YONKERS, N.Y. (AP) — The revelation that a New York City commuter train derailed while barreling around a sharp curve at nearly three times the speed limit is fueling questions about whether automated crash-avoidance technology could have prevented the carnage.
Safety officials have championed what's known as positive train control technology for decades, but the railroad industry has sought to postpone having to install it because of the high cost and technological issues.
Investigators haven't yet determined whether the weekend wreck, which killed four people and injured more than 60 others, was the result of human error or mechanical trouble. But some safety experts said the tragedy might not have happened if Metro-North Railroad had the technology, and a lawmaker said the derailment underscored the need for it.
"This incident, if anything, heightens the importance of additional safety measures, like that one," said U.S. Sen. Richard Blumenthal, a Democrat from Connecticut, which also is served by Metro-North. "I'd be very loath to be more flexible or grant more time."
The train was going 82 mph as it entered a 30 mph turn Sunday morning and ran off the track, National Transportation Safety Board member Earl Weener said Monday. He cited information extracted from the train's two data recorders; investigators also began interviewing the train's crew.
The speed stunned officials — "I gulped," said U.S. Sen. Charles Schumer, D-N.Y. Gov. Andrew Cuomo said the NTSB findings make it clear "extreme speed was a central cause" of the derailment and vowed to "make sure any responsible parties are held accountable" after investigators determine why the train was going so fast.
"At this point in time, we can't tell" whether the answer is faulty brakes or a human mistake, Weener said.
Investigators began talking to the train's engineer Monday but postponed completing the interview, likely until Wednesday, National Transportation Safety Board spokesman Keith Holloway said Tuesday. Holloway wouldn't say why; union leader Anthony Bottalico said it was because William Rockefeller hadn't slept in almost 24 hours and was "very distraught."
