M (New York City Subway service)

History

M service

1914–1960

Until 1914, the only service on the Myrtle Avenue Line east of Grand Avenue was a local service between Park Row (via the Brooklyn Bridge) and Middle Village (numbered 11 in 1924). The Myrtle Viaduct, a two-track ramp connecting the Myrtle Avenue Line with the BMT Broadway Elevated (now the Jamaica) Line at the Myrtle Avenue station was opened on July 29, 1914, allowing for a second service, the daytime Myrtle Avenue–Chambers Street Line, or Myrtle-Chambers Line, which ran along the Broadway elevated and the Williamsburg Bridge to Chambers Street on the Nassau Street Loop in Lower Manhattan.

Following the completion of a third track along the Broadway Elevated between Marcy Avenue and Myrtle Avenue on January 17, 1916, these trains began running express on the Broadway Elevated during the evening rush hour in the peak-direction. By 1920, trains later began running express in the morning rush hour and on Saturday afternoon in the peak direction. The number 10 was assigned to the service in 1924. At the time, service ran on weekdays between 6 a.m. and 8 p.m., on Saturdays from 6 a.m. and 9 p.m., and on Sundays from 12:30 to 11 p.m. In the morning rush hour, trains ran express between Central Avenue and Essex Street, and during the evening rush hour, trains ran express between Bowery and Broadway–Myrtle Avenue.

Sunday service was removed in June 1933. All Saturday trains began running local on June 28, 1952. On February 10, 1958, the four rush hour Brighton-Nassau special trains began stopping at Neck Road and Avenue U. In addition, the evening rush hour trains began stopping at DeKalb Avenue, as had been done by morning rush hour trains. On June 28, 1958, Saturday service was discontinued. On May 26, 1959, midday service was eliminated, making the Myrtle-Chambers Line rush-hours only. Service had previously operated on weekdays from 6 a.m. to 8 p.m. Beginning on February 23, 1960, express trains began stopping at Marcy Avenue, which was originally a local stop.

1961–1978

In 1961, with the arrival of new R27s which featured rollsigns with new lettered designations for the BMT's numbered services, the 10 was renamed the M. Since these cars were not assigned to the route, it remained signed as 10. However, the rush hour Nassau Street specials on the BMT Brighton Line and BMT Fourth Avenue Line were signed using the M designation. The line was officially designated "M" after the Chrystie Street changeover on November 27, 1967.

The second half of the Chrystie Street Connection opened on July 1, 1968, and the , which had run along Nassau Street to Broad Street, was relocated through the new connection to the IND Sixth Avenue Line (and renamed the KK). To augment service to Broad Street, the M was extended two stations, from Chambers Street to Broad Street.

On October 4, 1969, the Myrtle Avenue Elevated was discontinued south of Myrtle Avenue to Jay Street. To make up for the loss of MJ service, M service was expanded to run during middays, operating weekdays between 6 a.m. and 7 p.m., and a new SS shuttle began running between Myrtle Avenue and Metropolitan Avenue at other times. In August 1972, the off-hour SS shuttle was renamed as part of the M.

Effective January 2, 1973, the daytime QJ was truncated to Broad Street as the , and the M was extended beyond Broad Street during the day along the 's former route to Coney Island–Stillwell Avenue, via the Montague Street Tunnel and Brighton Line local tracks. With the extension of the M onto the Brighton Line, there were also changes to D service. Northbound weekday M train service originating at Kings Highway would begin at 5:46 a.m., while northbound service from Coney Island would begin at 6:34 a.m. From 5:40 to 6:34 a.m. northbound D trains would run local from Brighton Beach to Kings Highway, and then run express to Prospect Park. Late morning and early afternoon D trains would from then on run express from Brighton Beach to Kings Highway. The span of D express service to Brighton Beach was extended by 45 minutes to 9:05 p.m. from Prospect Park, and the span of M service from Broad Street to Coney Island was extended by 45 minutes from the previous span of QJ service to cover local stops. Two M trains began service at Brighton Beach in the morning rush hour, and in the early morning, three M trains entered service at Brighton Beach, and six entered service at Kings Highway. In addition, the final nine southbound M trains of the evening terminated at Brighton Beach. On May 13, 1974, two of the three northbound early morning trains that were placed into service at Brighton Beach were moved to enter service at Kings Highway.

The local K (renamed from KK in 1973) was eliminated on August 27, 1976, and M express service between Myrtle Avenue and Marcy Avenue ended.

On December 3, 1979, four northbound weekday morning rush hour trains that had been put into service at Kings Highway began service at Brighton Beach.

1986–2004

M service along Fourth Avenue, operating between 6:30 a.m. and 8:00 p.m., was switched to the local tracks on May 31, 1994, switching with the , which had run local since the M was moved in 1987. The change was implemented on a six-month trial, and was made permanent afterwards. This change was made as part of New York City Transit's Fare Deal, which sought to increase transit ridership by improving service. The change was proposed in November 1993, and public hearings on the change were held. The change reduced travel times by minutes for 26,000 people, a majority of the riders on the corridor. As a result of the change, some riders shifted from using stations on the BMT West End Line to the BMT Sea Beach Line, and from Fourth Avenue local stops to Fourth Avenue express stops.*

• Market research found that 44% of M riders felt that crowding decreased, that 35% of M and 30% of N riders used their service more frequently, that 58% of riders thought the change was a good idea, and that only riders at the 45th Street and 53rd Street stations, which received less frequent service, viewed the changes negatively. This change increased operating costs by $245,000.*

The midday M (between 9:30 a.m. and 3:30 p.m.) was temporarily truncated to Chambers Street on April 30, 1995, from Ninth Avenue in Brooklyn due to the closure of the Manhattan Bridge during weekday middays for structural repairs.*

• The change was made to provide capacity in the Montague Street Tunnel for the Q, which was rerouted from the Manhattan Bridge. To replace M local service in Brooklyn, midday N trains began making local stops in Brooklyn. In addition, the span of M service to Brooklyn was reduced by fifteen minutes in the early morning and in the late evening by 25 minutes.*

The elimination of midday service to Brooklyn was made permanent on November 12, 1995, after the six-month repair project was completed, as part of a series of service cuts made by New York City Transit to make up a shortfall in its budget. It had been expecting a $160 million surplus in 1995, but due to reductions in state and federal contributions, it was left with a deficit which could reach $172 million. The elimination of midday M service to Brooklyn was part of a larger plan to reduce spending in order to avert a fare increase, which Governor George Pataki and Mayor Rudy Giuliani had pressured the MTA to avoid. Only 4,200 riders used M service to Brooklyn during middays, with fewer than 20 passengers per car, or 80 passengers per train (the M used four-car trains during middays). Because of the low cost effectiveness of operating service to Brooklyn and because of the existence of alternate service on the N and R, it was decided to cut the service. This service cut saved $664,000 annually. Three alternative operating plans were considered: maintaining existing midday service, terminating midday service at Broad Street, and operating service as a shuttle like weekend and late night service. It was decided not to terminate service at Broad Street because it negated a large portion of the crew savings due to the need for personnel to relay trains at the Broad Street terminal, longer running times, and because it had the potential to delay J service, which already terminated there. The shuttle option was dismissed because it would inconvenience a far larger number of M riders.*

• Truncation of midday M service was proposed as early as January 1991 for an October implementation of that year, subject to approval from the MTA board.

From July 23, 2001, to February 22, 2004, the closure of the north tracks on the Manhattan Bridge resulted in a midday extension back to Ninth Avenue, as well as an extension of the times that the rush hour service was provided to 10 p.m. This change preserved service between the West End Line and Chinatown for passengers that would have taken the to Grand Street. When full Manhattan Bridge service was restored, midday M service was cut back to Chambers Street and replaced in south Brooklyn by the . Neighborhood leaders in Chinatown were angered by the decision to terminate midday at Ninth Avenue, instead of running it to Bay Parkway. A spokesman for New York City Transit stated that it was easier to terminate trains at Ninth Avenue and that a signal upgrade project was going on further down the line. In addition, the temporary midday service to Brooklyn was lightly used, with an average of 50 to 60 riders per train during middays going to Brooklyn, and fewer than 50 riders per train during evenings going to Brooklyn.

After the September 11, 2001 attacks, M service initially operated as a shuttle between Metropolitan Avenue and Myrtle Avenue–Broadway. On September 17, M service was rerouted via the Sea Beach Line and originated and terminated at Stillwell Avenue to replace the , which got suspended; service via the West End Line continued to be provided by trains. M trains made all stops along the reroute. Normal M service was restored on October 28.

2007–2010

In December 2007, the MTA announced that it planned to set aside $27 million in 2008 and $60 million annually afterwards for service enhancements to help riders deal with increased fares. Extended weekday evening M service to Broad Street and weekend service to Chambers Street were part of the plan. However, on March 24, 2008, it was announced that because the agency received substantially less revenue from taxes on real estate transactions, the enhancements were reduced to $4.5 million in 2008 and $8.9 million annually afterwards. The plan to extend weekend service to Chambers Street was dropped. After several months' delay, weekday evening trains were extended to Broad Street on July 27, 2008.[[File:Marty Markowitz, Daniel Squadron, Michael Burke, Paul Nelson.jpg|left|thumb|Brooklyn politicians eulogize the "death" of the Nassau Street Line M]] 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 rush-hour M service which had extended beyond Chambers Street on the Nassau Street Line in Lower Manhattan to Bay Parkway on the West End Line in Brooklyn. In May 2009, after the New York State Legislature passed legislation to offer financial support to the MTA, the service cut was taken off the table. However, in late 2009, the MTA once again discovered that it was confronting another financial crisis; most of the same service cuts threatened just months earlier were revisited. One proposal included completely phasing out M service and using the as its replacement. Under this proposal, the V would no longer serve its southern terminus at Second Avenue. Instead, after leaving Broadway–Lafayette Street, it would run along the Chrystie Street–Williamsburg Bridge connection, unused since the elimination of the K in 1976, and stop at the upper (BMT) level of Essex Street in Manhattan before serving all M stations to Metropolitan Avenue in Queens.

The MTA determined that this move, while still a service cut, would actually benefit M riders in northern Brooklyn; approximately 17,000 weekday riders used that route to reach its stations in Lower Manhattan, whereas 22,000 transferred to other routes to reach destinations in Midtown Manhattan. However, only about 10,000 riders in Southern Brooklyn used the M to access the Nassau Street Line. This merger opened up new travel options for northern Brooklyn and Queens in that it allowed direct and more convenient access to areas that were not previously served by those routes such as Midtown Manhattan, as before the service changes, M train passengers had to transfer at least once if heading to Midtown.

On March 19, 2010, it was reported that the plan had been changed and that the new combined service would instead carry the M train designation, recolored orange to designate the IND Sixth Avenue Line as its Manhattan trunk line, while discontinuing the V train. Many MTA board members opposed the elimination of the M designation, saying that riders would be more comfortable with that rather than a V designation, and because the M had been around longer than the V. The last M trains to Bay Parkway ran on June 25, 2010, and M service via the Chrystie Street Connection began the following Monday, June 28, 2010.

2011–present

On June 8, 2014, weekend daytime M service was extended to Essex Street as part of an $18 million funding project to improve subway service, as well as to offer a direct connection to the F train on Saturdays and Sundays. Late night service continues to terminate at Myrtle Avenue.

During the morning rush hour, the M is at 90 percent of the New York City Subway's capacity guidelines. Ridership on the M has been growing very rapidly since the 2010 service change, and this trend is expected to continue. In June 2016, the frequencies of service on the M route during peak hours were increased, with the expectation that peak train frequencies would be raised again in the future.

From July 1, 2017, to April 30, 2018, reconstruction of two sections of the BMT Myrtle Avenue Line—the approaches to the line's junction with the BMT Jamaica Line and Fresh Pond Bridge over the Long Island Rail Road's Montauk Branch in Queens—required a reroute of M service. Trains to and from Manhattan and Queens, instead of diverging at Myrtle Avenue to go to Metropolitan Avenue, continued east on the BMT Jamaica Line and terminated at Broadway Junction at all times except late nights, when service was suspended. A limited amount of rush hour trains ran between 71st Avenue in Queens and Second Avenue in Manhattan, replicating the train's routing prior to its discontinuation in 2010. Three shuttle bus routes ran during reconstruction of the Fresh Pond Bridge: one between Myrtle Avenue and Fresh Pond Road; the second between Myrtle and Metropolitan Avenues, skipping the Fresh Pond Road station during the daytime hours; and the third between Flushing Avenue/Broadway and Middle Village–Metropolitan Avenue, stopping at Flushing and Wyckoff Avenues for a transfer to the BMT Canarsie Line at Jefferson Street.

When the Fresh Pond Bridge project was completed on September 2, 2017, two six-car shuttle trains began operating between Metropolitan and Wyckoff Avenues at all times, running separately from each other on each of the two tracks; two additional six-car trains were stored in the Fresh Pond Yard in order to swap consists in and out of service. These shuttles, along with a shuttle bus route that provided service between Wyckoff Avenue and Broadway, ran until April 27, 2018.

When the 14th Street Tunnel shutdown started in April 2019, weekend and weekday evening M service (from 11:00 p.m. to 1:15 a.m.) was extended from Essex Street to 96th Street on the Second Avenue Subway in Manhattan, via 63rd Street, to compensate for limited L service between Brooklyn and Manhattan. The M had to run to 96th Street because of capacity reductions on the Queens Boulevard Line due to ongoing weekend construction. Both weekday and weekend M frequencies were also increased. This extra service was discontinued after completion of tunnel construction on April 27, 2020. Weekday evening service after 9:15 p.m. was also indefinitely cut back from Forest Hills to Essex Street to accommodate maintenance work for the installation of communications-based train control on the Queens Boulevard Line, Eighth Avenue Line, and Sixth Avenue Line.

Weekend frequencies on the M route were increased in July 2023. Starting August 28, 2023, weekday M trains were truncated to 57th Street in Manhattan, and F trains were rerouted via the 53rd Street Tunnel between Queens and Manhattan, due to track replacement and other repairs in the 63rd Street Tunnel. Weekend M service continued to terminate at Essex Street. Service to Forest Hills resumed on April 1, 2024.

In June 2025, internal MTA documents were leaked, indicating that a proposal to reroute M trains through the 63rd Street Tunnel and reroute F trains through the 53rd Street Tunnel would be presented for approval. The route swap was anticipated to reduce overcrowding at 63rd Street line stations, as well as reduce reliance on interlockings west of the 36th Street station in Queens. In September 2025, the MTA confirmed that the F and M trains would swap routings on weekdays starting on December 8, 2025, with the F running via 53rd Street and the M running via 63rd Street. Service on the M route would also be increased during rush hours to provide additional service along the 63rd Street Line, since M trains ran less frequently than F trains.

MJ service

On March 5, 1944, 11 trains stopped running over the Brooklyn Bridge, instead ending at Bridge–Jay Streets on the Brooklyn side, and all 11 trains terminated there (with a free transfer to the IND trains at Jay Street–Borough Hall). In 1967, when the Chrystie Street Connection opened, the label MJ was assigned to the 11 service.

The western half of the Myrtle Avenue Line closed on October 4, 1969, ending MJ service, which was replaced with a free transfer to the B54 bus. Several days before the scheduled closing date, some supports for the elevated structure were hit by a truck, temporarily suspending service. Timber reinforcement was applied to damaged pillars, allowing service to resume until the scheduled closing date.
