Metro is expected to get $150 million in federal funding — the fifth installment of dedicated monies for the transit agency to help it improve its safety.

The Senate Appropriations Committee approved the funding as part of the fiscal  2014 Transportation, Housing and Urban Development and Related Agencies (THUD) Appropriations bill.

The money for Metro is the fifth installment the transit agency has received from the federal level, following the deadly Red Line crash in 2009 that killed nine people and injured dozens.

“Following the tragic Red Line crash, there was an outcry for safety,” said U.S. Sen. Barbara Mikulski (D-Md.) in a news  release. “I demanded new leadership and a new culture of safety at Metro. Today we’ve got new leadership, the first-ever federal safety standards for [Metro] systems and a dedicated stream of federal funding.”

The federal money is part of a $1.5 billion package over 10 years to fix Metro’s aging infrastructure and to help upgrade its older rail cars and improve its signal system.

The House version of a similar funding bill for Metro gives the agency $125 million.
