The R188 is a class of new technology (NTT) New York City Subway cars built by Kawasaki Heavy Industries for the A Division. The fleet entered service in 2013, displacing the mid-1980s–era R62A cars that operated on the 7 and <7> services, in conjunction with the automation of the IRT Flushing Line's signal system with communications-based train control (CBTC). The R188 order also expanded the 7's fleet as part of the 7 Subway Extension, which opened in 2015.
Of the 506 cars in the fleet, only 126 were built brand-new; the remaining 380 cars were originally part of the R142A fleet that entered service in 2000, before being upgraded to R188s with the installation of CBTC equipment. The fleet first entered passenger service on November 9, 2013, and the final cars were delivered in June 2016.
