NEW YORK (AP) -- A week after four people died in a New York commuter train derailment, two federal lawmakers proposed Sunday that trains nationwide be outfitted with cameras pointed at engineers and at the tracks.
"I know you're going to hear from Metro-North that there are costs, but the costs of these audio and visual recorders is minuscule, in fact negligible, compared to the hundreds of millions of dollars that this tragic incident will cost Metro-North in the end," said Sen. Richard Blumenthal of Connecticut who joined New York Sen. Charles Schumer for a news conference at Manhattan's Grand Central Terminal.
Last Sunday, a Metro-North Railroad train approached a curve on the tracks just north of Manhattan going at 82 mph instead of the speed limit of 30 mph. Rail cars careened off the tracks, with the front car ending up inches from the water where the Hudson River meets the Harlem River.
A lawyer and union leader for the derailed train's engineer, William Rockefeller, have said the train's hypnotic motion may have caused him to experience a "nod" or a "daze" at the controls.
The Democratic lawmakers are urging the Federal Railroad Administration to demand the implementation of a measure they say might prevent the kind of deadly Metro-North derailment that also left dozens of people injured.
The National Transportation Safety Board first recommended installation of the audio and video recording cameras in locomotives and operating railway cabs five years ago.
The railroad administration issued a statement saying that safety was its "highest priority" and 2012 was the safest year in railroading history.
"We support the use of cameras in cabs to further improve safety," the agency said, adding that it continues to work with the NTSB on the investigation into the New York accident.
The NTSB did not immediately respond to a call for comment on Sunday, nor did the Metropolitan Transportation Authority that runs Metro-North.
Schumer said fatigue was suspected in two collisions - one in Iowa, in 2011 and another in Newton, Mass., in 2008 - and might have been proven if cameras were present. He said such images might have caught behavior patterns that could have been prevented in the future.
"Get on board and implement these recommendations now," Schumer said, directing his comments to the Federal Railroad Administration, which has the power to demand the changes. The railroad administration has yet to take any regulatory action putting these recommendations in place.
"Shame on Metro-North for failing to adopt this system," Blumenthal said. "Shame on the operators of this railroad for failing to move forward with a recommendation that is so cost effective. Keep people alive."
The NTSB's recommendation for the monitoring program followed a train collision in California that killed 25 people, including the engineer, and injured more than 130. The NTSB said the engineer's texting was the primary cause of the accident.
In a letter this week to the NTSB, the two senators noted that "in the wake of a 2008 railway collision in California, the NTSB recommended inward facing cameras, which would monitor train crew performance, as well as outward facing cameras, which would be used to monitor crossing accidents and to recognize any deficiencies on the tracks."
Schumer and Blumenthal said they believe such recording devices "may be used as a deterrent for dangerous behavior, like falling asleep or texting, and may also be used after a rail crash to determine the cause of the crash."
Amtrak locomotives and California's Metrolink commuter rail have outward facing cameras that record signals and gate crossings.
