Route 15 is a local bus route in Boston, Massachusetts, United States, operated by the Massachusetts Bay Transportation Authority (MBTA) as part of MBTA bus service. It operates between Ruggles station and Fields Corner station via Nubian station and Uphams Corner. It is among the highest-ridership routes on the system, with service every 15 minutes or less during all operating hours. Route 17 is a less-frequent route that operates between Andrew station and Fields Corner station. Between Fields Corner and Uphams Corner, it follows the same routing as route 15.
Most portions of routes 15 and 17 originated as horsecar lines built or acquired by the Metropolitan Railroad between 1856 and 1873. The West End Street Railway purchased and merged all the horse railroads in the Boston area in 1887. It electrified the Dudley Street and Meeting House Hill lines in 1893–94. Its successor, the Boston Elevated Railway (BERy), opened an extension of the Meeting House Hill line to Fields Corner in 1899 and re-opened a line to Andrew Square in 1901. The Washington Street Elevated opened in 1901, with some streetcar service terminated at Dudley Street Terminal rather than running to downtown Boston.
Extensions of the Cambridge–Dorchester Line to in 1917, in 1918, and Fields Corner in 1927 resulted in further changes. By the 1940s, service on Dudley Street consisted of a Dudley–Uphams Corner streetcar line (route 15), while service on Meeting House Hill consisted of an Andrew–Fields Corner streetcar line (route 17) and a belt line bus. The Metropolitan Transit Authority (MTA) replaced the BERy in 1947. It converted route 15 to trolleybuses in 1948 and route 17 in 1949. Routes 15 and 17 were converted to bus in 1962.
The Massachusetts Bay Transportation Authority (MBTA) replaced the MTA in 1964. Route 15 was extended to Ruggles in 1987 when the Southwest Corridor replaced the elevated. Weekend service was extended to Fields Corner in 2007. A number of stops on the route were closed in 2013 to reduce travel times. A 2018–19 MBTA review of its bus system found that routes 15 and 17 suffered from poor reliability. As part of systemwide network changes, all route 15 service was extended to Fields Corner in 2025.

History Early history
Most portions of what became routes 15 and 17 originated as horsecar lines. The Metropolitan Railroad opened a horsecar line between Dudley Square (now Nubian Square) and downtown Boston via Washington Street on September 17, 1856. A branch following Eustis Street, Davis Street (now Dearborn Street), and Dudley Street to the Roxbury/Dorchester border (Mount Pleasant) near Shirley Street opened on November 17, 1856. It was extended slightly to a carhouse at Burrell Street in 1865. Connecting track on Dudley Street between Dudley Square and Dearborn Street was opened on May 12, 1873, by the Highland Railway to reach its line on Blue Hill Avenue.
In May 1860, the Dorchester Extension Railway built the Meeting House Hill line from Andrew Square to Washington Street in Dorchester via Boston Road, Hancock Street, and Bowdoin Street. The portion south of Geneva Avenue was later abandoned. The Metropolitan acquired the Dorchester Extension in October 1863. On December 18, 1873, the Metropolitan extended its Mount Pleasant line to Uphams Corner, where it connected to the Meeting House Hill line. The former line was later abandoned north of Uphams Corner, with all service from Meeting House Hill operating via Mount Pleasant. Later in the 1870s, the company built a carhouse and stables at Mount Pleasant.
The Metropolitan opened a line east from Uphams Corner to Dorchester Avenue via Stoughton Street, Pleasant Street, and Savin Hill Avenue on November 15, 1880. The West End Street Railway purchased and merged all the horse railroads in the Boston area in 1887. By that time, three services ran to downtown Boston via Dudley Street: from Fields Corner via Dorchester Avenue every 20 minutes, from Meeting House Hill every 15 minutes, and from Uphams Corner every 6–10 minutes. After consolidation, the West End used paint color to differentiate cars on its various lines. Those on the Mount Pleasant, Meeting House Hill, and Dorchester Avenue lines were painted ultramarine blue with gold trim.
The West End began electrifying its system in 1889. Dudley Street was electrified between Dudley Square and Blue Hill Avenue on December 12, 1891, as part of a line to Grove Hall via Blue Hill Avenue. Uphams Corner service via Dudley Street was electrified on January 5, 1893; horsecar shuttle service operated between Meeting House Hill and Uphams Corner. Electric service was extended to Meeting House Hill on May 14, 1893. On July 28, 1894, the West End started a new electric streetcar line between Fields Corner and downtown Boston via Dorchester Avenue and Uphams Corner, inaugurating electric service on the 1880-built extension. The Meeting House Hill line was extended on Bowdoin Street to Washington Street by mid-1896. Service ran from the Ashmont Street Carhouse to North Union Station.
Streetcar changes
The first phase of the Tremont Street subway, a streetcar tunnel in downtown Boston, opened on September 1, 1897. Routes on Boylston Street could enter the subway through the Boylston Street portal to reach Park Street station. "Crosstown" routes from Fields Corner and Meeting House Hill, which used Massachusetts Avenue and Huntington Avenue to reach Boylston Street, were redirected into the subway at that time. On October 1, 1897, the Boston Elevated Railway (BERy) acquired the West End Street Railway. Track on Geneva Avenue between Bowdoin Street and Fields Corner opened on June 1, 1899. The Meeting House Hill crosstown service was rerouted to terminate at Fields Corner rather than Ashmont. A streetcar line on Columbia Road and Boston Street opened on June 22, 1901, using a short section of existing tracks through Uphams Corner.
The Main Line Elevated opened on June 10, 1901, with Dudley Street Terminal as the southern terminus of the Washington Street Elevated. Some streetcar routes terminated at Dudley, where passengers could transfer to the faster elevated trains, while others continued to operate into the downtown subway. By 1907, routes operated to Dudley via Uphams Corner from Park Street Carhouse (via Geneva Avenue), Adams Village (via Dorchester Avenue), and Neponset (via Dorchester Avenue). Two crosstown routes operated to Park Street station in the subway via Uphams Corner, Dudley, and Back Bay: from Park Street Carhouse via Geneva Avenue (some trips via Dorchester Avenue), and from Milton via Savin Hill.
Service on the Meeting House Hill line in 1917 included a Fields Corner–Essex Street route with off-peak frequency of every 20 minutes, a Fields Corner–Dudley route operating every 10 minutes, a Norfolk Street–Essex Street route operating every 20 minutes, and an Ashmont Carhouse–Rowes Wharf route via South Boston operating every 10 minutes. Service operating on Dudley Street included the Fields Corner–Dudley route, a Milton–Park Street crosstown route via Savin Hill operating every 10 minutes and a Neponset–Dudley route via Savin Hill operating every 5 minutes. On December 15, 1917, the Cambridge–Dorchester Line was extended south to Broadway station in South Boston. Many Dorchester streetcar routes were redirected to Broadway station. The Meeting House Hill line was served by a Fields Corner–Broadway route and a Milton–Broadway route via Washington Street. The Milton crosstown line was discontinued, leaving only the Neponset–Dudley line on most of Dudley Street.
On January 26, 1918, the BERy increased Dorchester streetcar service in response to overcrowding. This included establishment of a Meeting House Hill route from Bowdoin Street and Geneva Street to Dudley, operating every four minutes at peak and every ten minutes off-peak. The Cambridge–Dorchester Line was extended again to Andrew station on June 29, 1918; streetcar routes were cut back to Andrew station from Broadway. The Neponset line was redirected to Andrew; a new Fields Corner–Dudley route via Savin Hill began service. The Fields Corner–Dudley route was extended to Massachusetts station via Washington Street and Massachusetts Avenue on October 16, 1920.
In late 1920, the Dudley Street line was used by three services: the Massachusetts–Fields Corner route, operating every four minutes at peak and every 7–8 minutes at other times; the Dudley–Bowdoin and Geneva route, operating every 10 minutes at peak and every 20 minutes at other times; and a peak-only Dudley–Uphams Corner route operating every four minutes. The Meeting House Hill line was served by the Dudley–Bowdoin and Geneva route; the Andrew–Fields Corner route, operating every four minutes at peak (as two-car trains, with a streetcar pulling an unpowered trailer car) and every twelve minutes at other times; and the Andrew–Milton route, operating every six minutes at peak and every 12 minutes at other times.
