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.
The R188 order originally consisted of a possible 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 are to be purchased. Of these new cars, 110 cars will go to make up 10 new eleven car trains, while the remaining 36 cars will be "C" cars that will 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) will still result from this order.[2]
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 take the contract citing the small order and large requirement for engineering resources. The contract is specified at $87,094,272 for the base order, which consists of 33 cars (23 new cars and 10 conversions), and $384,315,168 for the option order, which consists of 473 cars (123 new cars, and 350 conversions) for a total price of $471,409,440. The R142A conversion set from the base order is scheduled to be completed during the 4th quarter of 2011 while the 23 new cars are scheduled for delivery by the 4th quarter of 2012. The first 88 option cars (eight 11 car sets) are scheduled to be delivered from the 4th quarter of 2013 through the 2nd quarter of 2014 while the remaining 35 new cars and the 350 conversions are scheduled for delivery and conversion from the 1st quarter of 2014 through the 4th quarter of 2015. The conversion cars under the base contract will be converted at Kawasaki's Yonkers facility while the rest of the conversions are scheduled to take place on property by a joint team of Kawasaki and NYCTA personnel at the 207th Street Overhaul Shop.[3][4]
In March 2011, five R142As were taken out of service to be retrofitted with CBTC as a prototype for the R188s. Five more R142As were taken out of service for this same reason in June 2011.[5]
As of December 2011, the first 10 car conversion set has been completed and delivered for on-site testing.
As of December 16th, 2011, an additional modification to the contract was made. In the latest revision, only 103 new cars will be purchased to form 8 new 11 car trains. Likewise, the number of conversion cars will be 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 have opted to convert two additional R142A train sets in place of manufacturing two new sets.[6]
