More than 800 first responders have staged a disaster drill at the World Trade Center PATH station.

The mock explosion happened Sunday morning on in the PATH tunnel linking lower Manhattan to New Jersey. Hundreds of firefighters, police officers and members of other New York City agencies took part in the drill.

They secured the scene and then brought the pretend victims up out of the tunnel.

There 150 volunteers playing victims wore makeup simulating blood and grime.

Officials bought TV ads and plastered train stations with posters to warn downtown residents of the drill. There haven’t been as many responders at ground zero since the Sept. 11 attacks.

“There will be street closures. We’ll put them out. They’ll be minimal and it’s also on a Sunday morning. It starts at 8 o’clock in the morning so there should be minimal disruption,” said NYPD Commissioner Ray Kelly before the training.

PATH rail service was suspended Sunday morning during the drill.

All streets south of Warren Street and north of Vesey, between Broadway and West Street were closed to vehicular and pedestrian traffic.
