The R142 is the first mass-produced model class of the newest generation or new technology (NTT) A Division cars for the New York City Subway. It was built by Bombardier Transportation in La Pocatière, Quebec, Canada and Barre, Vermont, U.S. with final assembly performed at Plattsburgh, New York, from 1999 to 2003.^[6] There are 880 cars numbered 6301–7180 and another 150 cars numbered 1101–1250, for a total of 1,030 cars, all arranged as five-car sets. Together with the R142As, they replaced the Redbird trains, including the R26, R28, R29, R33, R33S, and R36.

The R142s and R142As are the first New York City Subway cars to feature recorded announcements. The first R142s were delivered on November 16, 1999, though they initially experienced minor issues that were reported while undergoing testing. Following the completion of non-revenue service testing, the R142s were placed into revenue service on July 10, 2000 as part of its 30-day revenue acceptance test. After successful completion, it entered revenue service on October 20, 2000.^[7] The last R142s were delivered by mid-2003. In January 2019, the MTA proposed mid-life upgrades to the R142 fleet.
