Notice a little machine gun-toting, bomb-sniffing dog-leading company on your commute this morning?
Don't worry, it was just a drill.
Bomb squads and police in bulletproof vests were out in force at major transit hubs throughout the city, including Penn Station, Grand Central and Herald Square, as part of Operation RailSafe, a national anti-terror exercise designed to practice preparation and response in the event of a terrorist threat on the mass transit facilities.
While authorities said no specific threat incited today's surge, Commissioner Raymond Kelly pointed out, "40 percent of the attacks in the last 20 years have been against transit facilities."
Uniformed officers also rode the rails with bomb-sniffing dogs and held bag checkpoints at various locations as part of the drill. Police stepped up patrol along highly trafficked Amtrak routes and put more cops in the stations.
