The R188 is an A Division car for the New York City Subway. The MTA is planning to displace the R62As from the 7 train with these cars and to automate the IRT Flushing Line.


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 eleven 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]

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 eleven 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 eleven car trains (506 cars) would still result from this order.[2][3]


The 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.

In the latest revision, however, only 103 new cars were to be purchased to form 8 new 11 car trains. Likewise, the number of conversion cars was altered to 370. This change was made with the knowledge that only two growth sets 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.[4]

The 10 converted R142A cars from the base order, numbered 7211-7220, were completed in December 2011 at Kawasaki's Yonkers facility; cars 7221-7230 have also undergone conversion at Kawaski's Yonkers facility.[5] They were delivered to Corona Yard for testing on the Flushing line in 2012.[6][7][8][9][10] The 23 new cars from the base order are scheduled for delivery by the 4th quarter of 2012. The first 66 option cars (six 11 car sets) are scheduled to be delivered from the 4th quarter of 2013 through the 2nd quarter of 2014 while the remaining 37 new cars and the 370 conversions are scheduled for delivery from the 1st quarter of 2014 through the 4th quarter of 2015.[11][12]

According to the latest update, the MTA expects to have 8 conversion sets in service by the time that the Flushing Line Extension is opened for revenue service. In addition, the breakdown of the trainsets has been disclosed. Breakdown is as follows: A-C-B-B-A+A-B-B-B-C-A; where dashes signify link bars and the addition sign denotes couplers.[13]
