The husband of the woman killed in the deadly Metro-North crash in Valhalla last year is using her memory to make sure the crossing doesn't claim any more lives.

On Feb. 3, 2015, a Metro-North Harlem line train packed with hundreds of evening commuters slammed into Ellen Brody's Mercedes SUV at the Commerce Street grade crossing. The Edgemont native and five passengers on the train died as a result of the crash.

Her husband, Alan Brody, says his wife's legacy will live on, but not in the way he hoped.

"I see this for what it is, a terrible breach of the public faith that I must go out and fix," he says.

The Brody family filed a lawsuit against Metro-North and others on the anniversary of the crash.

They say they are pushing for the changes that are necessary to ensure everyone's safety.

Metro-North declined to comment on the pending litigation.
