The R142A is the second order of new technology cars (NTTs) for the A Division of the New York City Subway. These cars were built by Kawasaki Heavy Industries in Kobe, Hyōgo, Japan and Lincoln, Nebraska, U.S. with final assembly performed at Yonkers, New York. Together with the R142s, they replaced the Redbird trains, including the R26, R28, R29, R33, R33S, and R36. The R142A fleet initially comprised 600 cars, arranged as five-car units.
The first R142As were delivered on December 20, 1999. The cars initially experienced minor issues while undergoing testing, but entered service on July 10, 2000, as part of its 30-day revenue acceptance test. After successful completion, the cars entered revenue service by November 2, 2000. The fleet initially ran on the 4 and 6 services of the IRT Lexington Avenue Line. The R142As, along with the R142s, are the first New York City Subway cars to feature recorded announcements.
In 2010–2016, 380 cars (7211–7590) were retrofitted with communications-based train control (CBTC) for the automation of the Flushing Line and became part of the R188 fleet, leaving 220 cars (7591–7810) in the R142A fleet. In January 2019, the MTA has proposed mid-life upgrades to the remainder of the R142As.
