The collision between an SUV and a Metro-North train that left six people dead in Valhalla more than a year ago left many emotional scars, leading to calls for sweeping changes at railroad crossings. On Friday, local politicians teamed up with one man who lost his wife in the crash to ensure those changes happen.

Alan Brody's wife, Ellen, was the driver of the SUV that wound up on the tracks in Valhalla when the warning gates came down on the vehicle. She was among the six killed.

Brody, state Sen. David Carlucci and Assemblyman Tom Abinanti were back at the scene Friday, pushing for a statewide study of all rail grade crossings.

There are more than 5,000 railway crossings throughout New York state. Lawmakers say that most of them are unsafe because their warning mechanisms are simply outdated.

Alan Brody filed a lawsuit in February accusing Metro-North and Mount Pleasant officials of wrongful death and negligence.
