BMT Jamaica Line

The Jamaica Line includes a variety of structures. The original BMT Jamaica Line started from Broadway Ferry, Brooklyn. The line was two tracks, and connected with Marcy Avenue, from the west. This section, which was called the "Broadway Spur", has a short, but easily seen remnant (about one-half of a block in length, no tracks, just maintenance buildings) west and south of where the line curves toward the Williamsburg Bridge. but engineering studies completed after the work started indicated that the vibration of trains passing over the stations would be too severe and would literally shake the stations apart. Between Crescent Street station and Cypress Hills, the line runs on an "S-curve", turning north from Fulton Street onto Crescent Street, then east onto Jamaica Avenue. The curves are at nearly 90-degree angles, forcing trains to drastically reduce speed to 15 miles per hour in order to traverse them. but a center track was never built (see below), with the exception of a layup track at 111th Street and another between 160th Street and 168th Street on the now-demolished original end of the line. Four curves on the line, including the two on the Jamaica Avenue "S-curve", are among the 30 sharpest curves in the subway system. The curve west of Marcy Avenue has radii of for Manhattan- and Queens-bound trains, respectively. The curve from Broadway Junction to Alabama Avenue has a radius of . The curve east of Crescent Street has radii of and the curve west of Cypress Hills has radii of , both respectively for Manhattan- and Queens-bound trains. As with other BMT Eastern Division lines, the Jamaica Line can only accommodate trains with eight or eight cars. Due to the narrow turning radiuses of the lines, cars (R44, R46, R68, R68A) could not be used on the Eastern Division. ==History==

The Union Elevated Railroad, leased to the Brooklyn Elevated Railroad, opened an elevated line above Broadway from Gates Avenue northwest to Driggs Avenue in Williamsburg on June 25, 1888. This was a branch of the existing Lexington Avenue Elevated, which then ended at Van Siclen Avenue; Broadway trains ran between Driggs and Van Siclen Avenues. A popular free transfer was available at Gates Avenue to Lexington Avenue trains towards Downtown Brooklyn. The Broadway Elevated was extended to Broadway Ferry on July 14, 1888. An extension of the Broadway Elevated east to Cypress Hills, over Fulton Street and Crescent Street, opened on May 30, 1893, On May 30, 1903, a connection between the Broadway Elevated and trolley tracks was completed south of the Cypress Hills terminal. Known as the Cypress Hills Incline, it allowed trains to run to 168th Street in Jamaica via Jamaica Avenue. This service was discontinued on December 30, 1903, due to traffic congestion in Jamaica. A connection to the Williamsburg Bridge was established in 1908, rendering the two westernmost stations on the Broadway Ferry Branch obsolete. These two stations were closed on July 3, 1916. The eastern extension along Jamaica Avenue to 168th Street was opened on July 3, 1918. Joint service with the Long Island Rail Road's Atlantic Branch existed between Norwood Avenue and Crescent Street stations with a connection built at Chestnut Street in Brooklyn. This allowed BRT trains to access the Rockaways and Manhattan Beach, while affording the LIRR a connection into Manhattan to the BRT terminal located at Park Row over the Brooklyn Bridge (this service predated the opening of the East River Tunnels to Penn Station). This service ended in 1917 when the United States Railroad Administration took over the LIRR, and classified different operating standards between rapid transit trains and regular heavy rail railroads such as the LIRR. In Fiscal Year 1930, the platforms at Kosciuszko Street were lengthened to accommodate an eight-car train of Standard subway cars. By the time the Independent Subway System extended the Queens Boulevard Line along Hillside Avenue in Jamaica in 1937, residents became dissatisfied with the Jamaica Elevated. Construction of the Archer Avenue subway lines began in 1973. However, the city was hit by a major financial crisis during the mid-1970s delaying the completion and opening of the new line. Regardless of these circumstances and despite opposition from some area residents, the three easternmost stations (Sutphin Boulevard, 160th Street, and 168th Street) were closed on September 10, 1977, with most of that segment of the line being demolished by 1979. The two other stations west of that point (Metropolitan Avenue and Queens Boulevard) were closed in 1985, with the line there being demolished in 1990. The Archer Avenue subway was opened in 1988. Two remnants of the former Jamaica El in Jamaica itself still exist today: the 144th Place power substation, which is now used for the Archer Avenue subway, and the station house and tower for 168th Street, which can be found on the southeast corner of Jamaica Avenue and 165th Street and is now used as a Boston Market restaurant. In 1986, the New York City Transit Authority launched a study to determine whether to close 79 stations on 11 routes, including the segment of the Jamaica Line east of Crescent Street, due to low ridership and high repair costs. Numerous figures, including New York City Council member Carol Greitzer, criticized the plans. Eastern Jamaica Line third track proposals On July 7, 1934, the Transit Commission ordered that the BMT construct a transformer in Woodhaven at 77th Street, which would provide more power, and therefore it would allow the construction of a third track on the Jamaica El. In 1958, the New York City Transit Authority first proposed the installation of a third track on the Jamaica El to provide peak-direction express service. The 1958 plan would have eliminated two tight right-angle curves of the Crescent Street "S-curve" between the Jamaica Avenue and Fulton Street portions of the route, by building a new elevated structure that would run diagonally from 80th Street to about Grant or Nichols Avenues, just east of Crescent Street. A 50- to 75-foot-wide right-of-way would have been needed, and since the line would have cut diagonally across several streets, 75 homes were slated to be torn down. Since the new elevated structure would take a more direct route, some local stations would be eliminated. The stops at Cypress Hills and Elderts Lane would have been eliminated, and a new stop replacing them would have been built around 75th Street and either Rockaway Boulevard or 91st Avenue. As part of the 1959 capital budget of the Transit Authority, $25.25 million was allocated for the construction of a third track on the Jamaica Elevated from 160th Street to Alabama Avenue. The stations from Alabama Avenue to and including Crescent Street are: Alabama Avenue, Van Siclen Avenue, Cleveland Street, Norwood Avenue and Crescent Street. All of these stations have center island platforms; to allow for the construction of a third track, the current platforms would have been demolished and replaced with side platforms. The Alabama Avenue and Van Siclen Avenue stops would be replaced by one stop in between the two stations to allow for better spacing, , between stations. The Cleveland Street station would have been replaced with a new station west of the existing station. The Norwood Avenue and Crescent Street stations would have been replaced by a single station between the two stations. One alternative that would not have required the demolition of homes would have entailed replacing the elevated structure between Eastern Parkway and Cypress Hills with a new structure above Jamaica Avenue, with new stops built. , the only station on the Jamaica Line east of Broadway Junction with three tracks On October 9, 1958, because of a lack of funds and because of community opposition, the City Planning Commission removed the project from the capital outlay budget. On July 14, 1959, the third-track project was put into the New York City Transit Authority's 1960 budget. On August 18, 1959, the New York City Transit Authority through an appeal made by the Authority's chairman, Patterson, tried to obtain approval from the City Planning Commission for a $27 million project to construct a third track on the BMT Jamaica Line. The installation of the third track would have attracted passengers from the overcrowded IND Queens Boulevard Line, as there would be significant time savings between 168th Street and Marcy Avenue. The Planning Commission killed the plan in the prior year, because of insufficient evidence that there was a need for such a project. On June 18, 1959, skip-stop service was implemented on the Jamaica El, with trains stopping at alternate stations between 168th Street and Eastern Parkway with the hope of enticing riders from the IND Queens Boulevard Line to use the new skip-stop service. If skip-stop service was a success, the Transit Authority would have shelved the triple-tracking project. The project, as it was planned in 1962, would have necessitated the condemnation of about 200 homes and would have cost $35 million. The only express stop between 168th Street and Eastern Parkway would have been Woodhaven Boulevard, which would have needed to be reconstructed to allow for express platforms to be built. In November 1967, William Ronan, chairman of the Metropolitan Commuter Transportation Authority, and later the chairman of the Metropolitan Transportation Authority, suggested that money from a transportation bond issue could have paid for the installment of the third track on the line. ==Service patterns==

The following services use part or all of the BMT Jamaica Line: The line has had two major service patterns: the 14 Broadway (Brooklyn) Line (earlier called the Canarsie Line, before that line was connected to the 14th Street Line) and the 15 Jamaica Line. Eventually, the 14 became the KK (which became the K in 1974) and the 15 the J; the K was eliminated in 1976. The Z was introduced in 1988 to provide skip-stop service with the J, using the same pattern that the 14/K and 15/J formerly used in multiple instances throughout their history. ==Nomenclature==

From its acquisition by the BRT to city ownership in 1940, the portion of the line from its western terminus to Cypress Hills was known as the Broadway El or the Broadway Line. Past 1940, the line was known as the Broadway (Brooklyn) Line to distinguish from the underground Broadway Line in Manhattan. Beyond that point it was known as the Jamaica Avenue El or the Jamaica Line. Subsequent to city takeover, the dividing line between the Broadway and Jamaica Avenue Lines was often considered to be the more westerly station at Eastern Parkway, now known as Broadway Junction. ==Station listing==
