Amtrak derailment focuses attention on railroad safety technologies

Positive train control, or PTC, seeks to create a complex infrastructure network for railroad lines which enable the real-time sharing of information between trains, rail wayside devices and software programs referred to as “back office” applications. The communication system tracks a train’s position and movement and determines any speed restrictions as well as the state of signal and switch devices along a railway. If a railway vehicle is speeding or a risk of a collision develops, the PTC system takes control of the train away from a human operator to reduce the speed or take other actions to prevent a collision.
