“Out of an abundance of caution, the MTA has taken additional steps to enhance customary dynamic layers of security following recent international events. As the NYPD has indicated with regard to New York City, we are aware of no credible and specific threats to the transportation network at this time. The MTA routinely works closely with law enforcement partners at every level of government to ensure the safety of our customers and employees. We encourage all New Yorkers: if you see something that looks out of the ordinary, say something to MTA or law enforcement personnel.”
