The R211 is a new technology train (NTT) New York City Subway car being built by Kawasaki Railcar Manufacturing for the B Division and the Staten Island Railway (SIR). They will replace two aging subway car models: all R44 cars on the Staten Island Railway and all R46 subway cars. The order is split into three parts: R211A and R211T cars for the subway and R211S cars for the SIR. The R211Ts employ open gangways between cars, allowing passengers to see and walk through the entire length of the train – a feature not present on the subway's other rolling stock. The base order consists of 535 cars, with options for up to 1,077 additional cars.

Planning for the R211 order started in 2011. The design process started in 2012, at which time the order was supposed to consist of 75-foot-long (23 m) cars. The cars' lengths were changed to 60 feet (18 m) by 2015, and the first request for proposals was solicited in July 2016. After several changes to the proposal, the Metropolitan Transportation Authority (MTA) awarded a contract to Kawasaki in January 2018. Delivery of the pilot cars began at the end of June 2021. They contain new features such as wider doors, information displays, LED-lit doorways, open gangways, and LED interior lighting. The R211As entered service on March 10, 2023, beginning a 30-day acceptance test on the A. Following a successful second revenue service test with the pilot set, it officially entered service with the first production set on June 29, 2023. The R211Ts entered service on February 1, 2024, on the C.
