Metro said Tuesday that its outside lawyers were paid $7.5 million in fees for their work on lawsuits stemming from the 2009 Red Line crash.

The amount was revealed in response to a public records request by The Washington Post.

Metro said the $7.5 million was paid to the law firm of Wilson Elser. Metro redacted the hourly rate paid to the law firm, saying it was “proprietary and confidential information.”

Metro said that it paid $3.2 million of the bill and that its insurers — whom the agency did not name in the release of information — paid the balance of $4.3 million.

In response to another public records request, Metro disclosed in January a list of 84 payouts, totaling $1.6 million, that were paid to settle some of the claims connected to the crash, which killed nine and left dozens injured.

Those payouts did not include settlements from federal lawsuits filed in U.S. District Court.
