“Early today, just after 1 a.m. a northbound A train became separated between the sixth and seventh cars of the ten-car train as it entered Chambers Street Station. Ten passengers were safely evacuated with no reported injuries to customers or employees.

“At this time, we believe this to be an isolated incident, however, I am launching a full investigation, and out of an abundance of caution, the entire R179 fleet is being pulled from service until further notice. We have redeployed additional spare cars and minimal impacts to service are anticipated.

“This marks the latest unacceptable issue with one of Bombardier’s R179 cars. Customer and employee safety is New York City Transit’s North Star. We will not compromise one inch on safety. We will not return the fleet to service without certainty and validation that all cars are fit for passenger service – period.”
