# Boston-area streetcar lines

As with many large cities, a large number of Boston-area streetcar lines once existed, and many continued operating into the 1950s. However, only a few now remain, namely the four branches of the Green Line and the Mattapan Line, with only one (the Green Line E branch) running regular service on an undivided street.

## History

The first streetcar line in the Boston area was a horse-drawn line from Central Square, Cambridge to Bowdoin Square, Boston opened by the Cambridge Railroad on March 26, 1856. Over the following decade a large number of horsecar lines were built by different companies, including the Metropolitan Railroad, Middlesex Railroad, and South Boston Railroad; these companies competed with each other while also sharing tracks in many locations. By the mid-1860s horsecar lines reached to Lynn, Arlington, Watertown, Newton, West Roxbury, and Milton. In 1887 the various Boston-area horsecar companies (except for the Lynn and Boston Railroad) were all consolidated into the West End Street Railway.
In 1889 the West End Street Railway experimented with electric power for its streetcars; the results were so promising that it abandoned a cable car project already under construction. Several lines were electrified in 1889 and by 1895 almost the entire system had been electrified. The last horsecar line was abandoned in 1900.
In 1897 the recently-formed Boston Elevated Railway (BERy) took over the West End Street Railway in order to make the streetcar lines part of its planned rapid transit system. In 1897 the Tremont Street Subway opened and many streetcar routes that had previously used surface tracks in downtown Boston were rerouted into the subway. Over the following decades the opening elevated and underground rapid transit lines (which became today's Orange Line and Red Line), as well as extensions of the Tremont Street subway (which became the Green Line), allowed progressively more streetcar lines to be removed from the congested streets downtown and rerouted to rapid transit stations further out. Passengers could transfer for free between streetcars and rapid transit lines to complete their journeys to or from downtown.$^{:127}$ In 1904 the East Boston Tunnel opened and was initially used to allow streetcars from East Boston to reach downtown, but in 1924 it was converted into another rapid transit line (part of today's Blue Line) operated with free transfers to and from streetcars at Maverick station.
In the 1920s as competition from cars increased and bus technology improved, the BERy began replacing some of its streetcar lines with buses. These conversions accelerated in the 1930s, with some routes also converted to trolleybuses (locally referred to as 'trackless trolleys'). Bus conversions paused during World War II when gasoline and rubber were in limited supply, but resumed in the late 1940s.
In 1947 the Metropolitan Transit Authority (MTA) was formed to take over the streetcar, bus, and rapid transit operations of the Boston Elevated Railway. It continued to convert lines from streetcar (and trackless trolley) to bus. In 1964 the MTA's operations were in turn taken over by the Massachusetts Bay Transportation Authority (MBTA), which also took over other bus systems running to suburban towns outside the MTA area. By this point the only remaining streetcar lines were five routes running into the Tremont Street Subway and one route on private right-of-way between Mattapan and Ashmont at the end of the Red Line. These were respectively designated as the Green Line branches A thru E and as part of the Red Line. The Green Line "A" branch was subsequently abandoned in 1969 and the "E" branch south of Heath Street abandoned in 1985.

### Route numbering

In 1936, the BERy assigned numbers to its routes for map use, but route numbers were not used on buses until the late 1960s (when the colors were assigned to the remaining rail lines). Additionally, the numbers were only kept the same on and after the 1942 revision of the map; before that they were changed with each new version. A few routes were renumbered around 1967, but most routes have kept their original numbers even through conversions from streetcar to trackless trolley to bus. Routes were numbered roughly clockwise from South Boston to East Boston.

## Timeline of streetcar abandonments

This is a table of when each streetcar line was converted to trackless trolley or bus. Only information post-1940 is complete.

## MTA streetcar routes as of 1953

As of early 1953 the Metropolitan Transit Authority operated the following streetcar routes. All lines were connected via trackage to the Tremont Street subway (Green Line), but only the 9, 39, 43, 57, 61, 62 and 69 actually operated in the subway.
* 7 City Point–South Station via Summer Street: Ran essentially the same route from City Point to South Station as today's 7 bus, which replaced it in June 1953.
* 9 City Point–subway: Ran via Broadway to the Pleasant Street subway portal and through the subway to North Station. Replaced in December 1953 by the 9 bus from City Point to Broadway & Tremont Street, which was extended to Copley Square in 1975.
* 10 City Point–Dudley: Ran via Broadway, Dorchester Street, Southampton Street, Northampton Street and Washington Street to Dudley station (today known as Nubian station) on the Washington Street Elevated. Replaced in December 1953 by the 10 bus, which was rerouted via Boston Medical Center to Copley Square in 1987 due to the relocation of the southern Orange Line.
* 28 Mattapan–Ashmont: Today known as the Mattapan Line.
* 29 Mattapan–Egleston via Blue Hill Avenue and Seaver Street: Ran from Mattapan north on Blue Hill Avenue and Seaver Street (both parts of State Highway 28) to Egleston station on the Washington Street Elevated. Replaced in September 1959 by the 29 bus, which was extended to Jackson Square (with some trips continuing to Ruggles) in 1987 due to the relocation of the southern Orange Line.
* 30 Mattapan–Arborway via Cummins Highway: Ran from Mattapan along Cummins Highway and Hyde Park Avenue to Arborway station. Replaced in April 1953 by bus service with branches to both Arborway via Hyde Park Avenue (30A) and Roslindale Square via Cummins Highway (30). The 30A branch was discontinued in 1981, but since the 1990s most 30 trips have been extended via Washington Street to Forest Hills station.
* 32 Cleary Square–Arborway: Ran along Hyde Park Avenue. Replaced in April 1953 by the 32 trackless trolley, which was converted to bus in March 1963 and extended south to Wolcott Square in 1981.
* 39 Arborway–subway via Huntington Avenue: Ran along Centre Street, South Huntington Avenue, Huntington Avenue, and through the Huntington Avenue Subway and Boylston Street Subway to Park Street station. Became the Green Line E branch. Replaced in December 1985 by the 39 bus running between Forest Hills and Copley Square, but short-turn service from the subway to Brigham Circle was restored in July 1986 and to Heath Street in November 1989.
* 40 Arborway–Egleston via Washington Street: Ran under the Washington Street Elevated between Egleston station and Forest Hills station. Replaced in December 1955 by a bus route that was subsequently discontinued in June 1971. In April 1981 the 42 bus was extended to cover the former 40 route.
* 43 Egleston–subway: Ran from Egleston via Columbus Avenue and Tremont Street to the Pleasant Street subway portal and through the subway to North Station. Before December 1953, when route 9 operated into the same portal, the 43 used the two west tracks. Afterwards, it was realigned to use the two east tracks, allowing for a larger bus transfer area to the west. Replaced by the 43 bus in two stages, south of Lenox Street in June 1956 and north of Lenox Street to the subway portal in November 1961. The bus route was extended north to loop around Boston Common in June 1972, and had its south end truncated from Egleston to the new Ruggles station in 1987 due to the relocation of the southern Orange Line.
* 47 Massachusetts station–Dudley: Ran from Massachusetts Avenue station (now Hynes Convention Center station) south along Massachusetts Avenue, southwest one block on Columbus Avenue, southeast on Northampton Street and southwest on Washington Street beneath the elevated to Dudley station (today known as Nubian station). Replaced in September 1953 by bus service, which in September 1962 was merged with the 76 Harvard–Massachusetts station bus route to form the 1 bus from Harvard to Dudley.
* 57 Heath Street–subway: Today known as the Green Line E branch. Service south of Brigham Circle was temporarily suspended 1980-1982 and 1985-1989.
* 61 Cleveland Circle–subway: Today known as the Green Line C branch.
* 62 Cleveland Circle–subway: Today known as the Green Line B branch.
* 69 Watertown–subway: Ran along Galen Street, Washington Street (Newton), Park Street (Newton), Tremont Street (Newton/Brighton), Washington Street (Brighton), Cambridge Street (Brighton), North Beacon Street, Commonwealth Avenue, into the Blandford Street subway portal and through the Boylston Street Subway to Park Street station. Became the Green Line A branch. Replaced by the 57 bus from Watertown to Kenmore in June 1969.
* 71 Watertown–Harvard: Ran essentially the same route from Watertown to the Harvard station transit tunnel as today's 71 bus, which replaced it in September 1958 (as a trackless trolley until March 2022). See also Trolleybuses in Greater Boston#Harvard-based routes.
* 73 Waverley–Harvard: Ran essentially the same route from Waverley station to the Harvard station transit tunnel as today's 73 bus, which replaced it in September 1958 (as a trackless trolley until March 2022). See also Trolleybuses in Greater Boston#Harvard-based routes.
* 79 Arlington Heights–Harvard: Ran essentially the same route from Arlington Heights to the Harvard station transit tunnel as today's 77 bus, which replaced it in November 1955 (renumbered from 79 to 77 in the late 1960s).
* 82 North Cambridge–Harvard: Ran from North Cambridge carhouse to the Harvard station transit tunnel via Massachusetts Avenue. Replaced by a trackless trolley route in September 1958, which was renumbered 77A in the late 1960s. In January 2005 most service on the 77A route was eliminated but it continued to operate on trips to get trackless trolley vehicles between the carhouse and routes 71 and 73 until the latter routes were converted to buses in March 2022. See also Trolleybuses in Greater Boston#Harvard-based routes.
* 100 Elm Street–Sullivan via Fellsway: Ran from Elm Street on Fellsway West in Medford via Fellsway and Mystic Avenue to Sullivan station on the Charlestown Elevated. Track connections to the rest of the system were provided by the otherwise unused streetcar tracks under the elevated from Sullivan south to the Causeway Street incline, once used by route 92. Route 100 was replaced in December 1955 by the 100 bus, which was rerouted to Wellington station in 1975 due to the relocation of the northern Orange Line.

## Eastern Massachusetts Street Railway routes

The Eastern Massachusetts Street Railway (EMSR) operated lines between Boston and towns north and south of the Boston area, including Lynn, Salem, Reading, Lowell, Lawrence, Quincy, Hingham, and Brockton. It also operated local streetcar service within those towns. The company was formed in 1919 to take over the lines of the bankrupt Bay State Street Railway, which advertised itself as "the world's largest street railway system" in the 1910s.$^{:72}$ Between 1931 and 1937, EMSR replaced almost all of its streetcar routes with bus service. Only three streetcar lines were left by the end of 1937, all linking Boston to nearby towns.

### Stoneham–Sullivan

This streetcar line ran between Sullivan Square#Elevated station and Stoneham, Massachusetts. It left Sullivan operated by a Boston Elevated Railway driver and ran via the tracks of BERy's 100 line. It continued beyond from the north end of the 100 through the Middlesex Fells on a privateright-of-way west of Fellsway West. At a stop called "Sheepfold" near Spot Pond in Middlesex Fells, the operator was replaced by an EMSR employee who drove the streetcar the rest of the way into Stoneham and alongside Main Street to the terminal at Farm Hill Station of the Boston and Maine Railroad Stoneham Branch.
The line was bustituted in 1946. In 1968 the MBTA took the bus service over as the 430, and from March 1969 to the end of its service in September 1971, it was part of the 100A Reading–Sullivan via Main Street and Fellsway.

### Quincy routes

Two Quincy routes left Fields Corner station, running to Quincy center and then splitting. One line continued to Hough's Neck, and the other to Quincy Point and the Fore River Shipyard. The lines were bustituted in 1946 and 1948 respectively. The bus routes that replaced them eventually became MBTA routes 210, 216, and 220/222.
