Test Train.
R211A no. 4065 (Kawasaki, 2019-present) is the lead motor on a 5-car test train seen passing through 59th St station on the 4th Avenue Line. These cars, along with the other 5 that are currently on the property, are undergoing a slew of performance tests and evaluations prior to entering revenue service in the system. Upon successful completion of the tests, production will commence on the rest of the R211 order as well.
