Before the Chrystie Street Connection The Jamaica Line – then known as the Broadway Elevated – was one of the original elevated lines in Brooklyn, completed in 1893 from
Cypress Hills west to
Broadway Ferry in
Williamsburg. It was then a two-track line, with a single local service between the two ends, and a second east of
Gates Avenue, where the
Lexington Avenue Elevated merged. This second service later became the
12, and was eliminated on October 13, 1950, with the abandonment of the Lexington Avenue Elevated. The second major service on the Broadway Elevated ran between
Canarsie and Williamsburg via the
BMT Canarsie Line, started on July 30, 1906, when the Broadway and Canarsie tracks were connected at East New York. As part of the
Dual Contracts, an extension from Cypress Hills east to
Jamaica was completed on July 3, 1918, a third track was added west of East New York, and express trains began running on it in 1922. The
Brooklyn–Manhattan Transit Corporation numbered its services in 1924, and the Canarsie and Jamaica services became 14 and 15. Both ran express during rush hours in the peak direction west of East New York. Express trains would only stop at Myrtle Avenue, Essex Street and Canal Street, before making local stops afterwards. Additional 14 trains, between
Eastern Parkway or
Atlantic Avenue on the Canarsie Line and Manhattan provided rush-hour local service on Broadway. When the
14th Street–Eastern Line and Canarsie Line were connected on July 14, 1928, the old
Canarsie Line service was renamed the
Broadway (Brooklyn) Line, providing only weekday local service over the Broadway Elevated west of Eastern Parkway. The Atlantic Avenue trips remained, and rush-hour trains continued to serve
Rockaway Parkway (Canarsie), though they did not use the Broadway express tracks. The 14 was later cut back to only rush-hour service. On the Manhattan end, the first extension was made on September 16, 1908, when the
Williamsburg Bridge subway tracks opened. Broadway and Canarsie trains were extended to the new
Essex Street terminal, and further to
Chambers Street when the line was extended on August 4, 1913. When the
BMT Nassau Street Line was completed on May 30, 1931, the 15 was extended to
Broad Street, and the 14 was truncated to
Canal Street. Some 14 trains began terminating at
Crescent Street on the Jamaica Line in 1956. Manhattan-bound rush hour
skip-stop service between Jamaica and East New York was implemented on June 18, 1959, with trains leaving 168th Street on weekdays between 7 a.m. and 8:30 a.m. Express 15 trains served "A" stations, while the morning 14 became the
Jamaica Local, running between Jamaica and Canal Street, and stopped at stations marked "B". Express 15 trains continued to run express between Eastern Parkway and Canal Street, making only stops at Myrtle Avenue, Essex Street, and Canal Street. • All trains:

Chrystie Street Connection to 1977 When the
Chrystie Street Connection opened on November 26, 1967, many services were changed. The two local services – the #15 (non-rush hour Jamaica local) and #14 (rush hour Broadway-Brooklyn local) – continued as the JJ without any major routing changes. Thus non-rush hour JJ trains ran between Jamaica and Broad Street, while morning rush hour JJ trains ran to Canal Street, and afternoon rush hour JJ trains ran between Canal Street and Atlantic Avenue or Crescent Street. The rush-hour express J was combined with the weekday
Brighton Local via tunnel to form the weekday QJ, running between Jamaica and
Brighton Beach via the Jamaica Line (express during rush hours in the peak direction),
BMT Nassau Street Line,
Montague Street Tunnel, and
BMT Brighton Line (local). Finally, the was a special peak-direction rush-hour service, running local on the Jamaica Line in the AM, express in the PM, Nassau Street Line, Montague Street Tunnel, and
BMT Fourth Avenue Line to
95th Street in
Fort Hamilton. This service served two purposes: (1) early AM service from Jamaica prior to the first QJ trains got the equipment to 95th Street in Brooklyn in time for the AM rush, and obviated the need to have early service to Brighton Beach; and (2) in the evening, trains returned from 95th Street in Brooklyn to Jamaica, allowing the QJ to avoid having to run on the Brighton Line in the Manhattan direction post-rush hour. The next change was made on July 1, 1968, when the Chrystie Street Connection tracks to the Williamsburg Bridge opened. A new service, KK, was instituted that provided skip-stop service from 168th Street/Jamaica along with the QJ in both AM and PM rush hours; because of the limited skip-stop time spans, other terminals for the KK included Rockaway Parkway, Atlantic Avenue, Eastern Parkway and 111th Street. The KK provided service to 57th Street/6th Avenue, as the B served 168th Street-Washington Heights during rush hours; during non-rush hours, the B began serving 57th Street/6th Avenue. The MM (depicted with a dark green bullet on
R27 signage) had been proposed as a supplement to the KK as a local to 57th Street–Sixth Avenue, but was kept as the M and extended from Chambers Street to Broad Street. The was eliminated, being cut north of
Chambers Street and relabeled as an
RR variant, and the off-hour JJ was relabeled QJ. Less than two months later, on August 18, the QJ was extended to
Coney Island–Stillwell Avenue, and the D cut back to Brighton Beach during QJ operating hours in order to avoid switching delays at Brighton Beach. On July 14, 1969, afternoon skip-stop service on the KK and QJ was discontinued due to rider complaints. On January 2, 1973, the QJ, which was the longest route in the transit system, was cut back to Broad Street and redesignated the J; and the was extended to Coney Island in its place. At the same time, the KK was cut back to Eastern Parkway from 168th Street and renamed the K, and both skip-stop patterns were carried out by alternate J trains between 7:25 a.m. and 8:12 a.m.. J trains making A stops trains stopped at 168th Street, Sutphin Boulevard, Metropolitan Avenue, 111th Street, Woodhaven Boulevard, Elderts Lane, Cypress Hills, Norwood Avenue, Van Siclen Avenue, and Eastern Parkway, while trains making B stops stopped at 168th Street, 160th Street, Queens Boulevard, 121st Street, 102nd Street, Forest Parkway, Elderts Lane, Crescent Street, Cleveland Street, and Eastern Parkway. All J trains would run express between Eastern Parkway and Essex Street between 6:00 a.m. and 9:05 a.m. from 168th Street, and from 3:35 p.m. to 7:00 p.m. leaving Essex Street. The K was discontinued entirely on August 30, 1976, eliminating the J skip-stop and express service east of
Myrtle Avenue in the evening rush hour. Skip-stop service was retained toward Manhattan during the morning rush hour. One-way express service remained west of Myrtle Avenue, for the M was switched to the local tracks at that time. On January 24, 1977, as part of a series of NYCTA service cuts to save $13 million, many subway lines began running shorter trains during middays. As part of the change, J trains began running with four cars between 9:15 a.m. and 1:15 p.m. On May 2, 1977, J trains began running in skip-stop service between Eastern Parkway and Myrtle Avenue. Chauncey Street and Gates Avenue were designated as A stops, while Halsey Street and Kosciusko Street were designated as B stops. and to
121st Street on April 15, 1985, as portions of the elevated Jamaica Line closed and were demolished. The Q49 shuttle bus replaced service at the closed stations until 1988. On December 1, 1980, AM rush hour skip-stop service was discontinued. The
BMT Archer Avenue Line was scheduled to open on December 11, 1988, extending the J east from 121st Street to
Jamaica Center–Parsons/Archer. The Z designation, along with the present J/Z skip-stop service pattern, would be introduced the following day; skip-stop service operated between
Sutphin Boulevard and
Myrtle Avenue during weekday rush hours; in addition, both lines made express stops between Myrtle Avenue in Brooklyn and Canal Street in Manhattan, stopping at
Marcy Avenue and
Essex Street. All service terminated at Broad Street in Manhattan. Bus service on several Queens bus routes was rerouted to serve Jamaica Center instead of the
169th Street station several blocks away. The J/Z skip-stop service was touted, in an attempt to relieve some crowding on the
IND Queens Boulevard Line, as being faster to
lower Manhattan than E, F, and R service. Because the MTA hoped that Queens passengers would use the J/Z instead of the E, F, and R, every subway car on the J and Zs fleet was completely
graffiti-free. The first J train along the Archer Avenue Line operated on December 10, arriving at Jamaica Center at 11:42 PM and departing the station at 11:53 PM. One of the goals of the Archer Avenue project was to make Jamaica Line service as attractive as possible, and as a result the TA planned to provide a form of express service. The two options considered to speed up Jamaica Line service were
skip-stop service, which would have split Jamaica services into two patterns that served alternate stops, and a zone-express service, which would have split Jamaica services into a
short-turn local service and a full-length express services. The zone-express option was dismissed in favor of the skip-stop option because its operation has to be very precisely timed so as to not hinder reliability, because service in the outer zone past the boundary of zone express service at
Crescent Street or 111th Street would be too infrequent, and because many stations would lose half their service. Outer-zone expresses, after Crescent Street would skip stops on the local track until Eastern Parkway, from where it would run on the express track, stopping at Myrtle Avenue before going straight to Essex Street in Manhattan, skipping Marcy Avenue. Outer-zone expresses and inner-zone locals would have each been limited to frequencies of 10 minutes. To further speed up service, J and Z trains would skip Flushing Avenue, Lorimer Street and Hewes Street. Skip-stop service ran to Manhattan in the morning between 7:15 and 8:15 a.m. and to Jamaica between 4:45 and 5:45 p.m. Weekday midday express service was added with J service continuing to run express in the peak direction between Marcy and Myrtle. Surveys of ridership at local stops found that service could be adequately provided by midday M service. It was expected that 2,250 Queens Boulevard riders would switch to the J and Z. Express service was not implemented between Broadway Junction and Myrtle Avenue because local service would have needed to be operated between those points in addition to the J and Z. The two terminals for such a service (
57th Street and
Broad Street) lacked spare capacity, although it was acknowledged that 57th Street on the
IND Sixth Avenue Line could be used as a terminal once
Manhattan Bridge subway-track repairs were completed.
Post-1990 changes On September 30, 1990, weekend J service was cut back from Broad Street to
Canal Street, but it was extended back to
Chambers Street in January 1994. From May 1 to September 1, 1999, the
Williamsburg Bridge was closed for reconstruction. J trains ran only between Jamaica Center and Myrtle Avenue; Z trains and skip-stop service operated in both directions between Jamaica Center and Eastern Parkway-Broadway Junction. During the closure, B39 bus service over the Williamsburg Bridge was free. The closure was anticipated to last until October 1999, but regular subway service was restored one month ahead of schedule. The project cost $130 million, including replacing the tracks support structure, signal system and other equipment. On September 1, J trains began stopping at the
Bowery station 24 hours. J trains previously skipped Bowery between 6 AM and 8 PM on weekdays when the M was operating into Manhattan. The Z also began stopping at Bowery during its hours of operation for the first time ever on this day. After the
September 11, 2001 attacks, the Z and skip-stop services were suspended, and the J was initially cut back from Broad Street to Broadway Junction, but service got restored to as far as Essex Street on the evening of September 12 and made all stops along the route. On September 17, J trains were extended beyond Broad Street via the
Montague Street Tunnel during daytime hours and originated and terminated at
Bay Ridge–95th Street to replace the R, which got suspended; trains made all stops along the full route. Overnight service was split into two sections, with the northern section operating between Jamaica Center and either Broad Street or Chambers Street, and the southern section operating as a shuttle between
36th and 95th Streets. Normal J service was restored on October 28; the Z and skip-stop services were restored on the following day. On November 20, 2008, in light of severe budget woes, the MTA announced a slew of potential service cuts; among them was the potential elimination of the Z and skip-stop services. The J would make all stops between Sutphin Boulevard and Myrtle Avenue; weekday peak direction express service between Myrtle and Marcy Avenues would be retained. In May 2009, after the
New York State Legislature passed legislation to offer financial support to the MTA, this planned service cut was taken off the table. However, on December 8, 2009, the MTA announced that a budget shortfall would once again result in service cuts, among them being the discontinuation of the Z and skip-stop services; the proposal to discontinue the Z and skip-stop services were withdrawn in March 2010, but other service cuts that the MTA proposed still took place in June of that year. J and Z trains and skip-stop service was altered after
Hurricane Sandy disrupted service around the transit system in 2012. J service was suspended entirely on the evening of October 28, but was restored on the morning of October 31; the Z and skip stop services remained suspended, and the J was initially cut back from Broad Street to Hewes Street and made all stops along the route. Service was restored to as far as Essex Street on November 3. The Z and skip-stop services resumed on November 19, with both J and Z trains originating and terminating at Chambers Street instead of Broad Street; service to Broad Street was restored on December 4. In May 2014, all trains began stopping at
Alabama Avenue, presumably for the convenience of transit employees who work at the nearby East New York Yard and
East New York Bus Depot. In July 2014, the MTA proposed that weekend J service be extended from Chambers Street to
Broad Street. The service change went into effect on June 14, 2015. From June 26, 2017 to April 27, 2018, J and Z trains ran local between Broadway Junction and Marcy Avenue at all times, supplementing the M, due to the
BMT Myrtle Avenue Line connection being closed for reconstruction. In March 2020, Z trains and skip-stop service was temporarily suspended due to lack of ridership and train crew availability caused by the
COVID-19 pandemic. Full service was restored in June 2020. From December 29, 2021, to January 19, 2022, Z trains and skip-stop service was again suspended due to a shortage of crew members exacerbated by the COVID-19 pandemic. On July 1, 2022, J service was cut back to
121st Street, and Z trains and skip-stop service were suspended due to track replacement on the lower levels of the
Jamaica Center and
Sutphin Boulevard stations. Z train and J/Z skip-stop service was restored on September 19, 2022. On February 26, 2023, Jamaica Center-bound J and Z trains skipped 75th Street-Elderts Lane and Woodhaven Boulevard until January 2024 as part of a four-phase station renovation project for both stations, as well as accessibility improvements and elevator installation for the latter. The second phase closed the Manhattan-bound platforms for both stops from early 2024 to mid-2024. Phase 3 closed down the Jamaica Center-bound platforms at Cypress Hills on July 22, 2024, and at 85th Street–Forest Parkway on August 12, 2024, for renovations until early 2025. Phase 4 closed the Manhattan-bound platforms down until July 21st, 2025. During those phases, J and Z trains would still operate skip-stop service between Myrtle Avenue-Broadway and Crescent Street, Brooklyn, but with both trains making all local stops to/from Sutphin Boulevard-Archer Avenue-JFK Airport, Queens, except for the affected stops. Weekend frequencies on the J route were increased in July 2023. From June 28 to September 3, 2024, to accommodate riders displaced by the suspension of the for signal modernization taking place on that route, peak-direction express service on the J and Z was suspended between Myrtle and Marcy Avenues, with both routes making all stops along this segment. == Route ==
