The R188 is a class of 506 new technology (NTT) New York City Subway cars built by Kawasaki Heavy Industries for the A Division. The cars displaced R62As that operated on the 7 and <7> services in order to automate the IRT Flushing Line.
In addition to providing six extra 11-car trains for the 7 Subway Extension, the R188s will allow twenty R62A cars to be freed up for the other IRT services.
The R188s are numbered 7211-7590 and 7811-7936. Cars 7211-7590 are former R142As that were converted, cars 7811-7898 are new cars built to supplement the increase in 7 service, and cars 7899-7936 are new "C" cars built to extend converted R142A sets to six cars (other R142A five-car sets had one of their cars rebuilt into "C" cars).
The R188s are equipped with the latest control systems, HVAC, and public address system to guarantee the utmost safety and passenger comfort. They are nearly identical to the R142As, but are equipped with CBTC. Therefore, these cars are compatible only with the converted R142As that feature CBTC.
Like the R142s, R142As, and R143s, the R188s feature the electronic strip map with all stops on the 7 route with an indicator that can be set to either a local or express train.
At the time that the R188 order was placed, forty R62A 11-car trainsets were assigned to the 7 service. The R188 order originally consisted of 186 new cars, as well as 131 converted R142A cars compatible with communication-based train control (CBTC) and an additional 189 R142A conversion kits for MTA, totaling a possible 506 cars, or in other words, 46 11-car trains. Of these 506 cars, 230 are arranged in 5-car sets while the remaining 276 are arranged in 6-car sets. Six extra R188 trainsets were ordered in conjunction with CBTC installation and 7 Subway Extension. The trains are configured so that the five-car consist on each train is located on the Manhattan-bound end and the six-car consist is located on the Main Street-bound end, due to the position of conductor's boards on platforms along the 7 route.
