The R142A is a class of 220 (formerly 600) new technology (NTTs) New York City Subway cars built by Kawasaki Heavy Industries for the A Division. Along with the R142s, the cars replaced all of the remaining Redbird trains (R26, R28, R29, R33, R33 WF, R36, and R36 WF).
The R142As were originally numbered 7211–7810, but only cars 7591–7810 remain as R142As; cars 7211–7590 were converted to R188s.
The R142A contract was divided into three sub-orders: 400 main order cars (7211–7610), 120 option order cars (7611–7730), and eighty cars built under a supplemental contract (R142S) in 2003-2004 to supplement the R142As (7731–7810). Regardless of the sub-order differences, all R142As are mechanically and physically identical each other.
The R142A, along with the R142, is the first model class of the newest generation of IRT cars for the subway system. built these cars from 1999 to 2004 at Kobe, Hyōgo, Japan with final assembly performed at Kawasaki Railcar Corp.'s American Facilities located at Lincoln, NE, USA & Yonkers, NY, USA.
