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 <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 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 similar to the R142As, but are compatible only with the converted R142As that feature CBTC.
Timeline of Contracts
|# of conversion cars||# of new C cars||# of new A & B cars|
|Original order||140||46||320[note 1]|
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.
In the latest revision, however, only 88 new cars were to be purchased to form 8 new 11-car trains, with 38 "C" cars, rather than ten 11-car trains. Likewise, the number of conversion cars was altered to 370. This change was made with the knowledge that only two ten-car R62A growth sets for the mainline IRT would be needed, as opposed to the projected four sets, and thus the MTA and Kawasaki opted to convert two additional R142A train sets in place of manufacturing two new sets. The MTA also decided to have Kawasaki perform all of the conversions at the Yonkers plant instead of 207th Street Shop as part of that contract modification.
The R188 contract was awarded in spring 2010 to Kawasaki Heavy Industries, who won by default since only two manufacturers qualified and Bombardier Transportation opted not to bid on the contract citing the small order and large requirement for engineering resources. The contract was specified at $87,094,272 for the base order, which consisted of 33 cars (23 new cars and 10 conversions), and $384,315,168 for the option order, which consisted of 473 cars (123 new cars, and 350 conversions) for a total price of $471,409,440.
According to a February 2012 update, the MTA had expected to have 8 conversion sets in service by the time that the 7 Subway Extension is opened for revenue service. In addition, the breakdown of the trainsets has been disclosed. Operationally, the R188s are coupled as such: A-C-B-B-A+A-B-B-B-C-A; where dashes signify link bars and the addition sign denotes couplers. Thirty-eight R142A B cars, therefore, will be converted into R188 "C" cars, in addition to the 38 deliveries of new "C" cars (not including the "C" cars in the eight new 11-car sets).
The 10 converted R142A cars from the base order (7211-7220) were completed in December 2011 at Kawasaki's Yonkers facility, and were delivered for testing on the Flushing line in 2012. The 23 new cars from the base order (two eleven-car sets, 7811-7832, and one conversion set "C" car, 7899) were completed in mid-2012, delivered in November 2013, and entered service in December 2013. The 66 new option cars (7833-7898) were also completed in mid-2012 and have been delivered, while the remaining 37 new cars and the 370 conversions were set to be converted and delivered from February 2014 until the 4th quarter of 2015.
On November 9, 2013, the first R188 train, consisting of cars 7811-7821, were placed in service on the 7 train as part of its 30-day revenue acceptance test. After successful completion, it entered revenue service by December 15, 2013. By July 2014, the delivery schedule had slipped by about 6–7 months. However, delivery of the cars sped up; all remaining R188 cars were expected to be delivered by the end of July 2016, but the last R188 cars were delivered in late June 2016.
In June 2016, one train of R188s had its destination signs modified with green circle/red diamond LED signs, similar to those on the R62As originally used on the 7 (and currently on the 6). This modification was done presumably due to the fact that passengers on the 7 cannot visually differentiate between an express train and local train, despite the announcements and digital signage. It is unknown if the remainder of the R188 fleet will be retrofitted with this feature.

- This was the total of 131 converted R142A cars compatible with communication-based train control (CBTC) and an additional 189 R142A conversion kits. The option order of 473 cars was broken down as follows: 163 new R188 cars, conversion of 124 R142/R142A cars, and providing 186 conversion kits of R142/R142As.
