A pair of survivors of the crash of a New York Metro-North commuter train are planning to sue the railway, according to a CNN report.
The passengers were among the approximately 150 who were on board a Metro-North train that derailed on its way to New York City from Poughkeepsie, N.Y. on Sunday morning.
Four passengers were killed in the accident, and about 70 others were injured.
"Bottom line is, the guy was going 82 mph in a 30 mph zone," Williams’ attorney Michael Lamonsoff told the network. "We have GPS on cars; they should have GPS on the trains.”
The National Transportation Safety Board (NTSB) is investigating the cause of the crash, which was the fourth accident on Metro-North in 2013.
The agency has focused on driver error, noting that the train was speeding in the moments before the crash.
The driver of the train has reportedly told investigators that he was “not 100 percent awake” before the train derailed.
