The R188 is an A Division new technology (NTT) car constructed by the for the New York City Subway. The MTA is displacing the R62As from the 7 <7> services with these cars to automate the IRT Flushing Line. The R188 is part of both the fourth and fifth generation of New York City Subway A Division rolling stock. 380 R142As are converted to R188s, along with deliveries of 126 new R188 cars. The R188s comprise fleet numbers #7211-7590 and #7811-7936.
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.
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.
According to the 2010–2014 capital plan, 146 new cars were to be purchased. Of these new cars, 110 cars would go to make up 10 new 11-car trains, while the remaining 36 cars were to be "C" cars that would go to expanding 36 CBTC upgraded R142A 5-car sets (360 existing cars) to 6-car length. The original planned total of 46 11-car trains (506 cars) would still result from this order.
