Amtrak train derails! Authorities cite excessive speed as the possible cause of Tuesday’s deadly Amtrak derailment in Philadelphia. But if the speed was an engineer’s mistake, that error could have been corrected by computer technology, reports CBS News’ David Begnaud.
In the Los Angeles area, where tens of thousands of people use commuter trains every day, Positive Train Control (PTC) is up and running and essentially lets a computer take over the controls of a train if it detects “engineer error” that could lead to potential danger.
“With a functioning positive train control system, as that train approached that curve, the technology would have actually slowed the train down or brought it to a stop in advance of it potentially speeding through the accident area,” former Federal Railroad Association administrator Joseph Szabo said.
