The R188 is an A Division car for the New York City Subway. The MTA is displacing the R62As from the 7 <7> services with these cars and 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; many fourth-generation R142As are being converted to R188s, along with deliveries of new R188 cars.

In addition to providing six extra 11-car trains for the 7 Subway Extension, the R188s will allow twenty R62A expansion cars to be freed up for the other IRT services.


Timeline of trainsets[edit]

All planned
# of conversion cars # of new C cars # of new A & B cars
Total Total Total
Original order[1] 140 46 320[note 1]
10 130 3 43 20 300
360 46 100
10 350 3 43 20 80

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. Given this number, it can be deduced that 230 of these cars will be arranged in 5-car sets while the remaining 276 cars will be arranged in 6-car sets.[1] Six extra R188 trainsets were ordered in conjunction with CBTC installation and 7 Subway Extension.

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.[2]

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.[3]


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 the latest update, the MTA expects to have 8 conversion sets in service by the time that the 7 Subway Extension is opened for revenue service in November 2014. 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).[4]

Entering revenue service[edit]

The 10 converted R142A cars from the base order (numbers 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 (numbered 7811-7832 and 7899, which is the 'C' car for the conversion cars) were completed in mid-2012, delivered in November 2013, and entered service in December 2013. The new 66 option cars (numbers 7833-7898) were also completed in mid-2012 and are currently being delivered since November 22, 2013, while the remaining 37 new cars and the 370 conversions are currently being converted and delivered since February 2014 until the 4th quarter of 2015.[5][6]

On November 9, 2013, the first R188 train, consisting of cars 7811-7821, were placed in or entered service on the 7 train as part of its 30 day revenue acceptance test.[7] After successful completion, it entered revenue service by December 15, 2013. Since then, several more R188 trainsets have been built. [8]

  1. ^ 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.
