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.
