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 {{NYCS trains|Canarsie|type=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 {{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. The first cars (8101–8104) were delivered to the 207th Street Yard on April 30, 2001. 8105–8108 were delivered sometime later in the summer of 2001. The first R143s 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. All cars were delivered by March 2003 with all cars being in service by April 2003.
==Description and features== thumb|left|An LED information screen on an R143 The R143s are numbered 8101–8312. The 212 cars were expected to provide enough service for years, but the fast growth of the Williamsburg neighborhood overloaded the L by mid-2006,<ref>{{cite news |work=New York Daily News |url=http://www.nydailynews.com/archives/news/enuf-trains-ta-cars-surge-riders-article-1.580828 |title=Oh, L, not enuf trains! |url-status=dead |archive-url=https://web.archive.org/web/20140324161849/http://www.nydailynews.com/archives/news/enuf-trains-ta-cars-surge-riders-article-1.580828 |archive-date=March 24, 2014 |date=July 7, 2006 |last=Donohue |first=Pete}}</ref> which resulted in some R160s being placed on the route.
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 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, but also run on the J/Z. The R143s are very similar to the R160s and R179s, but while the R143s can run with the R160s, both types cannot run with the R179s 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, but since 2020, they were retrofitted to include the 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 interior LCD screens (behind the electronic signs on the sides of the trains).{{Citation needed|date=April 2026}}

==History== ===Timeline of contract=== thumb|left|Builders plate of the R143s 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>

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 R160As in February 2008. OPTO service was also tested on the L during mid-2005, but it ended due to safety issues following the London Transport Bombings.<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>

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 on December 11, 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>
