Imagine a Metro train disaster deep in a tunnel. It could take 45 minutes for first-responders loaded with gear to walk to the scene.
But that's about to change.
Metro's emergency response exercise on Feb. 13 at the Rosslyn Metro station will debut new technology -- a MERV cart.
Officials said the Mobile Emergency Response Vehicle turns that 45-minute walk into a four-minute ride.
The U.S. Department of Homeland Security provided money for 26 of the carts.
Metro is the first transit system in the country to get one. The carts were used successfully during a terror attack in the London transit system. They are made of aluminum and can be carried by responders.
The Feb. 13 Metro exercise is one of three where the system and its regional partners will be practicing emergency response.
No service will be disrupted because they'll be conducted during off hours and on closed tracks, Metro said.
