The R143 was the first "B" Division order of the NTT series, and the first {{Convert|60|ft|4=2|adj=on}} B Division car built for the New York City Subway system since the R42s delivered in 1969. A total of 212 cars were built, all arranged as four-car sets. First delivered in late 2001, they entered a 30-day period of revenue service testing on December 4, 2001, and officially entered service on the Canarsie Line on February 12, 2002. By March 2003, all cars had been delivered.

The R143s are numbered 8101–8312. The 212 cars were expected to provide enough service for years, but the fast growth of the [[Williamsburg, Brooklyn|Williamsburg]] neighborhood overloaded the [[L (New York City Subway service)|L]] by mid-2006.<ref>[[New York Daily News]], [http://www.nydailynews.com/archives/news/enuf-trains-ta-cars-surge-riders-article-1.580828 Oh, L, not enuf trains!] {{Webarchive|url=https://web.archive.org/web/20140324161849/http://www.nydailynews.com/archives/news/enuf-trains-ta-cars-surge-riders-article-1.580828 |date=March 24, 2014 }}, July 7, 2006</ref>

The R143s are the first {{Convert|60|ft|4=2|adj=on}} B Division cars built for the New York City Subway system since the [[R42 (New York City Subway car)|R42]] from 1969, the first NTT model for the B Division, and the first automated fleet in the subway system. They are currently based at [[East New York Yard]] and assigned to the [[L (New York City Subway service)|L]], but sometimes run on the J/Z. The R143s are very similar to the [[R160 (New York City Subway car)|R160]]s and [[R179 (New York City Subway car)|R179s]], but the three car types are not interoperable with each other due to electrical incompatibilities between them.<ref name="NYTimes-NYCSPromiseInfo-Nov2005">{{cite news |last=Chan |first=Sewell |author-link=Sewell Chan |title=New Subway Cars Promise All Kinds of Information |newspaper=[[The New York Times]] |date=November 30, 2005 |url=https://www.nytimes.com/2005/11/30/nyregion/30car.html |access-date=October 27, 2007 |archive-date=March 15, 2023 |archive-url=https://web.archive.org/web/20230315015712/https://www.nytimes.com/2005/11/30/nyregion/new-subway-cars-promise-all-kinds-of-information.html |url-status=live }}</ref><ref>{{Cite web|url=http://www.geniustransitchallenge.ny.gov/sites/default/files/resources/page-4/technical-specification-car-equipment.11.pdf|title=Specifications for Furnishing and Delivering Passenger Cars for the New York City Transit System|date=July 2017|website=geniustransitchallenge.ny.gov|page=R160 1–2|access-date=August 6, 2017|archive-date=August 9, 2017|archive-url=https://web.archive.org/web/20170809072754/http://www.geniustransitchallenge.ny.gov/sites/default/files/resources/page-4/technical-specification-car-equipment.11.pdf|url-status=live}}</ref><ref>{{Cite web|url=http://web.mta.info/mta/news/books/pdf/160523_1030_Transit.pdf|title=Transit & Bus Committee Meeting May 2016|date=May 2016|website=mta.info|publisher=Metropolitan Transportation Authority|access-date=September 10, 2016|archive-date=September 15, 2016|archive-url=https://web.archive.org/web/20160915150058/http://web.mta.info/mta/news/books/pdf/160523_1030_Transit.pdf|url-status=dead}}</ref>

Like the R142s, R142As, and R188s, the R143s feature electronic strip maps. Originally, they only depicted stops on the [[L (New York City Subway service)|L]], but since 2020, they were retrofitted to include the [[J/Z (New York City Subway service)|J/Z]]. These newer installations depict the L and J/Z routes using two separate maps side-by-side, using the same 63-light console.

Unlike the rest of the NTT fleet at the time, the R143s are equipped with interior LED screens, which take the place of the MTA Arts for Transit cards that are usually located there. These screens can display advertisements, public safety announcements, and other information.<ref>{{Cite web|url=https://www.nycsubway.org/perl/show?3648|title=Showing Image 3648|website=www.nycsubway.org|access-date=2018-04-25|archive-date=April 25, 2018|archive-url=https://web.archive.org/web/20180425114606/https://www.nycsubway.org/perl/show?3648|url-status=live}}</ref> Several cars of the NTT fleet were similarly retrofitted with LCD screens after they were delivered, and all subsequent orders are built with these screens. However, the LCD screens have the capability to display multiple colors instead of only red, orange, and green.

=== Communications-based train control ===
{{Unreferenced section|date=April 2024}}
The Transit Authority had projected that 212 Kawasaki-made R143 subway cars would be enough to accommodate ridership demands for years to come, but ridership has risen higher than expected. Therefore, sixty-four new [[R160 (New York City Subway car)|R160A]] cars manufactured by [[Alstom]] were equipped with CBTC so they could run on the L along with the R143s.

==History==
===Timeline of contract===
The contract for the R143 was put out to tender in January 1998. The initial contract called for 100 {{Convert|60|ft|4=2|adj=on}} cars that would come in five-car sets. The new cars would be expected to have automatic PA announcements, high efficiency lighting, emergency intercom and customer alarms, AC propulsion motors, speedometers and event recorders, electronic information display signs, artwork, a central diagnostics monitoring system, microprocessor-controlled air compressor, brake and communication systems, roof-mounted microprocessor-controlled HVAC, and to be compliant with ADA requirements.<ref>{{Cite web|url=http://www.mta.nyc.ny.us/mta/html/eye-nyct.htm|title=R34143 PURCHASE 100 CARS DIVISION 'B' OVER $10M|date=January 27, 1998|website=www.mta.nyc.ny.us|publisher=New York City Transit|access-date=September 18, 2016|url-status=dead|archive-url=https://web.archive.org/web/19980127005906/http://www.mta.nyc.ny.us/mta/html/eye-nyct.htm|archive-date=January 27, 1998|df=mdy-all}}</ref>

[[Kawasaki Heavy Industries Rolling Stock Company|Kawasaki Rail Car Company]] was awarded a $190 million contract for 100 new B Division cars in late December 1998, with an option for 112 more cars.<ref>{{cite news|title=Metro Business; Subway Job to Kawasaki|url=https://www.nytimes.com/1998/12/30/nyregion/metro-business-subway-job-to-kawasaki.html|work=[[The New York Times]]|date=December 30, 1998|access-date=February 18, 2017|archive-date=March 5, 2016|archive-url=https://web.archive.org/web/20160305174803/http://www.nytimes.com/1998/12/30/nyregion/metro-business-subway-job-to-kawasaki.html|url-status=live}}</ref><ref>Kawasaki wins new NYCT car order ''[[Railway Age|The Railway Age]]'' February 1999 page 23</ref> The new design was based on the [[A Division (New York City Subway)|A Division's]] [[R142A (New York City Subway car)|R142A]], which Kawasaki also built,<ref name="Kawasaki" /> and incorporated many features from the [[R110A (New York City Subway car)|R110A]] and [[R110B (New York City Subway car)|R110B prototypes]]. The cars were built with an average cost of about $1.5 million per car.

===Delivery===
Delivery of the cars began in late 2001. A 30-day revenue acceptance testing with one train of eight cars (8101–8108) began on December 4, 2001.<ref>{{cite web|url=http://www.nycsubway.org/cars/r143.html|title=www.nycsubway.org|access-date=August 18, 2006|archive-date=June 14, 2010|archive-url=https://web.archive.org/web/20100614235957/http://nycsubway.org/cars/r143.html|url-status=live}}</ref><ref>{{Cite journal|date=January 2002|title=First run of the R143s|journal=New York Division Bulletin|publisher=Electric Railroaders' Association}}</ref> According to Kawasaki, the test was "extremely successful".<ref name="Kawasaki" /> The cars began running on the Canarsie Line ({{NYCS trains|Canarsie}}) on February 12, 2002, where they have been assigned to.<ref name=NYTimes-R160-1700-July2002>{{cite news|last1=Kennedy|first1=Randy|title=1,700 Subway Cars to Be Built Under Largest Such Contract in New York History|url=https://www.nytimes.com/2002/07/31/nyregion/1700-subway-cars-to-be-built-under-largest-such-contract-in-new-york-history.html|work=[[The New York Times]]|date=July 31, 2002|page=B3|access-date=February 18, 2017|archive-date=May 10, 2017|archive-url=https://web.archive.org/web/20170510083809/http://www.nytimes.com/2002/07/31/nyregion/1700-subway-cars-to-be-built-under-largest-such-contract-in-new-york-history.html|url-status=live}}</ref> All 212 cars were delivered by March 2003.<ref>{{cite journal|title=Kawasaki completes NYCT R143 order.

Along with displacing older equipment from the Canarsie Line, the R143s also displaced the R42s on the now-extended weekend {{NYCS|M}} shuttle service on the [[BMT Myrtle Avenue Line]], when that line became the first BMT Eastern Division line to be placed in a weekend [[One Person Train Operation]] (OPTO) service. The R143s on the M were later displaced by the [[R160 (New York City Subway car)|R160As]] in February 2008. OPTO service was also tested on the L during mid-2005, but it ended due to safety issues.<ref>[https://www.nytimes.com/2005/06/20/nyregion/20subway.html?_r=0 On L Train, Drivers Perform Solo, Without Conductors, June 20, 2005, page B3]</ref><ref>{{Cite news |url=https://www.nytimes.com/2005/09/24/nyregion/24subway.html |title=Conductors Are Returning to the Subway's L Line |work=The New York Times |date=September 24, 2005 |access-date=February 18, 2017 |archive-date=December 20, 2013 |archive-url=https://web.archive.org/web/20131220222110/http://www.nytimes.com/2005/09/24/nyregion/24subway.html |url-status=live |last1=Lee |first1=Jennifer 8. |last2=Rahimi |first2=Shadi }}</ref>

Cars 8205–8212 were originally delivered with experimental Siemens SITRAC traction systems, that would be later found in [[R160 (New York City Subway car)|R160B]] cars 8843–9102. These cars were eventually refitted with the Bombardier MITRAC traction systems found on all other R143s.<ref>{{cite book |last=Samsone |first=Gene |date=October 25, 2004 |title=New York Subways: An Illustrated History of New York City's Transit Cars |url=https://books.google.com/books?id=6WFHNSXBpocC&q=R143+siemens+test&pg=PA282 |location=Baltimore, MD |publisher=JHU Press |page=282 |isbn=0801879221 |access-date=November 19, 2020 |archive-date=March 15, 2023 |archive-url=https://web.archive.org/web/20230315214421/https://books.google.com/books?id=6WFHNSXBpocC&q=R143+siemens+test&pg=PA282 |url-status=live }}</ref>

On April 18, 2004, an eight-car R143 train overshot the bumper at Eighth Avenue after the operator suffered a possible seizure.

On June 21, 2006, another eight-car R143 train overshot the bumper, this time at the end of the tracks in the [[Canarsie Yard]] after the operator suffered a seizure. The first car, 8277, suffered significant damage and was stripped of damaged parts before being sent to the Kawasaki plant in [[Yonkers]] to receive repairs. The other cars in the set (8278–8280) suffered minor body damage and were moved to the 207th Street Yard and repaired. Eventually, 8277 was sent back to New York City Transit property and repaired. By 2016, car 8277 was finally recoupled with 8278–8280, but the consist needed component upgrades to become operational.<ref>{{Cite magazine|date=April 2016|title=New York City Subway Car Update|url=https://erausa.org/pdf/bulletin/2010s/2016/2016-04-bulletin.pdf|magazine=The Bulletin|publisher=Electric Railroaders' Association|access-date=March 30, 2016|page=19|archive-date=June 15, 2022|archive-url=https://web.archive.org/web/20220615190104/https://erausa.org/pdf/bulletin/2010s/2016/2016-04-bulletin.pdf|url-status=live}}</ref> The set returned to service in December 2017.<ref>{{Cite magazine|date=February 2018|title=New York City Subway Car Update|url=https://erausa.org/pdf/bulletin/2010s/2018/2018-02-bulletin.pdf|magazine=The Bulletin|publisher=Electric Railroaders' Association|access-date=January 28, 2022|page=7|archive-date=June 14, 2022|archive-url=https://web.archive.org/web/20220614211833/https://erausa.org/pdf/bulletin/2010s/2018/2018-02-bulletin.pdf|url-status=live}}</ref>

In 2017, a set of R143s was equipped with measuring gauges to test out the curve radius and gangway flex in the existing {{Convert|60|ft|m|2|abbr=|adj=on}}-long cars in order to collect data for evaluating the [[R211 (New York City Subway car)|R211T]] order,<ref>{{Cite magazine|date=May 2017|title=New York City Subway Car Update|url=https://erausa.org/pdf/bulletin/2010s/2017/2017-05-bulletin.pdf|magazine=The Bulletin|publisher=Electric Railroaders' Association|access-date=January 28, 2022|page=20|archive-date=June 15, 2022|archive-url=https://web.archive.org/web/20220615190057/https://erausa.org/pdf/bulletin/2010s/2017/2017-05-bulletin.pdf|url-status=live}}</ref> which began running in revenue service on February 1, 2024.<ref>{{cite web | last=Brachfeld | first=Ben | title=New 'open gangway' R211 subway cars enter service on the C line between Brooklyn & Manhattan | website=amNewYork | date=February 1, 2024 | url=https://www.amny.com/transit/open-gangway-r211-subway-cars-c-line/ | access-date=February 2, 2024 | archive-date=February 1, 2024 | archive-url=https://web.archive.org/web/20240201212333/https://www.amny.com/transit/open-gangway-r211-subway-cars-c-line/ | url-status=live }}</ref>

In September 2020, the interior strip maps for these cars, which originally only depicted stops on the L route, were replaced with combined strip maps that includes stops on both the [[J/Z (New York City Subway service)|J/Z]] and [[L (New York City Subway service)|L]] services.

The R143 is a class of New Technology Train subway cars built by Kawasaki Rail Car Company for the New York City Subway's B Division. Delivered between 2001 and 2003, the cars displaced R40s and R42s that operated on the L service in conjunction with the BMT Canarsie Line's signal system being automated.

The R143 was the first "B" Division order of the NTT series, and the first 60-foot (18.29 m) B Division car built for the New York City Subway system since the R42s delivered in 1969. A total of 212 cars were built, all arranged as four-car sets. First delivered in late 2001, they entered a 30-day period of revenue service testing on December 4, 2001, and officially entered service on the Canarsie Line on February 12, 2002. By March 2003, all cars had been delivered.
