Yesterday morning, the FDNY, NYPD, Port Authority Police, Office of Emergency Management and additional agencies converged on the World Trade Center PATH station in lower Manhattan to participate in a full-scale exercise—Operation Safe PATH 2009— to test their response to an improvised explosive device detonation. While PATH service was suspended and the immediate area were closed off to vehicular and pedestrian traffic, over 800 emergency responders, plus 150 volunteers who portrayed victims, participated in the drill, which involved two (simulated) explosions that occurred on a NJ-bound PATH train about 1000-1200 feet into the tunnel. more ›

You're warned: This Sunday, the Office of Emergency Management is overseeing a drill that will, according to the AP, "simulate a response to an explosion at a PATH commuter rail train in the tunnel between the World Trade Center site and northern New Jersey. Officials say there will be no sound of an explosion, but emergency vehicles will respond with flashing lights and sirens." First responders from the NYPD, FDNY, and Port Authority will be on hand for the exercise; Vesey Street, on the north side of ground zero, will be closed to all but emergency vehicles and PATH rail service will be suspended from 6 a.m. to 11:30 a.m. more ›
