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 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.^[7] The fleet first entered passenger service on November 9, 2013, and the final cars were delivered in June 2016.
