The R179 is a class of 316 new technology (NTT) New York City Subway cars built by Bombardier Transportation for the B Division. The cars are expected to retire all remaining R42s, as well as some R32s.
Originally, the R179 order was supposed to contain 208 cars that were each 75 feet (23 m) long. In the 2010–2014 Capital Program, the order was changed to 290 cars that were 60 feet (18 m) long, similar to the car lengths of the R143 and R160 orders, with options for up to 130 more cars. The majority of the R179s were supposed to be in 300-foot-long (91 m) five-car sets, because the R179s would be replacing the 75-foot-long R44s, which were arranged in 300-foot-long four-car sets. A minority of the R179s were to be arranged in 240-foot-long (73 m) four-car sets. In 2011, the order was reduced to 300 60-foot-long cars with no additional option orders. Because the R44s had been retired prematurely, the setup was reversed, with the majority of the R179s being arranged in 4-car sets.
The $599 million contract for the R179s' construction was awarded to Bombardier in 2012. At the time, the first R179 train was set to be delivered in December 2014 and the last train would be delivered in July 2017. Because of manufacturing defects during the construction process, the timeline for delivery was pushed back two years, and the cost of the contract rose to $735 million. The first R179 cars were delivered in September 2016, and the first test train of eight cars was placed in service in November 2017. The test train passed its 30-day in-service test in December 2017, which allowed the remaining R179s to be placed in service. All cars are expected to be delivered by early 2019. In January 2018, sixteen more cars were added to the order so that there would be 24 five-car sets instead of the 8 originally projected.
The R179s' full numbering range is to be determined. Currently, there are ten cars numbered 3010-3019 arranged as five-car sets, and other cars numbered 3050-3097 arranged as four-car sets.
