Rail Freight Positive Train Control
Description
Positive train control (PTC) is advanced technology specifically designed to automatically stop or slow a train before certain accidents occur. In particular, PTC is designed to prevent train–to–train collisions, derailments caused by excessive speed, unauthorized incursions by trains onto sections of track where repairs are being made and movement of a train through a track switch left in the wrong position.
