The Post reported last week:
Three of the biggest freight railroads operating in the U.S. have told the government they won’t meet a 2018 deadline to start using safety technology intended to prevent accidents like the deadly derailment of an Amtrak train in Philadelphia last May.
Several other railroads are reporting the same.
The technology at issue is "positive train control" or PTC. It "relies on GPS, wireless radio and computers to monitor train positions and automatically slow or stop trains that are in danger of colliding, derailing due to excessive speed or about to enter track where crews are working or that is otherwise off limits," the Post explains.
