University is named in reference to the "B" Branch, which runs to both colleges.

History[edit]

In 1896, tracks were laid on Commonwealth Avenue from Chestnut Hill Avenue west to the Newton town line at Lake Street, and around the same time the Commonwealth Avenue Street Railway opened, extending the tracks through Newton to Norumbega Park; this later became part of the Middlesex and Boston Street Railway. Trains between Lake Street and downtown Boston used tracks on Beacon Street, now part of the "C" Branch. From Kenmore Square they continued east on Beacon Street, then turned south on Massachusetts Avenue and east on Boylston Street to Park Square. In 1900 tracks were installed on the rest of Commonwealth Avenue, from Chestnut Hill Avenue east to existing tracks at Packard's Corner, later part of the "A" Branch. This enabled trains to use Commonwealth Avenue between Lake Street and Kenmore Square. In 1909, the tracks were electrified.[2]

The Tremont Street Subway opened on September 1, 1897 and then or soon after the Commonwealth Avenue line was rerouted to turn around at Park Street via the Boylston Street Incline at the Public Garden. The Boylston Street Subway opened on October 3, 1914, extending the underground portion to the Kenmore Incline just east of Kenmore Square. On October 23, 1932 the Blandford Street Incline opened along with the underground Kenmore station, giving the line its present configuration.

Until the 1920s, a streetcar line that has since become the 65 bus ran along Commonwealth Avenue from Boston College east to Chestnut Hill Avenue, then south on Chestnut Hill Avenue and east on Beacon Street from Cleveland Circle to Washington Square, turning southeast to Brookline Village. After this was replaced by bus service in the 1920s (along with a rerouting), no revenue service used the tracks on Chestnut Hill Avenue, but they have remained for "B" Branch trains to access the Reservoir Carhouse at Cleveland Circle on the "C" Branch.

A turnback loop at Boston University Field was present from 1915 to January 14, 1962. It was used for service to special events as well as to short-turn some rush hour trains.

From 1942 to 1967, the route was known by the map number of 62. In 1967, the lines were given colors and the Green Line branches were lettered. The Commonwealth Avenue Line became the "B" Branch.

Downtown terminal[edit]

Until 1931, the line always looped at Park Street. On February 7 of that year, the Commonwealth Avenue service was extended east through downtown to loop at Lechmere. Since then, the following changes in east terminal have been made:[3]

  • November 20, 1961: cut back to Park Street
  • November 18, 1964: extended Monday-Saturday to Government Center
  • January 1967: cut back to Park Street all times due to problems at the Government Center loop
  • March 25, 1967: extended to North Station
  • June 17, 1967: cut back to Government Center
  • September 9, 1967: extended to North Station
  • September 14, 1967: cut back to Government Center due to problems at the North Station loop
  • March 21, 1970: extended to Haymarket, looped empty at North Station
  • December 26, 1970: extended to North Station
  • March 25, 1974: extended to Lechmere
  • January 1, 1977: cut back to North Station weekdays only
  • March 19, 1977: extended to Lechmere all times
  • June 18, 1977: cut back to Government Center all times
  • September 9, 1977: extended to Lechmere all times
  • September 9, 1978: cut back to Government Center nights and Sundays
  • March 24, 1979: cut back to Government Center middays and Saturdays, with only rush hour trips continuing to Lechmere
  • March 21, 1980: cut back to Park Street all times
  • April 4, 1981: extended to North Station (PCC cars looped at Government Center)
  • July 30, 1983: cut back to Government Center

Speed[edit]

The B Branch is frequently criticized by riders for its slow service. It is markedly slower than the C branch, in part because of its greater density of stops and at-grade crossings. Like on its sister C branch, B branch streetcars must stop on traffic signals at street crossings. Both B and C line branches are slower than the D branch, which benefits from the lowest stop density and an exclusively dedicated right-of-way.

Mount Hood Road stop (outbound platform pictured) was closed in 2005

In late 2003, the MBTA proposed eliminating five stops along the B branch (Greycliff Road, Mount Hood Road, Summit Avenue, Fordham Road and Chiswick Road.) This was seen as a way to speed up service for riders, while also reducing the MBTA's maintenance costs.[citation needed] Many riders[who?] welcomed the change, noting the stops' low ridership and close proximity to more popular stops. Others[who?] felt that the change did not go far enough, noting that the total time savings would be small (a few minutes out of a 45-minute trip) and the B branch would still be the slowest Green Line branch by far. Many riders[who?] questioned why the MBTA did not propose closing any of the stops east of Packard's Corner, even though this would improve travel times for the largest number of riders and several of these stops are only several hundred feet apart.

In April 2004, four of the five stops (Greycliff Road, Mount Hood Road, Summit Avenue and Fordham Road) were closed in a pilot stop elimination program.[4] The fifth (Chiswick Road) was spared, after elderly residents of the nearby Jewish Community Housing facility rallied to its defense. In 2005, after a survey showed that 73% of 1,142 riders surveyed approved of the closures, the MBTA announced that the four stops would be closed permanently.[5] Despite these favorable and popular responses by B branch riders, the MBTA has no further plans to improve service times on the B branch, either by reducing stop frequency or using any other means, such as traffic signal prioritization.

Station listing[edit]

Trains on the "B" Branch only travel from Government Center to Boston College. The segment from Government Center to Kenmore is shared with the three other branches. There is no MBTA parking at any "B" Branch stations.
