• YONKERS, N.Y. (AP) -- The revelation that a New York City commuter train derailed while barreling into 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 authorities 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 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 senator said the wreck underscored the need for it.
• "This incident, if anything, heightens the importance of additional safety measures, like that one," said 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.
