New Technology Train

New Technology Train (NTT) is the collective term for the modern passenger fleet of the New York City Subway entering service since the turn of the 21st Century. This includes the current R142, R142A, R143, R160, and R188 models, the R179 model currently under construction, and the planned R211 model. 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. Much of the engineering and construction efforts for the fleet have been done by Kawasaki Heavy Industries and Bombardier Transportation.
