WASHINGTON, D.C. — Many investigators say Positive Train Control (PTC), an automated safety system, could have prevented last month’s Amtrak train derailment. Amtrak officials have said they will have PTC installed throughout the northeast corridor by the end of this year, which is the deadline mandated by Congress, according to NPR.
But the vast majority of other commuter railroad systems, which provided nearly 500 million rides in 2014, won’t be able to fully implement positive train control for several more years, the report said.
