The '''IRT Flushing Line''' is a [[rapid transit]] route of the [[New York City Subway|New York City Subway system]], named for its eastern terminal in [[Flushing, Queens]]. It is operated as part of the [[A Division (New York City Subway)|A Division]]. The [[Interborough Rapid Transit Company]] (IRT), a private operator, had constructed the section of the line from [[Flushing, Queens|Flushing]], [[Queens]], to [[Times Square]], [[Manhattan]] between 1915 and 1928. A [[7 Subway Extension|western extension]] was opened to [[Hudson Yards Redevelopment Project|Hudson Yards]] in western Manhattan in 2015, and the line now stretches from Flushing to [[Chelsea, Manhattan]]. It carries trains of the {{NYCS|7}} local service, as well as the express {{NYCS|7d|&lt;7&gt;}} during rush hours in the peak direction.<ref name="NYCS7">{{NYCS const|timetable|7}}</ref> It is the only currently operational IRT line to serve Queens.

It is shown in the color {{NYCS const|color|purple}} on station signs, the official subway map, and internal route maps in [[R188 (New York City Subway car)|R188]] cars. Before the line was opened all the way to Flushing in 1928, it was known as the '''Corona Line''' or '''Woodside and Corona Line'''. Prior to the discontinuation of [[Brooklyn–Manhattan Transit Corporation|BMT services]] in 1949, the portion of the IRT Flushing Line between [[Times Square (IRT Flushing Line)|Times Square]] and [[Queensboro Plaza (IRT Flushing Line)|Queensboro Plaza]] was known as the '''Queensboro Line'''. Since the mid-2010s, the line's signal system has been converted to an [[Signaling of the New York City Subway#Automation|automated system]].

The Flushing Line has various styles of architecture, which range from steel [[girder]] [[elevated railway|elevated structures]] to European-style concrete [[viaduct]]s. The underground stations have some unique designs as well. The designs include [[Hunters Point Avenue (IRT Flushing Line)|Hunters Point Avenue]], which is in an [[Italianate]] style; [[Grand Central–42nd Street (New York City Subway)|Grand Central–42nd Street]], which is a single round tube similar to a [[London Underground]] station; and [[34th Street–Hudson Yards station|34th Street–Hudson Yards]], which, with its deep vault and spacious interior, resembles a [[Washington Metro]] station.

The line has two distinct sections, split by the [[Queensboro Plaza (IRT Flushing Line)|Queensboro Plaza]] station. It begins as a three-track subway, with the center track used for express service, at [[Flushing–Main Street (IRT Flushing Line)|Flushing–Main Street]].<ref name="tracks">{{NYCS const|trackref|trackbook3}}</ref> It quickly leaves the ground onto a [[steel]] [[elevated railway|elevated structure]] above Roosevelt Avenue, passing [[Citi Field]] and the [[United States Tennis Association]]'s [[USTA National Tennis Center|National Tennis Center]]. A [[flying junction]] between [[Mets–Willets Point (IRT Flushing Line)|Mets–Willets Point]] and [[111th Street (IRT Flushing Line)|111th Street]] provides access to the [[Corona Yard]] from the local tracks.<ref name="trackbook">{{NYCS const|trackref|trackbook}}</ref> At 48th Street in [[Sunnyside, Queens|Sunnyside]], the line switches to [[Queens Boulevard]] and an ornate [[concrete viaduct]] begins. The express track ends between [[33rd Street–Rawson Street (IRT Flushing Line)|33rd Street–Rawson Street]] and Queensboro Plaza.<ref name="tracks" /><ref name=":2">{{Cite web|url=https://accessqueens.org/couch/uploads/file/4-5-16-askthemta_7train_presesentation.pdf|title=Flushing Line 2016 Town Hall April 5, 2016 Sunnyside, Queens|date=April 5, 2016|website=Access Queens|publisher=Metropolitan Transportation Authority|access-date=October 22, 2017}}</ref>

At Queensboro Plaza, the eastbound track ([[railroad directions|railroad north]]) is above the westbound track, with both tracks on the south side of the island platforms. On the north side of these platforms is the [[BMT Astoria Line]]. East of this point, both the Flushing Line and the Astoria Line were formerly operated by the [[Interborough Rapid Transit Company|IRT]] and the [[Brooklyn–Manhattan Transit Corporation|BMT]]. Connections still exist between the eastbound tracks just east of the platforms, but cannot be used for revenue service as BMT trains are wider than IRT trains. This is the only track connection between the Flushing Line and the rest of the subway system.<ref name="tracks" /><ref name=":2" />

West of Queensboro Plaza, the line sharply turns south onto an elevated structure over 23rd Street. It heads into the west end of [[Amtrak]]'s [[Sunnyside Yard]], and passes through two underground stations before entering [[Manhattan]] via the [[Steinway Tunnel]] under the [[East River]]. In Manhattan, the line runs under [[42nd Street (Manhattan)|42nd Street]], with part directly underneath the [[42nd Street Shuttle]] ({{NYCS trains|42nd}}), before angling towards 41st Street. The [[Times Square–42nd Street/Port Authority Bus Terminal (New York City Subway)|Times Square–42nd Street]] station, with no track connections to other lines, is directly under 41st Street.<ref name="tracks" />

West of Times Square, the tracks curve sharply downward before turning under [[11th Avenue (Manhattan)|11th Avenue]]. The tracks end at 24th Street, even though the last station is at [[34th Street–Hudson Yards (IRT Flushing Line)|34th Street]].<ref name="tracks" /><ref>{{NYCS const|trackref|469}}</ref> This segment was built as part of the [[7 Subway Extension|extension of the Flushing Line]] west to Manhattan's Far West Side (see {{section link||Extension westward}}).<ref name=NYTimes-Station-Opens-2015/> A decommissioned lower level at the [[IND Eighth Avenue Line]]'s [[42nd Street–Port Authority Bus Terminal]] station formerly blocked the way.<ref>{{Cite news |title=No Whoosh, No 'All Aboard' |first=Alex |last=Mindlin |url=https://www.nytimes.com/2008/04/20/nyregion/thecity/20port.html |newspaper=[[The New York Times]] |date=April 20, 2008 |access-date=February 28, 2010}}</ref> Although London ultimately received the bid for the [[2012 Summer Olympics]], New York City pursued the extension anyway, albeit as a means to enable the redevelopment of the far West Side under the [[Hudson Yards Redevelopment Project]].<ref name="olympic2012-won"/>

===Distinctions===
The Flushing Line is one of only two New York City non-[[S (New York City Subway service)|shuttle]] subway lines that hosts only a single service and does not share operating trackage with any other line or service; the other is the [[BMT Canarsie Line]], carrying the {{NYCS|L}} train. Because of this, the MTA is [[Signaling of the New York City Subway#Automation|automating the line]] with new trains using [[communication-based train control]] (CBTC), similar to the Canarsie Line (see {{Section link||Automation of the line}}).<ref name=page11/>

The IRT Flushing Line's 7 service has the distinction of running trains with the largest number of cars in the New York City Subway. 7 trains are eleven cars long; most other New York City Subway services run ten or eight-car trains. The trains are not the longest by total length, however. An IND/BMT train of ten {{convert|60|ft|adj=on}}-long cars or eight {{convert|75|ft|adj=on}}-long cars, which is {{convert|600|ft}} long, is still {{convert|35|ft|m}} longer than an IRT train of eleven {{convert|51.4|ft|adj=on}}-long cars, which is {{convert|565|ft}} long.<ref name="tracks" />

===Origins===
The earliest origins of the Flushing Line emerged on February 22, 1885, with the founding of the '''East River Tunnel Railroad'''. The railroad would construct the [[Steinway Tunnel]] under the East River, connecting the [[Long Island Rail Road]] in Queens with the [[New York Central Railroad]] in Manhattan.<ref>{{Cite news|url=https://timesmachine.nytimes.com/timesmachine/1885/02/22/103628293.pdf|archive-url=https://web.archive.org/web/20210819015807/https://timesmachine.nytimes.com/timesmachine/1885/02/22/103628293.pdf|url-status=dead|archive-date=August 19, 2021|title=Tunnel Under the East River.|date=February 22, 1885|work=The New York Times|access-date=January 9, 2018|language=en-US|issn=0362-4331}}</ref> However, the East River Tunnel Railroad Company went out of business. On July 22, 1887, [[Walter S. Gurnee]] and [[Malcolm W. Niven]] founded the New York and Long Island Railroad Company (NY&LIRR). They soon began planning for the tunnel.<ref name=":6" />

To run from West 42nd Street and Tenth Avenue to Van Alst Avenue after crossing under the East River, the builders planned for the remainder of the line to be constructed on private lands, and numerous alterations were made to the proposal.<ref name=":6" /> In 1890, [[William Steinway]] advised the company to utilize electricity to power the tunnels, believing that the construction of the tunnel would increase the value of his properties in the vicinity.<ref name=":6" /><ref>{{Cite news|url=https://timesmachine.nytimes.com/timesmachine/1890/12/28/106045783.pdf|archive-url=https://web.archive.org/web/20191222050527/https://timesmachine.nytimes.com/timesmachine/1890/12/28/106045783.pdf|archive-date=December 22, 2019|title=Rapid-Transit Systems; One Plan or Parts of Several May Be Adopted. the Availability and Utility of a Roomy Tunnel – Speed, Light, and Cleanliness Obtainable by the Use of Electricity.|date=December 28, 1890|work=The New York Times|access-date=January 9, 2018|language=en-US|issn=0362-4331}}</ref>

At Queensboro Plaza, the line met the BMT's [[60th Street Tunnel]], as well as a spur from the [[elevated (railway)|elevated]] [[IRT Second Avenue Line]] on the [[Queensboro Bridge]]. From this point east, the Flushing and Astoria Lines were built by the City of New York as part of the [[Dual Contracts]]. They were officially IRT lines on which the BMT held irrevocable and equal [[trackage rights]]. Because BMT trains were wider, and the platforms had been built for the IRT, normal BMT trains ran only to [[Queensboro Plaza (BMT Astoria Line)|Queensboro Plaza]], with a transfer to [[New York City Subway shuttles|shuttles]], using elevated cars, that alternated between the [[Astoria–Ditmars Boulevard (BMT Astoria Line)|Astoria–Ditmars Boulevard]] and Flushing–Main Street terminals.

In July 1920, the [[New York Public Service Commission|New York State Public Service Commission]] announced it would extend the Flushing Line two stops west to Times Square, with an intermediate station under Bryant Park. The western end of the Bryant Park station would be {{convert|300|ft}} east of Sixth Avenue, while the eastern end would be about {{convert|100|ft}} west of Fifth Avenue.<ref name=":12">{{Cite news |date=July 25, 1920 |title=Plan New Station for 42d Street; Proposed as Part of Extension of the Queensboro Subway. |language=en-US |work=The New York Times |url=https://www.nytimes.com/1920/07/25/archives/plan-new-station-for-42d-street-proposed-as-part-of-extension-of.html |access-date=July 12, 2022 |issn=0362-4331}}</ref><ref name="p576244392">{{cite news |date=July 25, 1920 |title=Subway Station on 42d St. Between 5th and 6th Avs. |page=A12 |work=New-York Tribune |id={{ProQuest|576244392}}}}</ref> The 42nd Street Association, a local civic group, regarded the station as very important.<ref name=":12" /> In May 1921, it was expected that contracts for the extension would be advertised shortly.<ref>{{Cite news |date=May 15, 1921 |title=East River Subway Nears Completion: Transit Commission Consulting Engineer Reports on Tube Construction |work=New York Herald |url=https://www.newspapers.com/clip/35604540/new-york-herald/ |access-date=July 12, 2022}}</ref>

On November 9, 1921, the New York State Transit Commission opened up the contract for the extension for bidding. The extension would take a slightly different route than the one specified in the Dual Contracts. The original proposal had the line constructed under 42nd Street to a point just to the east of Broadway, which would have forced riders transferring to the [[IRT Broadway–Seventh Avenue Line]] to walk a long distance.<ref name="Tribune1922">{{Cite news |date=November 6, 1922 |title=Queensboro Tube to be Extended West: Bids for Construction of Subway Over to 8th Ave. to be Opened Wednesday; Two Years' Job |work=New-York Tribune |url=https://www.newspapers.com/clip/65994240/new-york-tribune/ |access-date=July 12, 2022}}</ref>

The Times Square station would be designed at a lower level than the two existing stations at Times Square. It would have two upper mezzanines connected by passageways: a mezzanine east of Seventh Avenue extending to Broadway, and one west of Seventh Avenue. Escalators would connect these upper mezzanines with the lower mezzanine, and a provision would be made to permit the installation of an escalator to the east of Seventh Avenue. There would be two entrances at street level at each of the western corners of 41st Street and Broadway, and two entrances at the northeastern corner of 41st Street and Seventh Avenue.<ref name="Tribune1922" />

On November 22, 1921, the Powers-Kennedy Contracting Corporation was awarded a contract to construct the extension on a low bid of $3,867,138, below the estimated cost of over $4 million.<ref name="Tribune1922" /> This low bid was the narrowest margin ever recorded for any large city contract, beating out the next highest bidder by 0.7 percent. While the contractor was provided four years to complete work, engineers expected to reduce the time needed to do so to as little as three years. Since work on the project had to be completed underneath the foundations of several large buildings, such as theatres, and the north end of the New York Public Library, the contractor had to provide a $1 million bond.<ref>{{Cite news |date=November 28, 1921 |title=Subway Bids 0.7 P.C.

The project was expected to reduce crowding on the 42nd Street Shuttle by enabling riders to use the Queensboro Subway to directly access Times Square. 24,000 of the estimated 100,000 daily shuttle riders transferred to and from the Queensboro Subway. The line was to extend as far as Eighth Avenue to connect with the proposed [[IND Eighth Avenue Line]].<ref>{{Cite news |date=November 23, 1921 |title=Queensboro Subway Contract Is Awarded; $3,867,138 Bid for 42d Street Extension Let to Powers-Kennedy by Commission. |language=en-US |work=The New York Times |url=https://www.nytimes.com/1921/11/23/archives/queensboro-subway-contract-is-awarded-3867138-bid-for-42d-street.html |access-date=July 12, 2022 |issn=0362-4331}}</ref><ref name="p576494810">{{cite news |date=November 23, 1921 |title=Subway Power Expense Added To 'L' Burdens: Impoverished System Forced to Foot Bills for Overhead, According to Check-Up of Interborough Transactions Hedley on Stand To-day Auditor Admits Campaign to Raise Fare Was Charged to I.

On February 8, 1927, the [[New York City Board of Transportation]] informed the New York State Transit Commission that work on the Times Square station was sufficiently completed to enable the start of train service beginning on February 19, 1927 with the completion of work to a point between Eighth Avenue and Seventh Avenue. Plans for the construction of an extension of the line to between Eighth Avenue and Ninth Avenue to provide a physical connection with the IND Eighth Avenue Line were underway.<ref>{{Cite news |date=February 9, 1927 |title=Times Square Tube Station To Open Soon: Train Operation on Queensboro Line Will Begin Feb. 19 |work=The Brooklyn Citizen |url=https://www.newspapers.com/clip/35063157/the-brooklyn-citizen/ |access-date=July 12, 2022}}</ref>

On March 1, 1927, the opening of the line was set for March 15, the third time an opening date was set for the line. Work had been postponed given the amount of work that remained to be completed. The opening of the line was about a year behind the April 29, 1926 date specified in the contract. The delay was the result of surprisingly difficult construction. The Board of Transportation had withheld retained percentages, as allowed in the contract, penalizing the contractor, and trying to incentivize it to speed up work. No retained percentages were provided to the contractor until February 1927.<ref name="OpeningNear" /> The Flushing Line was extended to [[Times Square (IRT Flushing Line)|Times Square]] on March 14, 1927.<ref name="nyt-1927-03-1522">{{Cite news |date=March 15, 1927 |title=New Queens Subway Opened to Times Sq.; Service Starts at Once After a Celebration by City and Civic Leaders |language=en-US |work=The New York Times |url=https://www.nytimes.com/1927/03/15/archives/new-queens-subway-opened-to-times-sq-service-starts-at-once-after-a.html |access-date=July 10, 2022 |issn=0362-4331}}</ref><ref>{{Cite book |url=https://archive.org/stream/annualreport7192newy#page/12/mode/2up/search/pelham |title=State of New York Department of Public Service Metropolitan Division Transit Commission Seventh Annual Report For The Calendar Year 1927 |date=1928 |publisher=New York State Transit Commission |page=13 |language=en}}</ref>

For the [[1939 New York World's Fair]], the [[Willets Point Boulevard (IRT Flushing Line)|Willets Point Boulevard]] station was rebuilt and centered on 123rd Street, just west of where the station originally lay. Some remnants of the old station are still visible; ironwork tends to indicate where the older outside-platform stations were, and the remains of the fare entry area can be seen east of the current station. The original [[Willets Point, Queens|Willets Point Boulevard]] station was a "minor" stop on the Flushing Line; it had only two stairways and short station canopies at platform level. It was rebuilt into the [[World's Fair (IRT Flushing Line)|much larger station]] in use today, and the ramp used during two World's Fairs still exists, but is only used during special events, such as the [[US Open (tennis)|US Open]] for [[tennis]]. Express service to the World's Fair began on the Flushing Line on April 24, 1939.<ref>{{cite news|title=Fast Subway Service to Fair Is Opened|url=https://timesmachine.nytimes.com/timesmachine/1939/04/25/91572482.pdf|newspaper=The New York Times|date=April 25, 1939|page=1|access-date=October 2, 2011}}</ref>

Currently and historically, the IRT assigned the number [[7 (New York City Subway service)|7]] to its Flushing Line subway service, though this did not appear on any equipment until the introduction of the [[R12 (New York City Subway car)|R12 rolling stock]] in 1948.

In 1914, the PSC chairman and the commissioner committed to building the line toward Bayside.

On October 17, 1949, the joint BMT/IRT service arrangement ended. The Flushing Line became the responsibility of IRT.

During the joint service period, the elevated stations on the Astoria and Flushing Lines were only able to fit nine 51-foot-long BMT elevated or IRT cars, the rough equivalent of seven 67-foot-long BMT subway cars. After the BMT/IRT dual services ended in 1949, the [[New York City Board of Transportation]] announced that the Flushing Line platforms would be lengthened to 11 IRT car lengths, and the Astoria Line platforms extended to 9 BMT car lengths.

Identification of Trains and Routing Automatically (IDENTRA) was implemented on the line in the 1957 and used until 1997, when a route selector [[punch box]] with B1 Astoria, local/express buttons was installed at the 10/11 car marker on the upper level of Queensboro Plaza.<ref name="subsig">[http://www.thejoekorner.com/out-the-front/signals.htm "Subway Signals"], thejoekorner.com</ref><ref>{{cite web|url=http://www.highbeam.com/doc/1G1-198995503.html|archive-url=https://web.archive.org/web/20160222182320/https://www.highbeam.com/doc/1G1-198995503.html|archive-date=February 22, 2016|title=Roots of an Evolution: Fifty Years of Automated Train Control in New York|work=Railway Age|date=April 1, 2009|access-date=September 15, 2015|author=Conningham, Joseph J.|quote=The latter included an installation on the IRT Flushing (7) line of the US&S IDENTRA (Identification of Trains and Routing Automatically) system in which a passive coil on the lead car actuated wayside readers to set routes and station signs.|via=HighBeam}}</ref> IDENTRA used a removable round circular disc type [[radio antenna]] assembly, slide-mounted on the small mounting brackets that were attached on the front of [[R12 (New York City Subway car)|R12]], [[R14 (New York City Subway car)|R14]], [[R15 (New York City Subway car)|R15]], and [[R17 (New York City Subway car)|R17]] cars that were assigned to the 7 route, which had been used on the line since 1948. Similar to the use of radio transponders in the CBTC installation, the system used the antennas to determine whether a train was running local or express, and then accordingly switched the track at interlockings near the Queensboro Plaza and Flushing–Main Street stations. This move reduced the number of signal towers on the line from 9 to 2<ref name=subsig/><ref name=rpa/> and theoretically allowed to operate 37 eleven-car trains instead of only 30 nine-car trains per hour.<ref>{{cite journal|title=Automatic Control of Switches In New York Subway|journal=Railway Signaling and Communications|date=1954|issue=4|page=33}}</ref><ref name="LISJ-StillCrawls-1957"/> The consolidated signal system was in use by 1956 while the selector system was in service by 1958.<ref name="AnnualReport1963">{{Cite book|title=Annual Report — 1962–1963|publisher=New York City Transit Authority|year=1963}}</ref> However, in practice, train frequencies were not necessarily increased.

As with much of the rest of the subway system, the IRT Flushing Line was allowed to deteriorate throughout the 1970s to the late 1980s. Structural defects that required immediate attention at the time were labeled as "Code Red" defects or "Red Tag" areas, and were numerous on the Flushing Line. Some columns that supported elevated structures on the Flushing Line were so shaky that trains did not run when the wind speed exceeded {{convert|65|mph|km/h}}. This was particularly widespread on the Flushing and the [[BMT Jamaica Line]]s.
[[File:On May 13, Residents of Queens Are Going To Be Mad As Hell.jpg|thumb|Poster announcing the Flushing Line rehabilitation project in 1985.]]
On May 13, 1985, a 4{{1/2}}-year-long, $70 million project to overhaul the IRT Flushing Line commenced.<ref name=":8">{{Cite news|url=https://www.newspapers.com/clip/24553366/more_delays_ahead_for_no_7_line/|title=More delays ahead for No. 7 line|last=Slagle|first=Alton|date=December 2, 1990|work=New York Daily News|access-date=November 5, 2018}}</ref> It forced single-tracking on much of the line during weekends, and the elimination of express service for the duration of the project. The MTA advertised this change by putting leaflets in the ''New York Times'', the ''[[Staten Island Advance]]'', the ''[[Daily News (New York)|Daily News]]'', and ''[[Newsday]]''. The project laid new track, replaced or repaired concrete and steel structures, replaced wooden station canopies with aluminum, improved lighting, improved signage, and installed new ventilation and pumping equipment. Expanded service was provided when the Mets played home games or when there were sporting events in [[Flushing Meadows–Corona Park]]. Paradoxically, Flushing local trains had better on-time performance during the construction than before it started.

The $70 million rehabilitation project on the Queens Boulevard concrete viaduct was completed six months early, and <7> express service was restored on August 21, 1989, without stopping at [[61st Street–Woodside (IRT Flushing Line)|61st Street–Woodside]].<ref name=":32">{{Cite book|url=https://books.google.com/books?id=_5hq0ippLSwC&q=Manhattan+Bridge|title=Annual Report on ...

The reason for the discontinuance on the Flushing express was because the MTA felt it took too long to transfer between locals and expresses. The service was also due to fears of delays on the line when locals and expresses merged after 33rd Street–Rawson Street. The change was supposed to enable local trains to stop at 61st Street every four minutes (15 trains per hour) during rush hours, but according to riders, the trains arrived every 8–10 minutes. The community opposition led to service changes, and expresses began stopping at Woodside again a few months later.<ref>{{cite web|last1=Feinman|first1=Mark S.|title=The New York Transit Authority in the 1980s|url=https://www.nycsubway.org/wiki/The_New_York_Transit_Authority_in_the_1980s|work=www.nycsubway.org|access-date=November 8, 2016}}</ref>

On weekends between January 19 and March 11, 7 service was partially shutdown so that switches at the Fisk Interlocking could be replaced. The $5 million project was not done in conjunction with the work between 1985 and 1989 because the 23-year old switches were not due for replacement.<ref name=":8" />

In the mid-1990s, the MTA discovered that the Queens Boulevard viaduct structure was unstable, as rocks that were used to support the tracks as [[Track ballast|ballast]] became loose due to poor drainage, which, in turn, affected the integrity of the concrete structure overall. <7> express service was suspended again between 61st Street–Woodside and [[Queensboro Plaza (IRT Flushing Line)|Queensboro Plaza]]; temporary platforms were installed to access the express track in the four intermediate stations.<ref name="NYT 1995 r939">{{cite web |last=Pérez-Peńa |first=Richard | title=Along the Subway, a Feat in Concrete | website=The New York Times | date=October 9, 1995 | url=https://www.nytimes.com/1995/10/09/nyregion/along-the-subway-a-feat-in-concrete.html | access-date=October 8, 2024}}</ref> The work began on April 5, 1993.<ref>{{Cite web|url=https://www.flickr.com/photos/127872292@N06/35119874302/in/album-72157652636594213/|title=April 1993 Map Information|date=April 1993|website=Flickr|publisher=New York City Transit Authority|language=en-us|access-date=October 7, 2018}}</ref><ref>{{Cite news|url=https://www.newspapers.com/clip/24541574/daily_news/|title=The repairs we're making on the 7 line will take some time.

In January 2012, the MTA selected [[Thales Group|Thales]] for a $343 million contract to set up a [[communications-based train control]] (CBTC) system as part of the plan to automate the line. This was the second installation of CBTC, following [[Signaling of the New York City Subway#Canarsie Line CBTC|a successful implementation on the BMT Canarsie Line]].

The MTA chose the Flushing Line for the next implementation of CBTC because it is also a self-contained line with no direct connections to other subway lines currently in use.
