U.S. Transportation Secretary Ray LaHood has announced a $150 million grant to help Metro replace outdated rail cars.
The grant matches another $150million provided by Maryland, Virginia, and the District of Columbia.
Nearly $80 million of the money will allow Metro to purchase as many as 300 new 7000-series railcars.
The cars will replace Metro's current 1000-series cars -- cars that were cited by the National Transportation Safety Board as a contributing factor to the severity of passenger injuries and the number of fatalities in the Red Line crash in June of 2009.
The rest of the $300 million will go towards track rehabilitation and elevator and escalator improvements, and other station upgrades.
It includes $10 million specifically aimed at helping the transit agency address safety recommendations made by the NTSB.
