New Technology Train
New Technology Train (NTT) is the collective term for the modern passenger fleet of the New York City Subway that has entered service since the turn of the 21st century. This series includes the current R142, R142A, R143, R160, R179, R188 and R211 models, along with the planned R262 and R268 models. Two prototypes, the R110A and R110B, were used to test the features that would be found on all NTTs today.
Sometimes referred to as New Millennium Trains, they are known for improvements in technology, energy efficiency, reliability, and comfort along with advanced passenger information systems. All of these trains are capable of operating with communications-based train control (CBTC)—which can allow for automatic train controls and compatibility with updated signal systems—and either already have CBTC or are scheduled to be retrofitted with the system. Much of the engineering and construction efforts for the fleet have been done by Kawasaki Heavy Industries and Bombardier Transportation, with Alstom also participating in the construction of the R160 fleet.
This is a list of all NTTs operated by the New York City Subway, as well as future trains and retired trains of the MTA.
The New Technology program emerged from modernization efforts by the Metropolitan Transportation Authority (MTA) beginning in 1982, when the subway "was on the verge of collapse". The New Technology program officially began in 1988, the first effort at a technologically advanced subway car since the R44 in the early 1970s. In 1989, the MTA awarded contracts for two prototype test trains: the R110A (contract R130) for the A Division built by Kawasaki Heavy Industries, and the R110B (contract R131) for the B Division built by Bombardier Transportation. The two New Technology test trains (NTTTs) began service in June 1993, testing features that would be implemented on future mass-production orders. Both trains were taken out of service by 2000, due to multiple issues with the trains.
In 1997, the first mass order of New Technology trains was placed for the R142 and R142A trains of the A Division (awarded to Bombardier and Kawasaki respectively), in order to replace the final 1,410 Redbird cars in operation. In 1998, a smaller contract of 212 cars, consisting of 100 in the base order and 112 in the optional order, was awarded to Kawasaki Heavy Industries, to build the R143 model for the B Division's BMT Eastern Division (primarily the BMT Canarsie Line's L train). The first R142s and R142As entered service beginning in July 2000. The R143s began operation in February 2002.
In July 2002, the MTA awarded contracts to Kawasaki and Alstom for the R160 order for the B Division, with options for up to 1,700 cars to replace many 1960s- and 1970s-era cars. The first R160 train, built by Kawasaki under the contract R160B, began service on August 17, 2006, on the N. The initial 660-car base order was filled by October 2008, with a total of 1,662 cars delivered by May 6, 2010.
On May 5, 2010, Kawasaki was awarded the contract for the R188 A Division order, to provide 46 CBTC-ready 11-car trains for the IRT Flushing Line (7 and <7> trains). Unlike the other orders, the R188 constructed only 126 new subway cars, with the remaining 380 cars consisting of converted R142As. The first R188s entered service on November 9, 2013.
On June 4, 2012, Bombardier was awarded the R179 contract for 300 new B Division cars, to replace the 50 R42s on the BMT Jamaica Line (J and Z trains). In December 2012, preliminary designs began on the R211 B Division contract, which entails 940 cars in order to expand the system fleet, and to replace the R46 fleet, and the R44 fleet of the Staten Island Railway; both models were built in the 1970s. Both the R179 and R211 orders were supposed to replace the 222 remaining R32 cars, which were built in the 1960s and have run well past their expected lives, by the year 2022., however, in January 2020, it was decided that the R179 fleet was to replace all remaining R32s. The R179 order fell significantly behind schedule, with the first test train delivered in September 2016.
