The R142A, along with the R142, are the first and second part of the fourth generation of somewhat similar new technology cars (NTTs) for the A Division of the New York City Subway. These cars were built by Kawasaki Heavy Industries in Japan. Along with the R142s, they replaced the Redbird trains, including the R26, R28, R29, R33, R33 WF, R36, and R36 WF. The R142As were built as fleet numbers #7211–7810, but only the cars from #7591–7810 are currently R142As; cars #7211–7590 were converted into R188s. A total of 380 R142As were converted into R188s for the 7, while the remaining 220 cars remain unconverted.
The R142A cars were built by at Kobe, Hyōgo, Japan with final assembly performed at Kawasaki Railcar Corp.'s American Facilities located at Lincoln, NE, USA & Yonkers, NY, USA from 1999 through 2004, and have many of the same features as the R142, built by Bombardier. The 400 R142A cars of the main order are numbered #7211–7610; the 120 option cars are numbered #7611–7730. Eighty cars, built under a supplemental contract as the R142S, were built by Kawasaki in 2003-04 to supplement the R142As. They are numbered as #7731–7810. They are mechanically and physically identical to all other R142As, and are considered part of the R142A fleet.
